The CA134 144-134-000-612 is a high-temperature piezoelectric accelerometer from Parker Meggitt’s vibro-meter® product line.
The CA134 144-134-000-612 sensor features a compression-mode measuring element with internal case insulation in a high-temperature nickel alloy case (housing).
The CA134 144-134-000-612 is available as a sensor only or fitted with an integral mineral-insulated (MI) cable that is protected by a double braid and terminated with a vibro-meter® high-temperature connector. The sensor and cable are hermetically welded to produce a sealed leaktight assembly. The sensor only version allows different cable assemblies to be used depending on the environmental/temperature requirements of the application.
All versions of the CA134 144-134-000-612 are Ex certified for installation in potentially explosive atmospheres (hazardous areas).
The piezoelectric material used and the design of the CA134 144-134-000-612 ensures an extremely stable and reliable device that is suitable for the long-term monitoring and measurement of vibration over wide temperature ranges in severe environments, such as gas turbines or cryogenic applications.
