This is Ali, with the University of Manitoba, Winnipeg, MB, Canada. We have Pressure sensors (Sensotec-FPG/C798 : 3000psig) in our laboratory. These sensors have 4 wires.
Would you please help me have an electrical schematic of the wiring? I am supposed to connect it to a DAQ board, and need to know which of these 4 wires (i.e. black, green, white, red) are ground, positive pole and negative pole? I found the following two wires are connected together:
- white and red,
- black (alone),
- green (alone).
which of them is ground? which is positive pole and which is negative pole? Do I have to connect the negative pole to the ground by means of a jumper while connecting it to DAQ board?
Thanks in advance.
