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.

• Heavy duty applications

• Oil & Gas processing industry

• Measuring range: –40 to 1 100 °C (–40 to 2 012 °F)

• Static pressure range up to 100 bar (1450 psi)

• Protection class: IP68

• Types of protection for use in hazardous locations: Intrinsic safety (Ex i.a.), flameproof (Ex d), non-sparking (Ex nA)

• High degree of insert compatibility and design as per DIN 43772

• Extension neck to protect the head transmitter from overheating

• High degree of flexibility thanks to modular design with standard terminal heads as per DIN EN 50446 and customer-specific immersion lengths
