SPECIFICATIONS

Part No.: 3500/42M
Manufacturer: Bently Nevada
Product Type: Proximitor Seismic Monitor
Series: Bently Nevada 3500

3500/42M is a Proximitor Seismic Monitor component developed by Bently Nevada. It's a four-channel monitor with proximity and seismic transducer input. It compares the conditioned signals to user-programmable alarms and conditions the signal to produce vibration and location readings. The 3500 Rack Configuration Software can be used to program each channel to monitor and report radial vibration, thrust position, REBAM, acceleration, differential expansion, eccentricity, velocity, and other parameters.

  • The monitor channels are set up in pairs and can execute up to two of the functions specified at the same time. Channels 1 and 2 can, for example, perform one function while Channels 3 and 4 perform another or the same.
  • The Proximitor Seismic Monitor protects machinery by comparing monitored parameters to selected alarm setpoints in real-time, triggering alarms. It informs both operations and maintenance employees about critical machine information.
  • Depending on the arrangement, each channel typically conditions its input signal to yield a set of static values. It is possible to establish alert setpoints for any current static value, as well as danger setpoints for any two of them.
  • Set alarm levels for any value measured by the monitor and danger setpoints for any two of the values measured by the Monitor using Rack Configuration Software. For each measured value, alarms can be set from 0 to 100% of full scale. When the full-scale range exceeds the transducer's range, the setpoint is limited by the transducer's range.

Technical Characteristics

Inputs

  • Accepts signals from one to four proximity, acceleration, or velocity transducers.
  • Power Consumption of 7.7 watts.

Outputs

  • When the Monitor module is working properly, the OK LED lights on.
  • When the Seismic Monitor module is connecting with other modules in the 3500 rack, the TX/RX LED lights.
