Model: 3500/42-01-00 176449-02 | 128229-01 |138708-01
Features:
(4) Channel Monitor
Accepts Input from Proximity and Seismic Transducers
Machinery Protection
Provides Essential Machine Information
The Bently Nevada 3500/42M 138708-01 Series Proximitor / Seismic Monitors are four-channel monitors that accept input from proximity and seismic transducers, condition the signal to provide various vibrations and position measurements, and compares the conditioned signals with user-programmable alarms.

You can program each channel using the 3500 Rack Configuration Software to perform the following functions: Radial vibration, Thrust position, Differential expansion, Eccentricity, REBAM, Acceleration, Velocity, Shaft absolute, and Circular acceptance region.

The primary purpose of the 3500/42M 138708-01 Proximitor / Seismic Monitor is to provide machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms. The modules also provide essential machine information for both operations and maintenance personnel.
Feature
Input function: 138708-01 can receive various types of signals, such as switching signals (on-off signals), analog signals (continuously changing voltage or current signals), etc., to input the status or data of external devices into the control system.
Output function: According to the instructions of the control system, the signal is output to the external device to control the operating state of the device, such as controlling the opening and closing of the relay, driving indicator light on and off, adjusting the analog output to control the action of the actuator, etc.
Application scenario
Industrial automation control: 138708-01 In the industrial production process, used to connect various sensors (such as temperature sensors, pressure sensors, etc.) and actuators (such as motors, valves, etc.), to achieve the monitoring and control of the production process.
Intelligent building system: such as lighting control, air conditioning system control, security system, etc., to achieve centralized management and automatic control of various equipment in the building.
Power system: 138708-01 In the power monitoring system, various parameters in the power system (such as voltage, current, power, etc.) can be collected, and the control signal is output to the switchgear, protection device, etc., to ensure the safe and stable operation of the power system.
