Product Information

Brand: Bently Nevada

Model: 330800-16-00-039-03-02

Type: Vibration Sensor (Eddy Current Displacement Sensor)

Application System: Mainly used for vibration monitoring of rotating machinery such as steam turbines and compressors, it is a core component of the Bently Nevada 3300 series monitoring system.

core parameters

Measurement range: 0-250 μ m (peak to peak)

Sensitivity: 8V/mm (typical value)

Frequency response: 0-10kHz (suitable for high-frequency vibration monitoring)

Working temperature: -40 ℃ to+85 ℃ (suitable for harsh industrial environments)

Output signal: voltage signal (proportional to vibration displacement)

Power supply requirements: A preamplifier (such as 330180 series) is required to provide a -24V DC power supply.

Specification characteristics

Probe diameter: 8mm (standard size, suitable for most installation scenarios)

Probe length: 50mm (can be customized according to actual needs)

Cable type: coaxial cable (usually 5 or 9 meters in length, needs to be matched with a preamplifier interface)

Protection level: IP65 (dustproof and waterproof, suitable for industrial sites)

Material: The probe housing is made of stainless steel, and the cable is designed with low noise coaxial.

Usage scenarios

Turbine vibration monitoring:

Monitor the axial vibration of the turbine rotor to prevent faults such as bearing wear and rotor imbalance.

Typical applications: power plant steam turbines, gas turbines.

Compressor status monitoring:

Detect the vibration of the compressor rotor to avoid seal failure or mechanical damage caused by excessive vibration.

Typical application: Centrifugal compressors in the petrochemical industry.

Fan and pump equipment:

Monitor the vibration of the fan impeller and pump shaft to ensure stable operation of the equipment.

Key mechanical protection:

As an input for mechanical protection systems (such as Bently 3500 series), it triggers an alarm or shutdown signal.
