All-Inclusive Hardware Solution

The OleumTech® OTC Wireless Vibration Transmitter provides the ability to remotely monitor the run/stop status (on/off) of a critical process equipment using low frequency vibration detection.  The Vibration Transmitter is a fully integrated solution that provides an accelerometer and a replaceable battery pack.  The hassle of wiring and running conduit for the sensor is completely eliminated with the provided weatherproof 20 ft cable and M12 keyed connection.  The sensor can be configured for X, Y, or Z-axis orientation to perfectly suit your application.  The accelerometer can be calibrated for automatically setting the operating threshold.  You can also control the signal gain of up to 5X using the Waveform Gain parameter.

Safe, Scalable, and Easy to Use

No third-party mounting hardware is required since the provided accelerometer is equipped with magnetic direct mounting hardware that makes installation extremely quick and easy.  The wireless accelerometer provides up to a 10-year life before needing a battery replacement. It communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network creating a highly scalable network, accommodating virtually any I/O requirement.  The OleumTech Wireless Transmitter is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is intrinsically safe, designed not to cause a spark and can be serviced without being removed from a process
