Omnigrad - Model S TC88 -Modular thermometer
Comprehensive and common temperature measurement technology for almost all branches of industry. The high modular and robust thermometer finds its use in several applications in almost all industries, and is perfectly suited for use in the Chemical and Food & Beverages industry. 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. A variety of process connections, dimensions and materials offer flexible application possibilities.
-
High degree of flexibility thanks to modular design with standard terminal heads as per DIN EN 50446 and customer-specific immersion lengths
-
Variable total length in suitable thermowells thanks to compression fitting on extension neck
-
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™
