485 noise sensor price

Industrial noise detection of 4-20mA current loop noise sensorperformance parameters

Working voltage: DC 24V stabilized power supply

Working current: 100mA (ripple<0.5%)<>

Wiring method: red wire to power supply, black wire to ground, green wire current output positive pole, blue wire current output negative pole.

Load: 250 euros to 750 euros

Output: 4 mA -20 mA

Output algorithm: dB=(Io-4) * 100/16 30. If the current is 15.2mA, the corresponding noise value (15.2-4) * 100/16 30=100dB

Industrial noise detection of 4-20mA current loop noise sensor

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
