·4-20mA output signal conversion calculation
For example, the range is 0~65535LUX, 4~20mA output, when the output signal is 12mA,
Calculate the current lighting value. This light range spans 65535 lux with 16 mA current
Signal to express, 65535 degrees / 16mA = 4095.9375 LUX / mA, that is, current 1mA
Represents illuminance change 4095.9375LUX. Measured value 12mA-4mA=8mA.
8mA*4095.9375LUX/mA=32767.5LUX. 32767.5+(-0)=
32767.5LUX, the current illuminance is 32767.5LUX.
The calculation formula is:
Light = 4095.9375 * current -16383.75, current value unit mA (range 0-65535Lux)
Light = 12500 * current -50000, current value unit mA (range 0-20 million Lux)
·0-10V output signal conversion calculation
For example, the range is 0~65535LUX, 0-10V output, when the output signal is 5V,
Calculate the current illuminance value. This light range spans 65535 LUX.
Expressed with a 10V voltage signal, 65535LUX/10V=6553.5LUX/V,
That is, the voltage 1V represents the illumination change of 6553.5 LUX. The measured value is 5V-0V=
5V.5V*6553.5/V=32767.5LUX. The current illuminance is 32767.5 LUX.
The calculation formula is:
Light = 6553.5 * voltage, voltage value unit V (range 0-65535Lux)
Light = 20000 * voltage, voltage value unit V (range 0-20 million Lux)
·0-5V output signal conversion calculation
For example, the range is 0~65535LUX, 0-5V output, when the output signal is 2V,
Calculate the current lighting value. This light range spans 65535 LUX.
Expressed with a 5V voltage signal, 65535LUX/5V=13107LUX/V,
That is, the voltage 1V represents the change in illuminance 13107LUX. The measured value is 2V-0V=
2V*13107LUX/V=26214LUX. The current illumination is 26214LUX.
