Bently Nevada 991-01-XX-01-05 284318-01 2-Wire Thrust Transmitter

FAQ

Q1. What is the main function of the 991-01-XX-01-05 transmitter?
It measures axial shaft displacement and converts the signal into a 4–20 mA output for monitoring and protection systems.

Q2. Which probes are compatible with this transmitter?
It is designed to work with Bently Nevada 3300 NSv proximity probes and matching extension cables.

Q3. What output signal does the transmitter provide?
It provides a standard 4–20 mA analog current loop proportional to shaft thrust or position.

Q4. What power supply is required for operation?
The transmitter operates with 12–35 VDC power.

Q5. What is the typical operating temperature range?
The device can operate between −40°C and +85°C, suitable for harsh industrial environments.

Q6. How is the transmitter mounted?
It can be mounted on a 35 mm DIN rail or panel inside a control cabinet.

Q7. What types of equipment commonly use this transmitter?
It is commonly used in centrifugal compressors, pumps, fans, motors, and turbines for axial thrust monitoring.

Q8. Why is axial thrust monitoring important in rotating machinery?
Monitoring thrust helps detect abnormal shaft movement early, preventing bearing damage and improving machinery reliability.
