Application
ExCos-D... transducer ExPro-C... sensor
Description
The ExCos-D... transducer generation from together with direct coupled
ExPro-C... sensors are a revolution for measuring temperature and/or
humidity 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 dimension,
universal functions and technical data guarantee safe operation even
under difficult environmental conditions.
The measuring ranges are scalable within the maxium ranges. 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 actual value indication
which can be switched off.
All sensors are programmable on site without any additional tools.
ExCos-D-A transducer are additionally equipped with a (0)4...20 mA IS
(IS = intrinsically safe) output, e.g. for an external indicator.
