Use of different sensors with scc-sg24

[Pets65]

Hi,

in my application I've to use two type of sensors with following characteristics:

-a pressure sensor : 10V Ex V , input nominal 950 Ohm output nominal 300 Ohm

(what does it mean? I know that should be a 350ohm full bridge...)

-a load cel: 10V Ex V, 700Ohm full bridge

It is the SG24 able to read this kind of sensors?

Can I use a single SG24 module to read the two sensor using the two

channels at same time?

Thank you,

Pets

Hi Pets,

by looking at the scc-sg 24 specifications at this link http://www.ni.com/pdf/manuals/371073b.pdf you

you can see that your module has a 10 V excitation which is the same amount required by your sensor.

The module will work with either the 350 Ohm resistance and 700 Ohm, but since it's been designed for a 350 Ohm bridge, this will be more sensitive.

I hope this informations will help you.

Hi Ryan,

the sensitivity leak is not a problem.

But it is not clear if I can connect the two sensors at same time.

Thank you,

Hi Pets,

the SCC-SG 24 has two differential channels so you can connect the two sensors at the same time.
