Dimensions( mm )
The STK135 can be operated in the following ways:
Using the three keys above the instrument directly at the mounting point
for calibrating zero point and span at the touch of a button.
Or
Operating remotely using the HART protocol
-e.g. via HARTTalker and a PC with the SENSE operating programm HART Tran
Operation of push buttons
The STK135 can be programmed via three buttons.
Following parameters can be adjusted: scaling, decimal point, damping, display model, fix output current, and reset.
HART-commnication via HART-protocol the possibility of setting zero and span value is given.
HART-communicatin, which can run via PC, note-book, PDA, measured values and parameters become transparent and
are available on every step of the signal circuit.
