Description：

The Bently Nevada 792414506-04 is an industrial vibration transmitter designed for monitoring the health of rotating machinery. It converts mechanical vibration measurements into a standardized electrical signal that can be incorporated directly into industrial monitoring and control systems.

For vibration measurement, the 792414506-04 provides a sensitivity of 100 mV/g and a frequency response from 10 Hz to 1 kHz. These characteristics enable the device to detect vibration generated by rotating machinery across the specified frequency range.

By combining a two-wire loop-powered configuration, 4–20 mA output, 100 mV/g sensitivity, 10 Hz to 1 kHz frequency response, -40°C to +85°C operating range, and a hermetically sealed stainless steel enclosure resistant to mechanical shock, corrosion, and electromagnetic interference, the Bently Nevada 792414506-04 Industrial Vibration Transmitter provides a rugged solution for continuous vibration monitoring of rotating machinery in heavy-duty industrial environments.

Frequently asked questions

What is the 792414506-04?

It is a 2-wire, non-contact eddy current vibration transmitter used to measure shaft vibration and displacement in rotating machinery.

What does the "-04" suffix stand for?

It typically denotes a specific calibration range, linear displacement span (e.g., 2mm or 4mm), or thread/cable length configuration.

Why is the output reading over 20mA (or pinned at maximum)?

The probe might be touching the target shaft, the sensor is incorrectly gapped too close, or there is a short circuit in the wiring

What is the standard output signal format?

It outputs a standard 4-20mA current loop signal proportional to the vibration level.

Product Applications

Power Industry: Primarily used in large and medium-sized steam turbines, water turbines, gas turbines, and large generator sets in power plants to monitor differential expansion, vibration, and relative displacement between the rotor and casing, preventing mechanical damage under harsh steam and high-temperature environments.

Petrochemical Industry: Used in key centrifugal compressors, pump sets, fans, and other core rotating equipment in oil refineries and chemical plants to achieve continuous automated shutdown mechanical protection.

Metallurgy and Heavy Industry: In large vibrating equipment such as steel mills and blast furnace fans, sensors accurately capture abnormal mechanical vibrations, preventing fatigue damage to equipment under harsh operating conditions.

Water Treatment and HVAC: Widely installed in large water pumps, industrial fans, intelligent production lines, and other logistics and conveying systems for routine health monitoring and predictive maintenance.
