ETF 2 RS485 incl. stainless steel thermowell

Screw-in, immersion temperature sensor with RS485 output

Application
The ETF 2 RS485 is a screw-in temperature sensor in IP65 housing with quickrelease screws whose signal communicates via RS485 Modbus®-RTU and S-Bus. For recording the temperature of aggressive liquid and gaseous media. The application is in pipelines, in heating technology, in storage tanks, district heating compact stations, hot and cold water systems, oil and lubrication circuit systems, in machine, device and plant construction as well as in the entire industrial sector.
