Michigan Scientific’s AMP-SG-MH-BC Strain Gage Amplifiers are ideal for applications where signal conditioning is needed and space is limited. They are designed to provide signal amplification prior to passing the signal through a slip ring. Superior data accuracy is achieved by locating the signal amplifier on the rotating side of the slip ring. This configuration greatly improves signal quality because the amplifier is located closer to the sensor, which reduces errors due to long lead wires, connector resistance variations, and electromagnetic interference.

A full strain gauge bridge is needed to allow the AMP-SG-MH-BC to regulate the bridge excitation. The AMP-SG-MH-BC has completion resistors built-in for either quarter or half bridge measurements. Without a quarter or half bridge connected properly, measurement of the excitation is not meaningful.

These strain gage amplifiers incorporate a precision low drift bridge excitation supply, a stable differential amplifier, and a remotely activated shunt calibration resistor for system span verification. Each amplifier provides strain gauge bridge excitation and amplification for one channel. Multiple channel configurations are available.

External mounting brackets for mounting the amplifier to flat surfaces and shafts one inch in diameter or larger are available. 


Specially designed mounting brackets compatible with both the AMP-SG-MH and AMP-SG-MH-BC are available. These mounting brackets are ideal for mounting the amplifier to flat surfaces and shafts one inch in diameter or larger. They can be easily and securely mounted with bolts or screws, hose clamps, or wide cable ties for a clean and quick mounting solution. Using the mounting bracket eliminates the need for messy adhesives and it traps the amplifier in all six directions.
