Features:

  • Interface Between Proximity/Seismic Transducers and 3500 Rack Monitoring System
  • Combines Capability of Signal Conditioning with Multi-Function Monitoring Support
  • Operates in Conjunction with the M Series and Standard 3500 Monitors
The 3500/42M 176449-02 operates as the Proximitor Seismic Monitor in a 3500 rack, providing continuous machinery protection by comparing monitored parameters against configured alarm setpoints. It continuously accepts input from proximity and seismic transducers, conditions the signals to provide vibration and position measurements, and distributes these conditioned signals through the rack backplane to support steady state operation of all monitoring functions. Seamless channel programming is standard with the 3500/42M 176449-02, however using flexible configuration options will allow simultaneous execution of multiple monitoring functions across its four channels. The 3500/42M 176449-02 has made improvements in several areas over previous monitor designs in addition to incorporating universal transducer input capability within the 3500 rack.

The 3500/42M 176449-02 provides essential monitoring functions common to the entire rack, and is a critical component of the protection path, directly affecting the proper, normal operation of the overall monitor system. One 3500/42M 176449-02 monitor module is required per monitoring application depending on the desired channel configuration. The 3500/42M 176449-02 occupies only a single full-height slot in the rack and can be located in any available monitor slot position.

For Multi-Function Monitoring applications, the 3500/42M 176449-02 supports paired channel programming installed within the module. In addition to standard single function operation, the paired configuration also performs automatic signal processing. The 3500/42M 176449-02 dual channel pairing executes monitoring using the internal circuitry specified in the configuration options. Using this method, the monitoring system continually processes the health of all inputs. If the system detects that any monitored parameter exceeds configured alert or danger setpoints, it will automatically drive alarms and place an event in the System Event List.

The 3500/42M 176449-02 Bently Nevada Proximitor Seismic Monitor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The 3500/42M 176449-02 Proximitor Seismic Monitor is a four-channel monitoring module designed to accept inputs from both proximity and seismic transducers. It conditions these incoming signals to deliver precise vibration and position measurements, while also comparing the conditioned outputs to user-programmable alarm thresholds for reliable machine protection.

Using the 3500 Rack Configuration Software, each channel of the 3500/42M 176449-02 can be configured to monitor and report a variety of parameters. These include radial vibration, acceleration, eccentricity, REBAM, differential expansion, circular acceptance region, thrust position, shaft absolute, and velocity. The flexibility of these options allows users to tailor the monitor’s functionality to specific machine conditions and operational requirements.
