TURCK, represented in Australia by Micromax , has released the Vprox 773 valve position sensors.
The sensor is designed for use in the hazardous areas found in many processing and manufacturing applications. They are available with a potted-in cable or quick disconnect which allows faster, more reliable installations.
It is a two-wire ac/dc 20V-250V ac or 10V-300V dc) inductive proximity sensor with FM approval for use in Class 1, Division 2 hazardous location placement. It has a NEMA 4, 4X and 6 environmental rating. The 316 stainless steel housing is ideal for the harsh chemical environments often found in these types of applications.
The Vprox 773 has dual power (green) and switching (red) LEDs, which allow for easy sensor to target adjustment without the use of a meter. Since the Vprox 773 uses inductive technology, it has no moving parts that can wear, jam or break. This results in lower maintenance costs.
The sensor has a 15.875mm thread that will fit most industry standard valve brackets. It has a programmable output (normally open or normally closed) that is suitable for both valve and damper applications.
