Installation instruction

This module connects with external part by adopting Pin1.25mm*8 single-row inserting pin, there are four

holes with 2mm diameters at the four corners, users fix the module through locations holes and make

connection through Pin1.25mm*8 wire.

Cautions

1 .Following conditions must be prohibited

1.1 Exposed to organic silicon steam

Sensing material will lose sensitivity and never recover if the sensor absorbs organic silicon steam.

Sensors must avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon

environment.

1.2 High Corrosive gas

If the sensors are exposed to high concentration corrosive gas (such as H

not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation.

1.3 Touch water

Sensitivity of the sensors will be reduced when spattered or dipped in water.

1.4 Freezing

Do avoid icing on sensor’s surface, otherwise sensing material will be broken and lost sensitivity.

2 . Following conditions must be avoided

2.1 Water Condensation

Indoor conditions, slight water condensation will influence sensors’ performance lightly. However, if

water condensation on sensors surface and keep a certain period, sensors’ sensitive will be decreased.

2.2 Used in high gas concentration

No matter the sensor is electrified or not, if it is placed in high gas concentration for long time, sensors

characteristic will be affected. If lighter gas sprays the sensor, it will cause extremely damage.

2.3 Long time storage

The sensors resistance will drift reversibly if it’s stored for long time without electrify, this drift is related

with storage conditions. Sensors should be stored in airproof bag without volatile silicon compound.

For the sensors with long time storage but no electrify, they need long galvanical aging time for

stability before using. The suggested aging time as follow:

Stable9.

Storage Time

Suggested aging time

Less than one month

No less than 48 hours

1 ~ 6 months

No less than 72 hours

More than six months

No less than 168 hours

2.4 Long time exposed to adverse environment
