Product Description
The 18745-04 is a high-precision Proximitor Sensor from the legacy Bently Nevada 7200 Series. It converts the high-frequency eddy current signal from a 5mm probe into a linear voltage output proportional to the gap between the probe tip and the rotating shaft. This allows measurement of both static position and dynamic vibration.
The sensor features a rugged aluminum housing and is calibrated for a 9.0-meter total system length, ensuring accurate operation in legacy vibration monitoring systems.

Application
The 18745-04 is used in legacy condition monitoring systems for rotating machinery in power plants and older industrial facilities. It monitors centrifugal pumps, motors, and fans, providing early warning for shaft misalignment, bearing wear, or excessive vibration that could lead to catastrophic failure.
Technical FAQ
Can this be used with a 3300 XL probe?
No. The 18745-04 is calibrated specifically for 7200 Series 5mm probes. Mixing series will cause calibration errors and inaccurate vibration readings.
Why is the 9-meter length critical?
Proximitor sensors are tuned to a specific total electrical length (probe + extension cable). Using a shorter cable will result in incorrect output voltage, leading to false alarms or missed vibration events.
