Piezoelectric industrial velocity sensor, straight exit

The CMSS 793V is a precision velocity sensor mainly for use in the following industries:

• Oil and Gas
• Reining
• Petrochemicals
• Power Generation

Corporate standards and practices in these industries often require the use of velocity transducers, and piezoelectric devices such as the CMSS 793V eliminate the moving parts associated with self-generating velocity sensors (which will lead to degradation over time) The CMSS 793V is an accelerometer with internal integration electronics in order to provide velocity as an output

This series of sensor is one of the most long-standing models from SKF, with over 25 years of installed experience, together with a long track record of proven reliability It is recommended for use when the vibration signal is to be used for machinery protection applications, where a higher precision may be required Common applications would include API 670 standard monitoring of pumps, fans and compressors
