4-20mA current loop noise sensorInstructions:
Working voltage: DC 24V stabilized power supply, working current 100mA (ripple<0.5%)
Load: 0 ohms -750 ohms (sufficient load margin, output can short-circuit)
Current loop mode output: 4 mA -20 mA
-----------------------------------------------------------------------------------
V+is connected to the positive pole O+and O - of a 24V power supply, and the output current loop is connected to the positive and negative poles. GND is connected to the negative pole of the power supply.
------------------------------------------------------------------------------------
Output algorithm: dB=(Io-4) * 100/16+30.
The noise value corresponding to a current of 15.2mA is (15.2-4) * 100/16+30=100dB.
