Bently Nevada 31000-16-05-00-073-03-02 Proximity Probe

Bently Nevada 31000-16-05-00-073-03-02 Proximity Probe is a probe for rotating machinery condition monitoring produced by Bently Nevada. The following is an introduction to it from multiple aspects:

Features and Advantages

High-precision measurement: Using advanced sensing technology, it can accurately measure the displacement, vibration, eccentricity and other parameters of the rotating machinery shaft, providing accurate data support for the condition monitoring of the equipment.

High reliability: With good anti-interference ability, it can work stably in harsh industrial environments, such as high temperature, high humidity, strong electromagnetic interference, etc., to ensure the accuracy and reliability of the measurement results.

Multiple installation methods: Flexible design, support for multiple installation methods, can be selected according to different equipment structures and installation requirements, convenient for users to install and debug.

Long life design: The selection of high-quality materials and advanced manufacturing processes makes the probe have a long service life, reducing the cost of equipment maintenance and replacement.

Working principle

Eddy current effect: The probe contains a high-frequency oscillator and an induction coil. When the probe is close to a metal conductor (such as the shaft of a rotating machine), the alternating magnetic field generated by the high-frequency oscillator will generate eddy currents on the surface of the metal conductor, and the eddy currents will generate a magnetic field in the opposite direction of the original magnetic field, thereby changing the inductance of the induction coil. By measuring the change in inductance, the distance between the probe and the metal conductor can be calculated, and then the displacement, vibration and other parameters of the shaft can be obtained.

Signal processing and transmission: The probe converts the measured inductance change signal into a voltage or current signal and transmits it to the monitoring system through a cable. The monitoring system amplifies, filters, analyzes and processes the signal, and finally obtains the operating status parameters of the equipment, and performs operations such as display, recording and alarm.

Application field

Power industry: used for status monitoring of rotating equipment such as generators, steam turbines, and fans, timely discovering equipment failure hazards, and ensuring the safe and stable operation of power equipment.

Petrochemical industry: widely used in compressors, pumps, centrifuges and other equipment, helping enterprises to achieve preventive maintenance of equipment, reduce downtime and improve production efficiency.

Metallurgical industry: It can monitor rolling mills, blast furnace blowers, steelmaking converters and other equipment to provide a scientific basis for equipment maintenance and management, reduce equipment failure rates, and improve product quality.

Other industries: Rotating machinery equipment in industries such as papermaking, cement, and mining also often use this probe for status monitoring to ensure the normal operation of the equipment and reduce maintenance costs.
