Permissible media are gases, pressurized air and thin non aggressive media. As standard the offers a PNPcontact and a rotable display module. Additional features like e.g. an intrinsically safe version, max. contacts and an analogue output complete the profile. Preferred areas of use are Plant and Machine Engineereing Heating and Air Conditioning ISversion Ex ia = intrinsically safe for gases specific versions Laboratory Techniques
