Calculation of the output signal from "Characteristic value of the sensor" and measuring range of the measuring amplifier
When current output 4-20mA, the zero point is shifted to 4mA.
The maximum change of the output signal (the output signal swing) is 16mA.
The output increases by 16mA if the input sensitivity is modulated at 100%.
Sensor: 2,000mV / V 100N per
amplifier: 16mA per 2,000mV / V
- 2,000mV / V / 100,0N x 16mA / 2,000mV / V = 6,25N / mA
- 1mA (+ 4mA offset) corresponds therefore 6,25N
- 16mA (+ 4mA offset) corresponds therefore 100N
Hindweis: Even when measuring amplifiers with shifted zero, for example, 5V ± 5V measuring range for the output signal is stroke indicated.
