140734-01 | Bently Nevada 3500/40M Proximitor Monitor

The following is the relevant information of Bently Nevada 3500/40M Proximitor Monitor (Component number 140734-01) :

Overview

The 3500/40M is a four-channel monitor, mainly used to receive input signals from Bently Nevada proximity sensors, conditioning the signals to provide various vibration and position measurement values, and comparing the conditioned signals with user-programmable alarm values.

Function

Measurement functions: Each channel can be programmed through the 3500 rack configuration software to achieve multiple functions, including radial vibration measurement, eccentricity measurement, rotor axial position and velocity measurement (REBAM), thrust position measurement, and differential expansion measurement, etc.

Signal processing: After the input signal is conditioned, various parameters known as static values will be generated. For each active static value, alarm set points can be configured, including warning set points and danger set points, to precisely monitor key parameters.

Alarm logic: Equipped with complex alarm logic, it can be programmed using 3500 rack configuration software. It can define complex alarm conditions through "and" OR "logic as well as alarm inputs from any monitoring channel (alert and dangerous states)," non-OK "states, or individual PPLs (process alarm states).

Technical parameters

Input signal: Accept signals from 1 to 4 proximity sensors.

Power consumption: The typical value is 7 watts.

Input impedance: 15kΩ.

Output impedance: 550Ω.

Sensor power supply: -24V DC.

Operating temperature: -30 °C to + 65°C (-22°F to + 150°F) when used with internal/external terminal I/O modules; When used in conjunction with the internal barrier I/O module (internal terminal), it operates at 0°C to + 65°C (32°F to + 150°F).

Measurement accuracy: The measurement accuracy of direct measurement/gap measurement / 1x frequency / 2x frequency is ±0.33% of full scale. The measurement accuracy of Smax is ±5% of the maximum value.

Application

It is mainly applied to the monitoring of key rotating machinery, providing important machine information for operators and maintenance personnel to optimize equipment performance and prevent faults. It is widely used in manufacturing, chemical, power generation and other industries.
