NI 9219 maximum excitation voltage

[Jason_Chan]

Hi,

I would like to measure a load cell. Refer to load cell manual, the excitation voltage is 10 Volts and the output is 3 mV/V.

i am planning to use NI 9219 to measure the load. When I read NI 9219 manual, it say that the excitation voltage is 2.5V. I am not sure whether this is the maximum voltage.

1. Please advise wether NI 9219 can measure my load cell which require excitation voltage of 10Volts?

2. Besides, what is the maximum excitation voltage for NI 9219?

Thanks in advance,

Chan

Hello Chan,

In response to your question that is a maximum value and I'm affraid that this device is not going to work for you in order to measure the load, I have to say the 9219 doesn't support an external exitation so at the end I believe that the device is not going to wor for you. On the other side there is the 9237 that does support 10 V as an exitation voltage and also supports external exitation. Here you have the info about the 9237:
