The 007-100 is a compact solution that can contain up to 2 switches or a 4-20mA position transmitter. The larger 007-120 can contain up to 4 switches and a 4-20mA position transmitter. Ambient temperature ranges have, where possible, been extended. Some AEx d and Explosion Proof versions can achieve -60oC to +70oC at T6 or -60oC to +120oC at T4. ...
There are many unmonitored manual and actuated isolating valves in industrial process plants, where a cable run from the control room is not available and would be too costly or disruptive to install. To solve this problem K Controls has entered into a partnership with Pepperl and Fuchs to develop the 007 K4-20 WirelessHART Valve Position Monitor to provide frequent, wireless updates about a valve's position and eliminate the need for time consuming and risky visual inspections. ...
007-100 Valve Position Monitors have been specified for use on actuated valves in the vessel stabilisation ballast tanks of a new floating, protection, storage and offloading vessel (FPSO). The majority of the position monitors contain end of travel reed proximity switches and some provide a 4-20mA with HART® signal. Klearvision visual indicators were specified for certain applications. ...
The 007-100 and 007-120 Exd IIC Position Monitors are ATEX and IECEx certified for use in gas Zones 1 and 2 and dust Zones 21 and 22. The CE marked, IP67 enclosures are supplied in either coated aluminium or ANC 4B (316) stainless steel. Metric and NPT cable entries up to M25 and ¾" are available....
ATEX and IECEx are both certification schemes for electrical equipment in hazardous areas but why are two systems needed?ATEX is accepted outside Europe to some degree but its prime objective is free trade within the EU. This is achieved by establishing a level of safety acceptable to all the European national authorities. IECEx on the other hand was designed as an ISO/IEC Type 5 Certification Scheme administered by a single third party....
K Controls has supplied a major UK refinery with 160 stainless steel position monitors for retrofitting to a variety of different rotary and linear valve actuators. This particular plant removes acid from petrol in order to make it suitable for vehicle use....
K Controls submersible valve position monitors have been ordered for installation on a new floating production unit (FPU) under construction for the Statoil Gjoa project in the North Sea. The semi-submersible vessel will operate in a water depth of 380 metres in the Norwegian North Sea area and will come on stream in 2010. ...
