scope of application

SITRANS TH200 and SITRANS TH300 transmitters can be used in all industries. Their compact size means that they can be installed in connection heads of type B (DIN 43729) or larger. Their universal input stage means that the following sensor and signal sources can be connected:

* Resistance thermometer

* Thermocouples

* Resistance-type transmitter/potentiometer

* DC voltage sources

mode of operation

The measurement signal sent by a resistance-type transmitter (two-wire, three-wire or four-wire connection) or thermocouple is converted into a digital signal in an analog-to-diigital converter. This signal is then evaluated in a microcontroller (μC1), corrected in accordance with the sensor characteristic and transmitted to the microcontroller (μC2) via the electrical isolation. There, the analog output value is calculated, the functional status is indicated by LED and the communications data is prepared. The measured value is converted into an output current of 4 to 20 mA by a digital-to-analog converter. The auxiliary power source is located in the output signal circuit.

The parameters of the SITRANS TH200 and the SITRANS TH300 are set and the devices are operated via a PC that is connected to the two-wire line via a suitable coupling module (SIPROM T modem or HART modem). Equally, the parameters of the SITRANS TH300 can be set with a HART communicator. The signals needed for communication using the HART protocol rev. 5.9 are superimposed on the output current in accordance with the frequency shift keying (FSK) process. The data specific to the transmitter and the data for parameter assignment is stored in two non-volatile memories (EEPROMs).
