TURCK MS 21-12EX0-R SPEED MONITOR MS2112EX0R

Description:

The TURCK MS21-12EX0-R Speed Monitor is used in hazardous area speed monitoring systems for detecting overspeed and under speed conditions from rotating equipment and machinery. Commonly installed in pumps, turbines, conveyors, mixers, compressors, and rotating process equipment operating in hazardous industrial environments. Maintenance teams and system integrators use this part for replacement, retrofit, machine protection upgrades, and hazardous area monitoring applications. 

Applications:

The TURCK MS21-12EX0-R Speed Monitor is commonly used in refinery process controls, chemical processing systems, conveyor systems, turbine monitoring applications, pump protection systems, and PLC or DCS control panels that require intrinsically safe rotational speed monitoring and overspeed or under speed protection functions for hazardous area equipment.
