How to Read PH value by use PH sensor checking and Conductivity send Value to (CJ1W-AD081-V1 Omron) This circuit diagram for connect sensor (PH sensor) to conductivity and send data to CJ1W-AD081-V1 This is PH Sensor connect to conductivity This is AD081-V1 wire connect to conductivity Conductivity can read PH value from PH sensor show in display monitor but can't send PH value to AD081-V1 Omron Wiring in side Conductivity PLC Program for Ph control AD081V1 CIO 2060-2069 We use 6 Point

How about just looking up a wiring diagram of this specific transmitter type (which would be worth mentioning...) ? All but image 1 are absolutely useless...

Look on the back of the transmitter, note transmitter type, enter in Google. How can we check if your wiring is correct if we don't have any reference ? Besides, the photo of the AD081 doesn't tell us much. Make a diagram how you connected the sensor. When you have checked the wiring you should also check your settings of the AD081.

Is the model a Signet 8750-1? If it is, then it has only an open collector output. The reason there is no voltage at A/D is Signet does not produce any! See the following Sensors page 8750-1 manual.PDF

My model is Signet 8750-400-1 You mean Signet 8750-1? can't send voltage to A/D but Signet 8750-400-1 can send voltage or not

8750-1 does NOT send voltage. RTFM! Have a look at drawing, you need to add power supply
