Safe and accurate measurement with the Schischek ExCos-D transmitter
The Schischek ExCos-D explosion-proof analog transmitter is specifically designed for the safe and accurate measurement of temperature and/or humidity in hazardous areas within ATEX zones 1, 2, 21 and 22. This versatile transmitter operates in combination with Schischek ExPro-C sensors, providing optimal performance for applications in HVAC systems, pharmaceutical facilities, chemical industries, and offshore/onshore environments.
Thanks to its universal power supply (24 VAC/DC) and selectable analog output signals (0…10 V / (0)4…20 mA), you can flexibly integrate this transmitter into your installation. The integrated Ex-e terminal box eliminates the need for additional Ex-i modules and intrinsically safe wiring. Additionally, you can easily set all parameters on-site, without additional tools or measuring equipment. Furthermore, the illuminated and switchable display ensures optimal readability of real-time values.
