Digital Stem Position Encoder (SPE)

The Stem Position Encoder (SPE) provides the valve tester with a convenient means to accurately measure valve stem position. This custom “string pot” has a magnetic base and a variable orientation to allow the user to properly adapt to a variety of valve bodies and actuators including MSIVs, AOVs and MOVs. The SPE provides a calibrated signal for input to the QUIKLOOK Data Acquisition Systems.
