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).
