بنگل نوادا 990-05-70-02-00

Product Features

Bently Nevada 990-05-70-02-00 has an integrated design with a built-in Proximitor sensor, eliminating the need for an external unit and simplifying installation.

Bently Nevada 990-05-70-02-00 allows diagnostics and signal output, and its non-isolated “PROX OUT” terminals and coaxial connectors provide dynamic vibration and gap voltage signals to support troubleshooting (isolation required with test adapter).

Bently Nevada 990-05-70-02-00 has a loop adjustment function, and the non-interacting zero and range potentiometers under its tabs support loop signal calibration.

Bently Nevada 990-05-70-02-00 is equipped with test input pins for quick verification of the loop output signal with a function generator.

Bently Nevada 990-05-70-02-00 is applause-protected, with “Not OK/Signal Defeat” circuitry preventing high outputs or false alarms due to probe failure or loose connections.

The potting construction supports 100% condensing humidity environments, and Bently Nevada 990-05-70-02-00 is designed to withstand harsh operating conditions.

Bently Nevada 990-05-70-02-00 offers mounting flexibility and comes standard with thru-plate screws (model 02) for fixed mounting requirements.

Product Using Principle

Signal Acquisition:

Bently Nevada 990-05-70-02-00 reads the vibration from the machinery through the 3300 NSv prox probe (using the eddy current principle that tracks the gap distance between the probe and it target) and transfer it to the transmitter on an extension cable.

Signal processing:

Bently Nevada 990-05-70-02-00 conditions the signal and scales the output in engineering units of peak-to-peak vibration amplitude (0-5 mils pp = 0-125 μm pp).

Signal Output:

Bently Nevada 990-05-70-02-00 is converted the vibration amplitude as into a 4~20 mA signal (4 mA for zero vibration, 20 mA the configured full scale), which is fed to the controlled system for VIB monitoring, Alarm and logic control.

Diagnostic support:

“PROX OUT” terminal outputs dynamic vibration and gap voltage signals that need to be isolated by the 990/991 Test Adapter (122115-01) and then be connected to an oscilloscope or other equipment for troubleshooting.
