SITRANS T measuring instruments for temperature
SITRANS T transmitters for mounting in sensor head
SITRANS TK/TK-H Two-wire system

Overview

The signal supplied by a resistance-based sensor (two, three or four-wire circuit) or a thermocouple element is amplified in the input stage. The voltage proportional to the input variable is then converted into digital signals in the analog/digital converter (1). These signals are forwarded electrically isolated (2) to the microprocessor (3). They are converted there in accordance with the sensor characteristic and further parameters (damping, ambient temperature etc.). The signal prepared in this way is converted in the digital/analog converter (4) into a load-independent direct current (4 to 20 mA). The power supply (5) is located in the output signal circuit. The SITRANS TK-H transmitter is parameterized and operated using a PC (6) connected to the two-wire line via the interface module for SIPROM software (HART modem, 7). A hand-held communicator can also be used for this purpose. The signals needed for communication in conformity with the HART r protocol V 5.7 are superimposed on the output current in accordance with the frequency shift keying (Frequency Shift Keying, FSK) method.
The smart solution The transmitter with the same capabilities as a SITRANS TK 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. The transmitter provides electrical isolation and enables the connection of resistance thermometers, resistance-based sensors, thermocouples and voltage-based sensors.

Application

SITRANS TK/TK-H temperature transmitters with "Non incendive" type protection can be mounted within potentially explosive atmospheres (zone 2). SITRANS TK/TK-H temperature transmitters with "Flame-proof enclosure" type protection can be mounted within potentially explosive atmospheres (zone 1).

Function

The SITRANS TK/TK-H temperature transmitter converts the signals from resistance thermometers, resistance-based sensors, thermocouples or voltage sensors into a load-independent direct current corresponding to the sensor characteristic. As a result of its compact design, the transmitter fits in the sensor head type B (DIN 43 729). The communication capability via the HART protocol V 5.x of the SITRANS TK-H permits parameterization using a PC or HART communicator (hand-held communicator). Parameterization is carried out using a PC for the programmable SITRANS TK-L. Mode of operation

The economical transmitter for Pt100 measurements The SITRANS TK-L dispenses with electrical isolation and universal sensor connection to provide a low-cost alternative for Pt100 measurements. SIPROM TK software is used in combination with the modem for SITRANS TK for the parameterization. A very compact design makes the SITRANS TK-L ideal for the retrofitting of measuring points or for the use of analog transmitters. The transmitter is available as a non-Ex version as well as for use in potentially explosive atmospheres.
