The Draeger Polytron 8200 CAT is an explosion-proof transmitter built to monitor flammable gases at LEL concentrations. Utilizing the catalytic bead DraegerSensor Ex … DD, it can detect a broad range of combustible gases and vapors. It offers a 3-wire 4 to 20 mA analog output, relay support, and digital communication through Modbus and Fieldbus for seamless system compatibility.
• Fast and stable – the DrägerSensor® Ex • Easy device management via digital communication • Same design, same operating principle • Three relays for controlling external equipment • Safe, robust housing for every application • Make the impossible possible with the remote sensor • Data logger
• Oil refineries/mining/OnShore/Off Shore /Water treatment Plant • Continous monitoring of Hydrocarbon , Hydrogen Flammable Gases using Catalytic technology • Measuement of Flammable inside the Duct upto 150degc ( Remote installation up to 30 meters Available) • Hazardous area Application (zone 1,Zone2) • Continous monitoring of Hygrogen in battery rooms
