Digital Stem Position Encoder (SPe & SPe-HR)

The Stem Position Encoder (SPe) and SPe-HR (high resolution) version provide the valve tester with a convenient means to accurately measure valve stem position. The SPe version has a magnetic base and a variable orientation to allow the user to properly adapt to a variety of valve bodies and actuators. The SPe-HR uses a bracket to interface with AOV Travel Encoder Kits. Both SPe and SPe-HR provide a calibrated signal for input to the QL3/QL3.5-FS and FSQL Data Acquisition Systems. The Stem Position Encoder is available with 30- or 50-inch travel length.
