LoRaWAN Ex d NDIR Flammable Gas Sensor

Notes: If a sensor has been kept in transport containers at temperatures below zero centigrade, leave it at 10∼35℃ for not less than one hour.* if the Sensor is intended to install outdoors, please use a rain guard to protect the sensor from rain and direct sunlight. Please contact us to buy this accessory.

• Place the sensor in the area to monitor the target gas concentration. Please always check the gas molecular weight v.s the air.

• Do not use a damaged sensor. It must be repaired only by personnel authorized by the manufacturer.

• Keep the sensor out of contact with aggressive substances, e.g., acidic environments, which can react with metals, and solvents, which may affect polymeric materials.

• Diffusion holes of the sensor should be protected against the ingress of sprayed liquid or waterdrops, buy using the Splash guard or Rain guard.

• The sensor is not intended to measure the target gas concentration contained in fluids.

• Correct measurement is provided when the ambient temperature changes not faster than 0.6℃/ min.

• Inspection and maintenance should be carried out by suitably trained personnel.

• Persons, who have studied this guide, must be briefed on safety precautions when operating electrical equipment intended for use in explosive areas in due course.

• When dealing with a cylinder containing a gas mixture under pressure, it is necessary to follow safety regulations.

• There is no risk of pollution or negative impact on human health. The sensor does not contain any harmful substances that may be released during its normal operation.
