The Bently Nevada 128229-01 is a Prox/Seismic I/O Module with built-in terminations. It is made for the 3500/42M Proximitor Seismic Monitor system. It lets you monitor four channels of proximity and seismic transducers to protect machinery in industrial situations like oil and gas or maritime engineering. This module prepares signals to measure vibration, location, and other related factors while comparing them to alarms that can be programmed.
Important Features:
-> Channels can be paired for measurements such as radial vibration, acceleration (RMS or peak), velocity, thrust position, REBAM, differential expansion, shaft absolute, eccentricity, or circular acceptance zone.
-> It mostly works with Seismoprobe transducers, although it can also work with Prox/Accel and Velomitor (not advised).
-> The front panel has LEDs for OK, TX/RX, and Bypass, as well as buffered transducer outputs and recorder outputs that range from +4 to +20 mA.
