Omnigrad S TR66 Explosion-proof Pt100 Thermometer
Omnigrad S TR66 Explosion-proof Pt100 Thermometer
Safe monitoring of process temperatures in challenging applications e. g. in the Oil & Gas industry
Product Overview
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.
Benefits
-
Types of protection for use in hazardous locations: Intrinsic safety (Ex ia), 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
-
Fast response time with reduced/tapered tip form
-
High degree of flexibility thanks to modular design with standard terminal heads as per DIN EN 50446 and customer-specific immersion lengths
