 Core Electrical Parameters
Sensitivity: 100 mV/g (10.2 mV/(m/s²)), accuracy ±5%
Measurement range: 50g (peak value)
Frequency response: 10Hz～15kHz, suitable for gear meshing, bearing fault high-frequency vibration detection
Power supply voltage: -24VDC three-wire supply
Operating temperature: -55℃ ～ +121℃
Shell isolation grounding, resistant to on-site electromagnetic interference
Linearity: ±1% within full scale range

Typical Application Scenarios
Steam turbine, compressor, fan, gearbox, pump bearing housing vibration monitoring
High-frequency fault diagnosis of gear meshing, bearing pitting, blade vibration, etc.
Compatible with Bently 3500 vibration monitoring system, using 3500/42 acceleration monitoring module
Explosion-proof high-risk industrial sites in petroleum, chemical, thermal power, metallurgy, etc.

 Cable Requirements for Accessories
Standard sensor end is a 3-pin aviation thread connector. It is necessary to select Bently dedicated three-core shielded acceleration cable. The two ends of the cable should be matched with the aviation head of the sensor and the terminal of the monitoring module. It is not allowed to replace it with an eddy current probe cable.
