Product Features
Bently Nevada 190501-12-00-04 is capable of low-frequency vibration measurements, designed for low-speed (≥90 rpm) equipment. It captures vibration signals from fan assemblies, motors and gearboxes, reflecting rotor faults (e.g., unbalance, misalignment).
Bently Nevada 190501-12-00-04 can output an electrical signal proportional to the vibration speed, compatible with vibration monitoring systems, providing data support for equipment protection and diagnosis.
Bently Nevada 190501-12-00-04 supports a wide range of mounting adapters for different thread sizes, and a quick-disconnect kit to keep the cable connected when the sensor is removed.
Bently Nevada 190501-12-00-04 is resistant to extreme temperatures, humidity and shock, and is suitable for harsh industrial environments.
Bently Nevada 190501-12-00-04 is interference-resistant, with internal electronics isolated from the housing and lateral response <5% of axial sensitivity, reducing the impact of external interference on measurements.
Product Applications
Cooling tower fan assembly:
Bently Nevada 190501-12-00-04 monitors the vibration status of low-speed fans, preventing failures due to imbalance, bearing wear and so on.
Air-cooled heat exchanger:
Bently Nevada 190501-12-00-04 can be used for vibration monitoring of its fan and drive motor to guarantee the stable operation of the heat exchanger system.
Industrial low-speed rotating equipment:
Bently Nevada 190501-12-00-04 can be used for vibration protection and diagnosis of other rotating machinery (e.g., small motors and speed reducers) with a speed of ≥90 rpm.
Harsh environment places:
Bently Nevada 190501-12-00-04 is resistant to high and low temperatures, high humidity and shock, and can be used in outdoor, chemical, electric power and other industrial environments.
