Coneectring 3-wire pressure sensor to DEWE 43A

Hello,

I am using 30psi Pressure sensor and having issue with connection:

Sensor Detail:

Specifications:

Material: Stainless steel

Voltage: DC 5V

Pressure: 30 psi

Thread Type: 1/8" NPT

30 psi

Input: 030 psi

Output: 0.5V~4.5V linear voltage output. 0 psi outputs 0.5V, 15psi outputs 2.5V, 30 psi outputs 4.5V.

Accuracy: within 2% of reading (full scale).

Thread: 1/8"27 NPT.

Wiring Connector: Water sealed quick disconnect. Mating connector is included.

Wiring: Red for +5V; Black for ground; Blue for signal output.

I am using following connections:

The sensor has following connector:

Hi,

DEWE 43 has fixed +/-5V excitation. In this case, we would suggest this wiring:

Red for +5V; Black for ground; Blue for signal output.

SNS+ in EXC + = +5V sensor supply (red) 

GND, IN- and GND together. (black) 

IN+ signal input (blue) 

SNS- and EXC- can stay disconnected.

Hi,

I am using a 3 pin connector and am still not able to read the pressure value

Hi,

could you send us the sensor datasheet?

Hello,

Please find attached Data sheet

Sensor: MT01

Voltage: 0.5V to 4.5V

Pressure: 0 bar to 250bar

Dear Karansinh,

I have replied on this topic: https://forum.dewesoft.com/hardware-discussions/dewesoft-instruments/connecting-pressure-sensor-to-dewe43a

Please let us know if the new wiring diagram helped.

Best regards.
