Description of BENTLY NEVADA 990-04-70-01-05


990-04-70-01-05


  • The Bently Nevada 990 Vibration Transmitter is designed to provide simple and effective vibration monitoring for industrial machinery. It delivers a proportional 4-20 mA output signal, which is ideal for integrating into machinery control systems. The device accepts input from Bently Nevada's 3300 NSv proximity probes and their corresponding extension cables.

  • Key features include a built-in proximitor sensor, eliminating the need for an external unit, and non-isolated output terminals for diagnostics. The transmitter offers incremental scale factor accuracy of 7.87 mV/µm, ensuring precise vibration amplitude measurements. Its temperature stability guarantees consistent performance within ±10% of the scale factor across a wide temperature range of 0°C to +70°C.

  • The frequency response of 5 Hz to 6,000 Hz ensures it can detect a broad range of vibration frequencies, making it suitable for various types of machinery. It also features a signal defeat circuit to prevent false alarms caused by faulty probes or loose connections, ensuring reliable fault detection. The easy mounting options, including DIN rail clips or bulkhead screws, simplify installation in diverse industrial environments. This transmitter is suitable for non-hazardous and Zone 2 or Div 2 hazardous locations, operating on a 28V DC power supply.
