Installing the Oxygen Sensor

The GPR-1500-A Oxygen Transmitter is equipped with a SS sensor housing. This housing offers ease of

replacement of sensor and at the same time prevents any air leakage into the system. The two sections of

the sensor are held together by a metal clamp secured in place by easily accessed bolt. The integrity of the

sensor housing has been tested at the factory prior to shipment and is fully operational from the shipping

container.

Caution: All transmitters must be calibrated once the

installation has been completed and periodically thereafter

as described below. Following the initial installation and

calibration, allow the transmitters to stabilize for 12-24

hours and re-calibrate the transmitter with a certified span gas.

Caution: DO NOT dissect the oxygen sensor. The

sensor contains a corrosive liquid electrolyte that could

be harmful if touched or ingested, refer to the Material

Safety Data Sheet contained in the Owner’s Manual appendix. Avoid

contact with any liquid or crystal type powder in or around the sensor

or sensor housing, as either could be a form of electrolyte. Leaking

sensors should be disposed off in a manner similar to that of a

common battery in accordance with local regulations.

Avoid electrostatic discharge – Clean all surfaces with a

damp cloth only.

Procedure

1. Loosen the bolt at the bottom of the sensor housing by using 5/16 ranch provided.

2. Twist the upper section of the housing 90 degree and pull it up until it clears the bottom section of the

sensor housing.

3. Remove the old sensor (if previously installed) from the sensor housing

4. Remove the oxygen sensor from the bag and remove the two red shorting taps from the two ring gold

color contact plate of the sensor.

Remove the two red ribbons

from sensor PCB
