Connecting Pressure Sensor to DEWE43A

Hello,

I am trying to connect STW pressure sensor on DEWE43a.

Attached sensor information

I am using the same connection mentioned in one other forum topic.

Also I am using Differential input type

but i am not seeing any pressure change.

Would appreciate any help.

Dear Karansinh,

I have checked the attached drawing and basically, it is done correctly but the pins can be confused because the lines are drawn over the incorrect ones.

Please recheck the wiring:

If you measure between Pin1 and Pin4 you should get 5V of excitation. The SNS line regulates the excitation so it is a stable 5V.

Please note that the +/- 5V on Dewe-43 has a 70mA current limit:

Best regards,

Rok
