Instruction Manual
1 Technical Description
1.1 Area of Application
The SITRANS TK transmitter can be used in all branches of industry. Thanks to its
compact size, it can be installed in the type B or larger terminal housing
(DIN 43729). Thanks to ist universal input stage, the following sensors/signal
sources can be connected:
D Resistance thermometers
D Thermocouples
D Resistance-based sensors/potentiometers
D DC voltage sources
The output signal is an impressed direct current from 4 to 20 mA that corresponds
to the sensor characteristic.
Transmitters belonging to the "type of protection: Non incendive" type can be
installed in explosion hazard areas (Zone 2). Transmitters of type "intrinsically safe
type of protection" can be installed in explosion hazard areas (zone 1). The con-
formity certificates correspond to the European standard (CENELEC).
1.2 Product feature
D Two-wire transmitter
D Can be installed in a terminal housing type B or larger (DIN 43729)
D Capable of communication (HART protocol V 5.7 in the case of TK-H,
proprietary protocol in the case of TK); the sensor, the measurement range and
many other parameters are therefore programmable.
D Electrical isolation (500 V AC)
D Intrinsically safe type for use in hazardous areas
D Two additional taps for multimeter connection allow measurement of the current
signal without interrupting the loop.
