Omnigrad T TST41N - Modular RTD thermometer
The thermometer is mainly used in the chemical industry but also finds its use in other branches.
The device with head transmitter is a complete unit ready for use with enhanced measurement
accuracy and reliability compared to directly wired sensors. A variety of process connections,
dimensions and materials offer flexible application possibilities.
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
-
Fast response time with reduced/tapered tip form
-
Head transmitter with easy selection: Analog output 4 to 20 mA, HART®,
PROFIBUS® PA or FOUNDATION Fieldbus™
Field of application
The TST41N RTD thermometer is a general purpose assembly suitable for liquids and gases.
