More Information

The new ExCos-P...preassure sensor generation from +/- 100 Pa to +/- 7.500 Pa (acc. to type) is a revolution for differential pressure measuring in HVAC systems, in chemical, pharmaceutical, industrial and Offshore/Onshore plants, for use in hazardous areas zones 1, 2 (gas) and 21, 22 (dust). Highest protection class (ATEX) and IP66 protection, small dimension, universal functions and technical data guarantee safe operation even under difficult environmental conditions. The measuring ranges are scalable within the maximum ranges. At ExCos-P100 the smallest ΔP range is 20 Pa. The analogue output signal is either 0...10 VDC or 4...20 mA and can be selected on site. The integrated display is for actual value indication which can be switched off. All sensos are programmable on site without any additional tools. ExCos-P...-A sensors are additionally equipped with a 4...20 mA IS (IS = intrinsecaly safe) output, e.g. for an external indicator. ExCos-P-..-OCT is Equipped with stainless steel 316L tubing ø 6 mm.
