Bently Nevada’s 3500/40M 125680-01 is a four-channel displacement monitor module designed specifically for industrial applications, with high-precision measurement and programmable alarm functions. It is used in a wide range of industrial applications to provide reliable assurance for mechanical vibration and displacement monitoring.
​As part of the 3500 series, the 3500/40M 125680-01 module receives inputs from Bently Nevada proximity sensors and processes these signals to generate a variety of vibration and displacement measurements. It occupies a full-height front panel slot that monitors the vibration and displacement of the equipment in real time, and ensures the stable operation of the equipment through high precision measurement and data analysis, preventing failures caused by excessive vibration or abnormal displacement.
​The module has a variety of features, including:
​Radial vibration monitoring
Eccentric monitoring
REBAM (Rotating Equipment Balance Analysis)
Thrust position monitoring
Differential expansion monitoring

The design of the 3500/40M 125680-01 module allows the user to program each channel through the 3500 rack configuration software to perform the above functions. Depending on the configuration, each channel can generate a different static value, and the user can configure an alert set point for each activity’s static value and a danger set point for any two activities’ static values.
​In addition, the 3500/40M 125680-01 module has the following technical specifications:
​Signal input: Receive 1 to 4 proximity sensor signals
Power consumption: Typical value is 7.7 watts
Input impedance: The standard I/O is 10kΩ, and the effective impedance of the three parallel channels of TMR I/O is 50kΩ
Various static values are output, including radial vibration, thrust position, differential expansion, eccentricity, and REBAM related parameters
The 3500/40M 125680-01 module is suitable for a variety of industrial environments, including power, petrochemical, iron and steel metallurgy, providing monitoring and protection solutions for critical equipment to ensure stable operation and production safety
