Vibro-meter’s CA series of sensors are high-temperature, piezoelectric-based accelerometers designed for the long-term measurement and monitoring of absolute vibration in the most severe of environments (up to 700°C).

An external signal conditioner is used to convert the sensor’s low-level pC/g output into a current or voltage signal suitable for transmission to the monitoring system. As a result, CA-based solutions enable high-performance at higher temperatures.

Key features
– Available in standard versions and in Ex versions certified for use in hazardous areas
– Finds application in high-temperature environments, safety-related applications using SIL 2 measurement chains
