Product summary - K4-20 Position Transmitter

Devices for monitoring the position of modulating control valves.

The K4-20 range generates an accurate 4-20mA signal to monitor the position of rotary or linear modulating control valves. This product is used either where a positioner is not required or where it is preferable to monitor position via a separate linkage. Ex ia and Ex d versions are available together with optional end of travel limit switches.
