Description
Temperature and/or humidity transmitter RedCos-D.. for hazardous locations
ATEX 2014/34/EU | Explosion-proof | Zone 2, 22
Combination with ExPro-C .. sensors
The RedCos-D transmitter with directly connected ExPro-C. sensors is a revolution for measuring temperature and/or humidity in HVAC systems, in chemical, pharmaceutical, industrial and offshore/on-shore installations, for use in explosive atmospheres Zone 2 (gas) and Zone 22 (dust Highest Protection class (ATEX) and IP66 protection, small dimensions, universal features and technical data guarantee safe operation, even under difficult environmental conditions.
All sensors are field-programmable without additional tools. The measurement ranges are scalable within the maximum ranges. The analog output signal is 0…10 VDC or (0)4. 20 mA and can be selected on site. The integrated display (can be switched off as required) is for parameterization and display of the actual value in operating mode.
