Omnigrad - Model S TC66 -Explosion-proof TC Thermometer
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. Harsh environments, corrosive substances and highest pressures can be handled by the use of robust protection tubes and special materials. 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.
