Ted NachazelOctober 1, 2024BlogMichigan Scientific Corporation (MSC) Wheel Pulse Transducers are distance measuring instruments (DMI) that provide accurate reliable distance measurements for georeferencing and mobile mapping systems.
Compatible with vehicle-based mobile mapping systems (MMS), the Wheel Pulse Transducer mounts directly to the vehicle wheel and integrates with position and orientation (POS) and imaging modules to provide crucial distance data to supplement GPS/GNSS signals. A recent case study illustrates how high-resolution Wheel Pulse Transducer data not only helps to compensate for breaks in GPS signal but can outperform GPS sensor performance/distance tracking accuracy.
Michigan Scientific Wheel Pulse Transducers have proven to be a durable alternative to OEM DMIs for acquiring mobile mapping data in rugged environments. Building on MSCs decades of experience with on-vehicle slip ring technology, the weatherproof Wheel Pulse Transducer is ideal for testing in rainy, snowy, or dirty environments.
How do DMIs Work?
Distance measuring instruments or indicators include wheel sensors or odometers that calculate distance traveled based on the number of the vehicle’s wheel rotations. The encoder inside the DMI uses optical technology to generate pulses or output signals representing partial revolutions of the vehicle wheel to determine the precise linear distance traveled.
The DMI is connected to the vehicle’s wheel and the vehicle-mounted mobile mapping system.
MSC Wheel Pulse Transducers provide reliable measurements to aid in mapping innovation. End users can use multi-sensor fusion SLAM (simultaneous localization and mapping) algorithms to pair the DMI with LiDAR sensor technology, high-resolution cameras, and GPS technology. This allows users to collect precise geospatial data for incredibly detailed mapping and indoor/outdoor 3D modeling. DMI technology simplifies data collection in even the most challenging environments in urban planning, infrastructure development, and environmental monitoring applications.

Ted NachazelMay 21, 2024BlogUnderstanding the dynamic forces acting on tracked vehicles (continuous tread/caterpillar track) offers the insight necessary to create more capable machines. Tracked vehicles achieving higher speeds, heavier loads, and increased durability will require extensive testing. Advancements in FEA/FEM have enabled simulations to include complete tracked running systems. The mapping of movements and interactions of individual components of the system allows for the evaluation of complex loads in a variety of scenarios. These simulations provide insight into expected forces experienced by various components within the system, a crucial step in design and prototyping. Real-world testing is used in various stages of the design and prototyping to validate the results of FEA. To create useful FEA, the forces experienced by the individual components as well as the full system must be validated with physical tests.
Vehicle Dynamic Testing on Tracked Vehicles:
Ground to Hull Forces: Key force inputs are transmitted from the ground to the vehicle’s hull. An important issue related to the use of tracked vehicles is the phenomenon of vibration. Understanding track vibration is essential to evaluating the durability of track components and the vibration energy transmitted to the vehicle. This can heavily impact wear to individual components as well as personnel within the vehicle. Dynamic testing helps engineers optimize the vehicle’s suspension, steering, and overall handling characteristics to ensure peak performance in the intended environment.
Weight Reduction: Weight reduction of tracked vehicles can play an important role in fuel consumption as well as the transportation of vehicles via ground or air. Heavier vehicles also increase the wear of driveline and running gear components. In combat vehicles such as unmanned ground vehicles, Armored Personnel Carriers (APC), or tanks, it can be crucial to reduce weight to transport armored vehicles by air to regions of conflict. Military vehicles with continuous tracks have an increasing need for armor while maintaining existing dimensions and mobility characteristics.
Durability Testing: Tracked vehicles undergo intense wear and tear, especially during military operations or heavy-duty agricultural tasks. Dynamic testing allows engineers to evaluate the durability of key components, identifying weaknesses and areas for improvement to enhance the vehicle’s overall lifespan. Tracked vehicles are designed for specific tasks, and their performance is heavily reliant on their ability to navigate different terrains efficiently.
Precision in Design: Engineers strive to create vehicles that are not only powerful but also precise in their movements. Dynamic testing provides valuable data on a vehicle’s responsiveness to steering inputs, acceleration, and braking, aiding in the refinement of design elements for improved control and maneuverability.
Michigan Scientific Corporation Wheel Force Transducers:
Accurate Measurement of Forces and Moments: Michigan Scientific Wheel Force Transducers (WFTs) are sensors that accurately measure the forces and moments applied to each wheel. This data includes vertical, longitudinal, and lateral forces, as well as pitch, roll, and yaw moments. This allows engineers to obtain detailed insights into how the vehicle interacts with the terrain and responds to various inputs. This data is essential for understanding how continuous track vehicles respond to varying terrains, loads, and operational conditions. Wheel Force Transducers can be installed on both road wheels and the idler.
Real-time Data Acquisition: These transducers enable real-time data when used with commercially available data acquisition systems. This allows engineers to monitor and analyze a wide range of parameters, including tire forces, wheel speeds, and suspension dynamics. This information is invaluable for making informed decisions about design modifications and improvements.
Versatility: Michigan Scientific WFTs are designed to be versatile and can be easily adapted to different vehicle configurations. Whether testing a military tank, an agricultural crawler, or a construction vehicle, these transducers offer a flexible solution for diverse applications.
Robust Design for Harsh Environments: Tracked vehicles often operate in harsh and unpredictable environments. MSC WFTs are engineered to withstand these conditions, providing accurate measurements even in extreme temperatures, vibrations, and rugged terrains. This durability ensures that the transducers perform reliably in the field. Tracked vehicles often operate with varying loads, such as equipment or cargo. WFTs provide real-time information on load distribution across the wheels, allowing engineers to ensure structural integrity and stability.
