ETF 1 incl. nickel-plated brass thermowell
Screw-in/immersion temperature sensor, with passive output
Application
The ETF 1 is a screw-in temperature sensor in IP65 housing with quick release screws. For recording the temperature of liquid and gaseous media. They are used 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. For aggressive media, use the stainless steel 1.4571 thermowells!
