 I need advise on the followings:

1. I am using a Kistler make piezoelectric pressure sensor with charged amplifier, using NI module 9223 as the sensor output is in volts. Sensor has three wires  - Output (1 wire) and power (2 wires); and requires 12 volt supply. I do not know how to obtain pressure data from this arrangement.

Have you read the Kistler manual? If anything is unclear, I suggest you contact Kistler support first.

Please provide some more information on your sensor and signal conditioner (charge-amplifier) Model name and/or link to datasheet would be helpful.

Thanks Henrik.

The pressure sensor is Kistler 6613CQ09. The charged amplifier provides three wires - 1 signal, 1 power and 1 ground. The signal is voltage type.

I will connect signal to NI 9223 and power and ground to 12 V supply. Sensitivity of sensor is 25 mV/bar.

I understand the cDAQ will give output in mV and requires to converted into pressure. This conversion I am not clear about.

Thanks. I have attached the sensor's data sheet for your reference.
