Scaling Principle
Setting Example 1:
A measuring transducer transmitting a current signal of 4 mA to 20 mA is used as a transmitter. Currents well
below 4 mA indicate a transmitter failure; currents around 0 mA indicate a broken wire. A sensor detecting a
temperature is attached to the transmitter. The upper value corresponds to 200 °C and the lower value to
-100 °C. This results in the following characteristic. In accordance with the set characteristic curve, the func-
tion calculates the sensor value from the measured current. The coefficients of the linear equation (gradient
and foot point) are calculated from the set threshold and the sensor values are determined. A supplied current
of 9.333 mA corresponds to a temperature of 0 °C.
