Description：

The CA134 is a high-temperature piezoelectricaccelerometer from Parker Meggitt's vibro-meterproduct line.

The CA134 sensor features a compression-modemeasuring element with internal case insulation in ahigh-temperature nickel alloy case (housing).

The CA134 is available as a sensor only or fitted withan integral mineral-insulated (MI) cable that isprotected by a double braid and terminated with avibro-meter high-temperature connector. Thesensor and cable are hermetically welded to producea sealed leaktight assembly. The sensor only versionallows different cable assemblies to be useddepending on the environmental/temperaturerequirements of the application.

All versions of the CA134 are Ex certified forinstallation in potentially explosive atmospheres(hazardous areas).

The piezoelectric material used and the design of theCA134 ensures an extremely stable and reliabledevice that is suitable for the long-term monitoringand measurement of vibration over wide temperatureranges in severe environments, such as gas turbinesor cryogenic applications.

Frequently asked questions

Q1: What is the Vibro-Meter CA134 144-134-000-612 Piezoelectric Accelerometer used for?

A1: The CA134 Piezoelectric Accelerometer is designed for vibration measurement and condition monitoring of rotating machinery. It helps detect mechanical issues such as imbalance, misalignment, looseness, and bearing defects in critical industrial equipment.

Q2: What is the overload capacity of the CA134 accelerometer?

A2: The CA134 sensor can withstand spike accelerations up to 1000 g peak, providing excellent protection against shock events and transient vibration conditions.

Q3: What is the CA134 continuous operating temperature range?

A3: The CA134 is designed for continuous operation from −54°C to +500°C (−65°F to +932°F), making it suitable for extremely high-temperature environments.

Q4: What is the transverse sensitivity of the CA134 sensor?

A4: The CA134 accelerometer has a transverse sensitivity of less than 5%, minimizing measurement errors caused by vibrations from directions other than the primary sensing axis.
