Introducing the Vibro-Meter CA202 Industrial Accelerometer
The CA202 144-202-000-206 piezoelectric accelerometer from Meggitt’s vibro-meter® line delivers reliable vibration monitoring. This robust sensor excels in harsh and hazardous industrial environments with its high sensitivity and durable construction. Oiltech Controls recommends this unit for critical measurement applications where performance matters most.
Primary Applications
- Continuous vibration monitoring on turbines, pumps, compressors, and fans.
- Condition-based maintenance programs in demanding industrial plants.
- Measurement in hazardous locations with potentially explosive atmospheres.
- Environments with exposure to steam, water, sea-salt, or corrosive agents.
Product Description
- The CA202 accelerometer uses a symmetrical shear-mode piezoelectric measuring element.
- Its design ensures internal case insulation and a differential charge output signal.
- The sensor comes with an integral low-noise cable for reliable signal integrity.
- A flexible, heat-resistant stainless-steel hose protects the cable along its entire length.
- This assembly is hermetically welded to create a permanently leaktight and robust sensor.
