Description
The ExCos-P-... pressure 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 zone 1, 2 (gas) and zone 21, 22
(dust).
Highest protection class (ATEX) and IP66 protection, small dimensions,
universal functions and technical data guarantee safe operation even
under difficult environmental conditions.
All sensors are programmable on site without any additional tools. The
measuring ranges are scalable within the maximum ranges. At
...Cos-P-100 the smallest ∆P range is 20 Pa. The analogue output signal
is either 0...10 VDC or (0)4...20 mA and can be selected on site. The
integrated display is for parametrisation and an actual value indication
at working mode (can be switched off as needed).
...Cos-P-...-A sensors are equipped with an additional intrinsically
safe (IS) output, e. g. for an external indicator.
...Cos-P-...-OCT and ...-OVA offshore versions are equipped with stain-
less steel tubing Ø 6 mm.
