Functional Description
The 330500‑07‑02 sensor converts casing vibration into a proportional velocity signal using an internal piezoelectric accelerometer paired with onboard signal‑conditioning electronics. This architecture provides high sensitivity to low‑frequency vibration, making it suitable for machinery where casing vibration is the primary diagnostic indicator.
Its rugged housing and threaded mounting interface ensure secure installation in harsh industrial environments. The sensor’s low transverse sensitivity and stable output impedance support accurate readings even when exposed to mechanical stress or electrical noise.
Compliance with FCC Part 15 ensures the device operates without causing interference and remains resilient to external electromagnetic disturbances.
Application Scenarios
-
Turbine and compressor vibration monitoring
-
Pump and motor casing vibration measurement
-
Gearbox structural vibration analysis
-
General rotating machinery condition monitoring
