Product Overview
The Vibro-Meter CA202 144-202-000-116 is a shear-mode piezoelectric accelerometer engineered for continuous vibration monitoring in extreme high-temperature industrial environments. This passive vibration sensor generates charge output proportional to mechanical acceleration and requires an external charge amplifier to convert raw charge signals into standard voltage or current readings for DCS and vibration monitoring systems. It mitigates measurement drift and signal degradation common with standard accelerometers deployed near hot rotating equipment, delivering stable sensitivity of 100 pC/g with limited transverse interference. Vibration analysts, power plant maintenance teams and system integrators implementing predictive maintenance frameworks benefit from the fully welded, corrosion-resistant construction and extended thermal operating window. The integral armoured cable reduces wiring degradation, while mechanical shock resistance safeguards hardware integrity during transient equipment surges.
Application Scenarios
- Power Generation Gas & Steam Turbine Monitoring: Mounted on turbine casings and bearing housings to capture broadband vibration signatures. The wide temperature tolerance allows direct installation close to hot surfaces to detect early bearing wear, rotor imbalance and mechanical looseness before unplanned shutdowns.
- Oil & Gas Compressor Skid Condition Monitoring: Deployed on reciprocating and centrifugal compressors within hazardous facility zones. Sealed construction withstands exposure to process vapours, while charge output supports long cable runs between machinery and remote control rack signal conditioning hardware.
