Vibro-meter’s comprehensive range of sensors and measurement chains can be used with our monitoring system hardware and software (or third-party systems) in order to provide complete solutions for the monitoring and protection of critical machines and processes.

From standard to harsh industrial environments, including hazardous areas and/or extreme temperatures (up to 700°C).

High temperature vibration sensors

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
– Qualified by major OEMs for industrial vibration monitoring.

The CE and SE series of accelerometers with integrated electronics have excellent low-frequency response (down to 0.2 Hz). The CE series of sensors are piezoelectric-based accelerometers that come with either attached electronics for higher temperature applications (up to 350°C) or integrated electronics for lower temperature applications (up to 120°C).

These sensors are suitable for the vibration monitoring in gas turbines, steam turbines, compressors, pumps, and fans. For applications that do not require the temperature capabilities of a CA sensor, this series provides a more cost-effective and easier to install solution.
