Field of application
The robust thermometer is designed for use in demanding applications like gas or steam applications e.g. in the Chemical, Oil & Gas and Energy industry. Highest pressures as well as high temperature can be handled by the use of robust protection tubes and special process connections. 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.
Universal range of application
Particularly suitable for steam and gas applications with high process pressures and temperatures
Measuring range: -200 to +600 °C (-328 to 1112 °F)
Static pressure range up to 400 bar (5800 psi)
Degree of protection: up to IP68
Benefits
High degree of flexibility thanks to modular design with standard terminal heads as per DIN EN 50446 and customer-specific immersion lengths
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
Types of protection for use in hazardous locations: Intrinsic safety (Ex i.a.), non-sparking (Ex nA)
Head transmitter with easy selection: Analog output 4 to 20 mA, HART®, PROFIBUS® PA or FOUNDATION Fieldbus™
