Omnigrad - Model S TC62 -Explosion-Proof Thermocouple Thermometer

FromEndress+Hauser Group Services AG

SHARE

Safe monitoring of process temperatures in challenging applications e. g. in the Oil & Gas industry. The robust thermometer is designed for use in demanding and safety relevant applications e.g. in the Chemical, Oil & Gas and Energy industry. The sensor is designed for use in a separate thermowell. An optional head transmitter with all common communication protocols makes the device ready to use with enhanced measurement accuracy and reliability compared to directly wired sensors. The modular design with a variety of options can be adapted to the measurement task.
