The new Type 3738 Electronic Valve Position Monitor (photo) can be used on on/off valves in all fields of application. The device indicates the end positions and controls the actuators. The position monitor features a contactless, magneto-restrictive sensor system and an integrated microprocessor, and can be configured at the push of a button. It operates using a Namur signal in compliance with IEC 60947-5-6 and is powered by a two-wire supply. As a result, the position monitor can replace solenoid valves and limit switches without having to change the wiring or signal levels. Other functions include self-tuning and diagnostics. — Samson AG, Frankfurt, Germany
