Function block diagram for SITRANS TH200/TH300

How the transmitter works

● The sensor supplies an electrical signal

①

● This signal is converted to a digital signal in an analog-to-digital converter

②

● The digital signal is evaluated in a secondary-side microcontroller

③

and corrected in

accordance with the sensor characteristic.

● The digital signal is transferred to the primary-side microcontroller

⑤

via the galvanic

isolation

④

● The analog output valve is calculated in the primary-side microcontroller

⑤

. The

functional status is indicated by LED

⑦

, and the communications data are prepared.

● The digital-to-analog converter

⑥

then converts the signal into an output current of 4 to

20 mA.

● The source of auxiliary power supply is located in the output signal circuit.
