K Controls New Valve Position Monitor
The 007-100 Exd IIC Position Monitor is ATEX and IECEx certified for use in gas Zones 1 and 2 and dust Zones 21 and 22. Gas certification varies with content and is typically Exd IIC T4 (T ambient -20°C to +80°C) or Exd IIC T6 (T ambient -20°C to +40°C). The ambient temperature limits can exceed those of other Exd products in the K Controls range. For example, there is a decrease in the lower limit from -50°C to -60°C and with 5 amp switches the upper limits increase from +40°C to +70°C at T6 and from +80°C to +120°C at T4. For explosive dust environments the product is certified Exd tb IIIC T135°C or Ex d tb IIIC T85°C.
The CE marked, IP67 enclosure is more compact than the existing 007-120 Exd IIC and is available in both coated aluminium or ANC 4B (316) stainless steel.
A single M20 conduit entry is standard. ½" NPT is an option together with the following dual conduit entry combinations: M20 + M20, M20 + M25, ½" NPT + ½" NPT or ½" NPT + 3/4" NPT.
Designed for use in the oil, gas and petrochemical industries the unit can be fitted to a wide range of quarter turn or linear valve actuators. It can also be fitted to the handles or gearboxes of manually operated valves.
The product has been designed to accommodate, as an option, the latest version of the top mounted highly visible Klearvision position indicator that can be used in IIC hazardous areas.
There is a very extensive range of monitoring equipment that can be fitted in this new 007-100 Exd IIC Position Monitor.
Switch options include one or two micro switches, hermetically sealed magnetically operated reed switches and standard or failsafe inductive proximity sensors. A solenoid back wiring facility can be provided so that switches and solenoid can be wired to the control room via a single multicore cable without the requirement for a separate junction box.
For continuous feedback of valve position or for monitoring the performance of critical emergency shutdown valves during partial stroke testing, 4-20mA, 4-20mA + HART®, PROFIBUS® PA or FOUNDATION™ FIELDBUS position transmitters are available.
