Description

The limit value transmitters of Types 07-31..-.../... are deployed in conjunction with pneumatic actuators on valves and fittings. They serve to signal the "open/closed" status of a fitting. This end position is communicated by means of up to a maximum of 6 limit switches in the “Ex d” type of protection or by means of 6 proximity initiators in conformance to NAMUR in the “Ex i” type of protection. In intrinsically safe proximity initiators there is a choice of slot initiators or V3 initiators. The limit monitors are available in polyester, aluminium and stainless steel. The metal versions can be used in temperatures down to -60 °C – depending on the fitted components. To ensure mechanical adaptability to the pneumatic actuators, we supply 4 consoles according to VDI/VDE 3845. The BARTEC limit monitors can be used in hazardous (potentially explosive) areas in Zone 1 and 2 in accordance with the certified explosion sub-groups IIA, IIB and IIC and the temperature classes T5/T6 and in Zone 21 and 22 in accordance with the certified max. surface temperature.
