After Zero and Span, you will get the voltage output correspond to zero gas and span gas value;
Enter these values into your reading device (PLC...) to get correct reading.
- Place the sensor in the area to monitor the target gas concentration. Please always check the gas molecular weight
v.s the air.
- For example, NH3 gas has a lighter weight than air, so the sensor must be placed at a height higher than the source
of NH3 leakage. Normally, the sensor will be mounted at a height of 1.6m from the ground.
Use the M12-Male cable Coding A, 4 pin as below picture.
Because the Output is 0-10VDC, we do recommend to use the following cable for extention:
Cable size: minimum 24AWG (or minimum 0.5 mm2 core)
Cable type: Shielded
Max recommended cable legnth: 20m
Connect the wires to Reading device as below:
PWR+: 12-36VDC
PWR-: GND
OUT: 0-10VDC OUTPUT
NC: Not used
Step 3: Entering values to reading device
3. Installation
Notes:
* Avoid the place with humidity higher than 90% RH all the time (a short time in 2-3 days is acceptable)
* if the Sensor is intended to install outdoors, please use a rain guard to protect the sensor from rain and direct
sunlight. Please
