product description 

The Bentley 3500/42 Displacement/Velocity acceleration Monitor is a device that receives 

input from a Bently Nevada displacement sensor, processes the signal to generate various 

vibration and displacement measurements, and compares the processed signal to a 

user-programmable alarm setting point.

The 3500/42 displacement/Velocity acceleration monitor has the following features:

Flexibility: It can accept signals from one to four proximity, acceleration or speed sensors, 

enabling it to respond to many different monitoring needs.

Visualization: Each channel has its own coaxial connector on the front of the display for direct 

viewing and connection by the user.

Safety: Each connector has built-in short-circuit protection to prevent possible circuit problems 

from causing damage to the device.

High resolution: With high resolution, it can provide accurate monitoring results.

The operating principle is as follows:

Sensor signal reception: First, the 3500/42 receives the signal from the displacement sensor. 

These sensors can be proximity, acceleration or speed sensors to monitor vibration and 

displacement of machines or structures.

Signal processing: The received signal is processed by the circuits inside the 3500/42. The 

processing involves amplifying, filtering and adjusting the signal to extract useful information 

and eliminate noise interference.

Measurement generation: The processed signals are used to generate a variety of vibration 

and displacement measurements. These measurements can be radial vibration, thrust position, 

differential expansion, eccentricity, etc., depending on the user's requirements and configuration.

Alarm comparison: The generated measurements are compared to user-programmable alarm 

setting points. If the alarm value set by the user exceeds the measured amount, 3500/42 triggers 

an alarm.

Output indication: OK LED light will light up when 3500/42 is working properly. In addition, there 

are other LED indicators to show different operating status and alarm conditions, such as the 

TX/RX LED indicates the connection status with other modules in the 3500 rack, and the bypass 

LED indicates whether the seismic monitor is in bypass mode.
