The 3500/64M 140734-05 Dynamic Pressure Monitoring Module is a 4-channel industrial grade dynamic pressure monitoring module launched by Bently Nevada, and is a core component of the 3500 series mechanical protection system.
1、 Core product parameters
Basic specifications: Belonging to the BENTLY Bentley 3500 series, it is a single slot, four channel dynamic pressure monitoring module that supports the connection of 1-4 pressure sensor signals.
Electrical characteristics: The input impedance of the 3-wire sensor is 10 k Ω, the 2-wire sensor has a typical value of 1.5 M Ω~3.5 M Ω, and the dynamic pressure sensitivity is 100 mV/psi (1.45 mV/mBar). It is equipped with OK, TX/RX, and Bypass status indicator lights, supports high/low filtering modes, and can customize alarm delay.
Configuration capability: Through the 3500 rack configuration software, bandpass corner frequency and additional notch filters can be set, supporting cascade mode. A single sensor input can be allocated to all 4 channels, adapting to different filtering and range requirements.

2、 Application scenarios
This module is mainly used for status monitoring of rotating industrial equipment, which can accurately collect dynamic pressure data of liquids and gases inside the equipment, achieve real-time operation status tracking, timely identify abnormal pressure exceeding conditions, predict potential equipment failures in advance, and synchronously upload data to the central control system for remote analysis. It is widely used in safety protection scenarios of key power equipment such as steam turbines, compressors, and fans.

The related supporting models belonging to the Bentley 3500 monitoring series include:
3500/61 Temperature Monitoring Module
3500/62 Universal Monitor Module
3500/63 gas detection module
3500/42M displacement monitoring module
4、 Common problem solving
Channel without signal input: First check if the sensor wiring is loose, if the input impedance matches the module specifications, and then confirm that the channel has not been disabled through the 3500 configuration software.
Alarm false triggering: Check whether the bandpass filtering parameters and alarm delay settings are suitable for the on-site working conditions, and investigate whether there are signal jumps caused by electromagnetic interference.
Data communication interruption: Check if the backplane connection between the module and the rack is reliable, and confirm that the communication configuration of the upper monitoring system matches the module address.
