The V200EX-GA is referred to as an “Explosion Proof” unit. It has a pre-calibrated external EX rated IP converter with the special approval for using gas as the operating medium mounted directly to the V200P base positioner by a short adaptor plate.

The IP converter uses the actual supply air pressure from the positioner filtered through a specially designed filter. The IP converter then converts this pressure via an electrical signal to a
20-100kPa / 3-15psi signal back into the positioner diaphragm chamber for mechanical positioner response.

The V200EX-GA is a two wire 4-20mA instrument and is available for use on rotary or linear applications. It utilizes a unique spool valve, is a cam characterized, forced balanced instrument that is simple and rugged. With a rugged IP66 / NEMA 4X die cast aluminum housing and an electrostatically applied polyester coating the unit has an excellent protection against a wide range of environmental conditions.

Standard features like the external zero and span adjustment makes this positioner very user friendly for calibration and maintenance. The large indicator has scaling to operate in both direct and reverse directions. With the unique snap in drive shaft design the unit can be used for versatile mounting to various actuator applications. The gauge block is cast into the housing and therefore standard. Options like special cams, dome indicators and more are available.

Please note: The EX-GA approval is only referring to the IP converter. Gas as operating media can have limitations of materials in the positioner that needs to be verified.
The use of gas as operating medium does also require verification of the uncontrolled bleed. We recommend the use of the V200 Sealed and Ventilated as the base positioner as all bleed out from the positioner is lead to one OUT-port – The IP converter bleed is lead to a port on the IP it self.
