  • Page 11: Description

    Description Field of application The SITRANS TH100 transmitter can be used in all fields. Its compact size means that it can be installed in connection heads of type B (DIN 43729) or larger. The following sensor can be connected: ● Pt100 resistance thermometer The output signal is a load-independent direct current of 4 to 20 mA which is proportional to the temperature.

  • Page 12: Nameplate Structure

    Information about explosion protection With explosion-proof devices, the information about explosion protection is noted on an additional plate on the enclosure. Information regarding the certified types of protection can be found in Chapter Technical data (Page 33): SITRANS TH100 Operating Instructions, 06/2010, A5E00331168-02...

  • Page 13: Mode Of Operation

    Figure 3-2 Function block diagram SITRANS TH100 Mode of operation of the transmitter The signal delivered by a Pt100 resistance thermometer (two-wire, three-wire, four-wire system) is amplified in the input stage. The voltage proportional to the input variable is then converted into digital signals by a multiplexer in an analog-to-digital converter.
