More than 300 IP68 (sub-sea) K Controls Model 006 position transmitters have been specified for use in the Caspian Sea, at a depth of up to 135m. They are used to monitor the position of hydraulically actuated valves that flood the jackets on the legs of oil rigs. The K Controls 006 range of IP68 (sub-sea) valve actuator monitoring equipment has also recently been extended to include the options of a stainless steel enclosure and the possibility of ATEX 11 2 G EExia certification should the unit be required for intermittent submersion in a hazardous area. The standard unit is available in coated carbon steel and units are pressure tested to the depth equivalent of 15m. A standard M20 or 0.5’’ NPT conduit entry is provided or the base can be machined to accept a customer specified sub-sea connector. A variety of hermetically sealed solid state or reed style proximity switches can be fitted in the device together with 4-20mA, HART, Profibus or Foundation Fieldbus position transmitters.
