| Supply voltage effect |
5V supply voltage effect: min.3V/max.5.5V
●For 0.5…4.5V output sensor, voltage has no effect for linearity and temperature compensation, voltage is proportional to LRV and FRV.
●For I2C and SPI digital output sensor, voltage has no effect for linearity, LRV, URV and compensation temperature.
24V supply power effect: min.9V/max30V
●For 4…20mA current output sensor, voltage has no effect for linearity, LRV, URV and compensation temperature.
