3.Transmitter embedded two-wire passive 4-20mA intelligent digital display meter: SY LED2
SY LED2 digital display meter is used to measure DC current signal, and it can take power to measure on 4-20mAloop signal directly without external power supply,the displayed number is not the direct current measurement value, but the preset value of 4mAand 20mA, and the measured value is displayed linearly with respect to these two preset values. For example, 4mAis set to 0, 20mAis set to 1000, and 500 is displayed when 12mAis input. The maximum display range of the four digits of the digital display is 9999, and the minimum is -1999.
