Michigan Scientific’s end of shaft slip ring assemblies are used to make electrical connections to thermocouples and strain gages and mount directly on the end of a shaft. They have two components; a rotor, which rotates with the shaft, and a stator, which is stationary and passes the signal to the DAQ. The signals originate at a sensor, strain gage, or thermocouple, that are lead to the rotor so that the signal passed through the stator to the DAQ. Commonly, the sensors are used to measure torque, stress, temperature, vibration, and acceleration on devices for wheel testing, halfshaft measurement, gear box measurements, powertrain testing, and many other applications.
10, 20 or 36 circuits
2” and 2.5” diameter rotor flanges
Rotation sensor, options:
(E) optical encoder, quadrature outputs (50, 100, 256, 360 or 512 ppr) & index pulse. Encoder pulse location accuracy 0.25°.
(R) resolver, which is an absolute analog position sensor.
(T) tachometer, optical encoder explained in (E) and instantaneous analog velocity and angular position outputs, which are easy to record.
The PS-DC controls the amplifiers, and the excitation to strain gage bridges, and commands spinning strain gage amplifiers to apply their internal shunt calibration resistor to the appropriate arm of the strain gage bridge.
