SELF-DIAGNOSTIC VALVE POSITION MONITOR
5 May 2011
|
The Type 3738 electronic valve position monitor from SAMSON CONTROLS can be used on on/off valves across a wide range of applications and enables valve position monitors to be configured at the push of a button.
This robust, innovative device is a contactless, magneto resistive sensor system that works with a NAMUR signal in compliance with IEC 60947-5-6 and is powered by a two-wire supply. As a result, the valve position monitor can replace existing solenoid valves and limit switches without the time consuming process of changing wiring or signal levels. At the same time, it includes functions like self-tuning and diagnostics, which opens up a wide range of opportunities for control and asset management.
The supply air for the actuator is routed through bores at the bottom of the housing, making additional tubing unnecessary. This makes it suitable for integrated attachment, which facilitates mounting and guarantees exceptional ruggedness. The contactless position sensor makes adjustments as well as moving levers redundant.
