Diff-Calc
Diff-Calc is applied for calculation of the difference between 4 - 20 mA signals from transmitters. Diff-Calc is especially designed for measurement of level differences where Diff-Calc is connected to two ultrasonic- or pressure level transmitters.
The two inputs and the output are for 4 - 20 mA, and the output is the difference between the two input signals. Diff-Calc is loop supplied from the input signals while the inputs must be supplied separately. To calculate the right difference, both inputs must have the same signal; e.g. 0 - 3 m VS at level measurement or 0 - 50 °C at temperature measurement.
