990-08-XX-01-00, MOD: 165353-01 Vibration Transmitter

The Bently Nevada 2-Wire Vibration Transmitter (990-08-XX-01-00, MOD: 165353-01) is a device designed to measure vibration in industrial machinery, commonly used in industries like oil and gas, power generation, and manufacturing.

This transmitter works in conjunction with a proximity probe that is mounted on the monitored machine. The proximity probe measures the distance between itself and the machine’s surface, and this measurement is then used to calculate the vibration level. The transmitter subsequently sends a 4-20 mA output signal to a control system, allowing operators to monitor vibration levels and take corrective actions if necessary.

Key Features:

2-wire loop powered: Simplifies installation by using the same wiring for both power and signal.
4-20 mA output signal: Provides a proportional signal that can be easily integrated into industrial control systems.
Integrated Proximitor Sensor*: Built-in sensor for direct connection to proximity probes for accurate vibration measurements.
Non-isolated “PROX OUT” and “COM” terminals: These terminals facilitate easy connection with the proximity probe and the common line.
Non-interacting zero and span potentiometers: Allows for easy calibration without affecting each other.
Test Input pin: For performing functional or calibration tests on the unit.
Power-up Inhibit circuit: Prevents erroneous output signals during the power-up phase.
Not OK/Signal Defeat circuit: Enables the disabling or muting of signals when necessary.
Potted construction: Designed for high humidity environments to ensure durability and long-term reliability.
Compatible with 3300 NSv proximity probe: Ensures seamless operation with this widely used probe for vibration monitoring.

The 990-08-XX-01-00 (MOD: 165353-01) model is ideal for monitoring machinery such as motors, turbines, compressors, and other rotating equipment, ensuring that any issues with vibration are quickly detected and addressed to prevent further damage or downtime.
