The HEF is a Hall Effect sensor which is compatible with the Aluminum, 303 Stainless Steel and 316 Stainless Steel body JV-CG and JV-KG series of flow meters. The sensor detects the rotation of the flow meter's gears and emits a frequency signal proportional to flow. The output signal is a square wave pulse which has a duty cycle of approximately 50%.
HEF signal outputs are protected with a self-resetting fuse. This fuse has a 50mA nominal trip point. When a trip occurs, turn off power to the sensor and remove output load to reset fuse.
The HEF sensor has two different output configurations: HEF-A or HEF-AA for a sinking output and HEF-B or HEF-BB for sourcing output. HEF-A and HEF-B are used with JVM-01CG through JVM-30CG, JVA-KG, JVM-KG & JVS-KG meters. HEF-AA and HEF-BB are used with JVM-60CG, JVA-60KG, JVM-60KG, JVS-60KG meters.