Custom Adapters: Michigan Scientific will design and manufacture adapters for each tracked vehicle. MSC can also advise on and review the adapters designed by customers.
Instrumentation in the Track Mechanism and Suspension System
Michigan Scientific is also capable of instrumenting other critical components within the track mechanism and suspension system. Insight into track tension and the forces exerted on the idler wheel can be achieved using custom force transducers, based on our Wheel Force Transducers. Instrumenting the drive sprocket for torque measurements is also well within Michigan Scientific’s capabilities.
Drive Sprocket and Idler Wheel: Insight into track tension and the forces exerted on the idler wheel can be achieved using Wheel Force Transducers. Michigan Scientific can also adapt our wheel force technology to meet the size and strength required to get accurate measurements from the drive sprocket.
Torsion Bar: Torsion bars are a key component of a tracked vehicle’s suspension system. The characteristics of a tracked vehicle suspension system impact the speed, handling, reliability, and durability. Michigan Scientific can help achieve accurate measurements of the stress experienced by torsion bars using expert knowledge and years of gauging experience.
Drive Sprocket teeth: Michigan Scientific has experience gauging gear teeth. Contact forces between the sprocket teeth and each link of the track can be a valuable source of information on torque transmission.
The performance of tracked vehicles in both the military and work sectors is difficult to predict. They are designed to overcome the most difficult terrain and conditions while being reliable and durable enough to stay operating in the field. Rigorous testing is necessary to develop vehicles that are capable of handling such environments. Michigan Scientific Corporation offers the instrumentation capable of measuring those forces in the field.

Ted NachazelApril 11, 2022Custom Strain Gauge Transducers
Michigan Scientific specializes in designing and creating custom strain gauge transducers. Our engineers have expertise in gauging a wide variety of stock components. We develop and fabricate vehicle component strain gauge transducers that measure vehicle suspension forces, powertrain torques, steering component forces, engine and motor loads, and braking torques on vehicles in the field. Michigan Scientific is able to help customers obtain accurate data on the forces experienced by a part, while maintaining its strength and other characteristics as much as possible. Michigan Scientific engineers and technicians have completed applications across several industries. We specialize in custom applications.
Shaft Torque Transducer
When applying strain gauges to a shaft, the goal is to obtain accurate data on the forces experienced by the shaft, while changing its strength and other characteristics as little as possible. The shaft then acts as a transducer itself. The strain gauged shaft, now a transducer, can be used in the same way as a standard shaft to measure the forces that occur in normal usage.
Half Shaft Strain Gauging
We strain gauge OEM half shafts to measure torque. The signals are amplified using our wheel instrumentation package (WIP) before they are transmitted by our ERT slip ring assembly. The ERT can provide speed and angular measurement signals too. The model PS-DC Remote Amplifier Control Unit controls the WIP and supplies power to the ERT.
Driveshaft Strain Gauging
Driveshafts can be gauged for torque and thrust. Michigan Scientific has developed a compensation bridge to reduce cross-talk from torque into the thrust bridge. After the shaft has been gauged, the data can be transferred from the shaft via telemetry or slip ring.
Crankshaft Transducer
One of the more complex examples of a custom strain gauge transducer is creating a crankshaft transducer. Strain gauges are applied on a standard crankshaft in order to measure engine torque. The wires are routed through the crankshaft to connect to spinning amplifiers and a slip ring or telemetry system mounted on the pulley at the front of the engine. In these applications, multiple channels of strain measurements are collected for analysis.
Axial Force Gauging
Our custom tie rod end transducers can measure the axial forces acting on the tie rod during steering. Tie rod end transducers can replace the inner or outer tie rod end, based on customer needs. The custom tie rod transducer does not take up any additional space underneath the vehicle and no modification to the vehicle is required. Almost all tie rods can be made into custom tie rod transducers.
Shear Pin Transducer
Each application is custom designed to fit your application. The transducers are all machined from transducer-grade stainless steel and have a weatherproof coating. Our shear pin transducer is suitable for in-field data collection in addition to laboratory test setups. The shear pin transducer is easily adaptable to a wide variety of applications, is designed to not change the position of other vehicle components, and requires minimal modification to other parts.
Check out our Common Custom Transducers blog for more information on how we instrument parts to be used as transducers.
On-Site Strain Gauging
Michigan Scientific is capable of installing strain gauges on-site, at customer locations. Both component and structural applications can be instrumented for measurement and analysis. The customer’s components can be instrumented and data recorded to support a wide range of test and development activities. Components can be recorded during the manufacturing processes or in-service use. Michigan Scientific also has experience instrumenting structural beams for deflection and stress testing.
Instrumentation applications range from circuit board instrumentation for monitoring stress, thermal chamber door panel monitored for deformation during manufacturing, and fully instrumented industrial sized drive shafts. In the large drive shaft application, torque, acceleration, and rotational velocity were measured on a 16 inch diameter drive shaft of a large cement plant ball mill. Michigan Scientific also collected and analyzed the data from this project.
Michigan Scientific also uses decades of experience to install strain gauges in holes up to six inches deep and with a minimum diameter of 0.5 inches.
Data Acquisition and Reporting
Michigan Scientific provides on-site and remote data acquisition services for recording instrumented components under test. Additional data processing, analysis, and reporting services are also offered. [...]
