MTS Sensors: Absolute Position Sensors for Process Control Valve Actuators

mts sensorsMTS Sensors can provide an absolute position sensor based on Temposonics® magnetostrictive technology that has no moving mechanical components and is wear free, calibration free and maintenance free.

This sensor uses a permanent magnet as the position marking element attached to a moving component of the actuator. Due to the nature of the magnetic field, position sensing can be detected through walls of non-ferrous materials such as aluminum or stainless steel.

Valve position feedback can be monitored by the process control plant software to detect valve malfunctions if preset positions are not reached. Valve monitoring is very important in processes, for example, where sludge buildup can obstruct valve closure. Preventive maintenance programs can be put in place for defined threshold valve characteristics before the entire system becomes critical and has to be taken out of production.

MTS Temposonics Sensors can produce a variety of output signals, analog or digital, that can be scaled into engineering units for process control. Fieldbus communication is also available.
