© Siemens AG 2016 Temperature Measurement Transmitters for mounting in sensor head SITRANS TH400 fieldbus transmitter ■ Overview ■ Application • Linearized temperature measurement with resistance thermometers or thermal elements • Differential, mean-value or redundant temperature measurement with resistance thermometers or thermal elements • Linear resistance and bipolar millivolt measurements • Differential, mean-value or redundant resistance and bipolar millivolt measurements 2 ■ Function Features • Mounting in connection head, type B, to DIN 43729, or larger • Polarity-neutral bus connection • 24-bit analog-digital converter for high resolution • Electrically isolated • Intrinsically-safe version for use in potentially explosive areas • Special characteristic • Sensor redundance SITRANS TH400 fieldbus transmitters Versions: • For FOUNDATION fieldbus • For PROFIBUS PA With PROFIBUS PA communication • Function blocks: 2 x analog The SITRANS TH400 temperature transmitter is a small field bus transmitter for mounting in the connection head of form B. Extensive functionality enables the temperature transmitter to be precisely adapted to the plant’s requirements. Operation is very simple in spite of the numerous setting options. Thanks to its universal concept it can be used in all industries and is easy to integrate in the context of Totally Integrated Automation applications. Transmitters of the "intrinsically safe" type of protection can be installed within potentially explosive atmospheres. The devices comply with the Directive 2014/34/EU (ATEX), as well as FM and CSA regulations. With FOUNDATION fieldbus communication • Function blocks: 2 x analog and 1 x PID • Functionality: Basic or LAS Mode of operation The following function diagram explains the mode of operation of the transmitter. The only difference between the two versions of the SITRANS TH400 (7NG3214-... and 7NG3215-...) is the type of fieldbus protocol used (PROFIBUS PA or FOUNDATION fieldbus). Installing SITRANS TH400 in temperature sensors turns them into complete, bus-capable measuring points; compact - and in a single device.
