The smart solution - The transmitter with the same capabilities as a SITRANS TH200 and a standardized HART interface.
This universal transmitter integrates your temperature measurement in the TIA concept (Totally Integrated Automation). This makes central engineering possible, bringing you time and cost benefits.
SIMATIC PDM or another HART programming tool can be used for the configuration.
Особенности
- Two-wire transmitter
- Assembly in connection head type B (DIN 43729) or larger, or on a standard DIN rail
- Communication-capable (HART protocol rev. 5.9 for SITRANS TH300, proprietary protocol for SITRANS TH200); this enables programming of sensor connection, measuring range, etc.
- Electrically isolated
- Intrinsically-safe version for use in potentially explosive areas
- Two additional test pins for connection of a multimeter support the measurement of the current signal without interrupting the current loop
- Operational status indication (LED green or red)
- Special characteristic
- Diagnostic functions with SITRANS TH300 (slave pointer, operating hours counter, simulation)
Область применения
The SITRANS TH200 and SITRANS TH300 transmitters can be used in all industries. Due to their compact size they can be installed in the connection head type B (DIN 43729) or larger. The following sensors/signal sources can be connected over their universal input module:
- Resistance thermometer
- Thermocouple elements
- Resistance-based sensors/potentiometers
- DC voltage sources
The output signal is a direct current from 4 to 20 mA in accordance with the sensor characteristic.
Transmitters of the "Intrinsically-safe" type of protection can be installed within potentially explosive atmospheres (zone 0). The declarations of conformity comply with the IEC standard.
Функции
Mode of operation
The signal output by a resistance-based sensor (two-wire, three-wire or four-wire system) or thermocouple is converted into a digital signal by an analog-to-digital converter. This is then evaluated in a microcontroller (μC1), corrected in accordance with the sensor characteristic and transmitted to the microcontroller (μC2) over the electrical isolation. There, the analog output value is calculated, the function status is determined over LED, and the communication data are preprocessed Over a digital/analog converter, the measured value is then converted to an output current of 4 to 20 mA. The power supply is located in the output signal circuit.
The SITRANS TH200 and SITRANS TH300 are parameterized and operated using a PC, which is connected to the two-wire system over a suitable interface module (SIPROM T modem or HART modem). A hand-held communicator can also be used to parameterize the SITRANS TH300. The signals required for communication according to the HART protocol rev. 5.9 are superimposed on the current signal in accordance with the FSK method (Frequency Shift Keying). The data specific to the transmitter and the data for parameterization are stored in two non-volatile memories (EEPROM).

The digital accuracy is the accuracy after the analog/digital conversion including linearization and calculation of the measured value.
An additional error is generated in the output current 4 to 20 mA as a result of the digital/analog conversion of 0.1% of the set span (digital-analog error).
The total error under reference conditions at the analog output is the sum from the digital error and the digital-analog error (poss. with the addition of cold junction errors in the case of thermocouple measurements).
