Ensure your monitor channel cards (such as the Bently Nevada 3500\/42M) are explicitly configured to accept moving-coil (seismic) sensors. Attempting to run this on a standard accelerometer or IEPE channel configuration will produce signal clipping or no-reading errors.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eNever exceed the maximum structural temperature of 204 degC. Even though the body is designed for high temperatures, the interconnecting cabling must be insulated with FEP or glass braid. Avoid routing signal cabling along steam piping or unprotected thermal bridges without proper standoff brackets. Because this is a moving-coil sensor, physical drop damage can misalign the internal suspension springs, causing permanent sensitivity loss or signal distortion.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eAlways verify that the mounting surface is machined flat to at least 0.02 mm (0.001 inches) and free of rust or slag. Tighten the sensor to the specified torque. Avoid over-torqueing, which can warp the base and degrade the transducer frequency response.
