By ensuring a rigid, low-deflection interface between the machine casing and the transducer, the housing eliminates signal noise caused by mechanical resonance. This assembly is engineered to maintain the probe's calibrated position, ensuring the transducer maintains the specified gap voltage (typically centered at -10 VDC) required for linear shaft displacement monitoring.
