wiring a pressure transmitter into a NI DAQPad-6015

[andreapretorius]

I need to wire a pressure transmitter (a two wire one) into a NI DAQPad-6015, and then use this pressure transmitter to record pressures in a pipeline.  How do I wire the transmitter into the data logger?  From there, how do I actually log the data?

Hi Andrea,

Can you provide me with the specifications for your pressure transmitter?

Hi

It's a S-10, 0 to 40 bar, 4 to 20mA, 10 to 30V DC transmitter.

Hi Andrea,

I looked at this Pressure Transmitter it seems to be a WIKA S-10, I’m not familiar with how a pressure transducer works but something that I can tell you from the spec sheet is that: seems that you can have different versions of the sensor 2 wire, 3 wire and current or voltage output, I would suggest connecting your sensor in a voltage mode since the other way you will have to add a shunt resistor.

Most of the time those sensor have three wires, red, black and white, you will set your connection for differential where red goes to AI+, black to AI- and white to AI GND and taking into account that white is the ground. As long as you output does not exceed what we spec -/+ 10 volts, 6015

Let me know if it helps
