Product Description
Gas sensor is a device that converts gas concentration information into weak electrical signals, and is the core of gas detector.
At the same time, the sensor is very sensitive and fragile. It needs to be carefully used and protected,
or it will cause performance degradation or damage. Therefore, the sensor is a worn out product.The following points should be noted during use:
1.The operating temperature of most electrochemical sensors is -20ºC ~ +50ºC, for infrared sensors is -40ºC ~ +70ºC, and the operating humidity is 15-95% RH(no condensation).Special sensor environment depends on specific model.
2.Ensure that the gas flowing into the sensor gas chamber does not contain impurities or stains, such as moisture and oil stains, which are easily attached to the sensor surface and cause sensor failure or damage.
3. The sensor is recommended to be calibrated every 3 months, depending on the field environment, such as whether there is often a large amount or a small amount of target detection gas in the field environment.
4. Electrochemical sensors have a service life about 2 years, and infrared sensors have a service life about 3 years. Special sensors depend on the specific model and field environment, whether the field environment temperature is too high or too low.
5. The sensor shall not be unplugged with electricity and shall not impact and fall;Its warranty terms are subject to the standards of sensor manufacturers, artificial damage or improper use, no warranty.
Note :
Please purchase and replace the sensor from our company. If the sensor is not approved by our company, the function and performance of the instrument may not meet the requirements of the design, or even the sensor or machine may be damaged.
Our company shall not be responsible for any loss caused thereby.

Product characteristics
fixed gas detection instrument (hereinafter referred to as the detector), through the sensor to collect the corresponding gas concentration, the target gas concentration is converted into the corresponding current or voltage signal and transmitted to the signal collection and processing circuit for filter amplifier and then to convert the AD module, eventually to CPU units for various operation, finally it is concluded that for the gas concentration, and the computing results for display and control of the corresponding unit module, for the various signal output and control.
This detector adopts the design scheme of instrument panel display interface and three-color backlight.Intuitive reading, failure and alarm indication;
The circuit board uses four layers of wiring, the craft is simple, use the flame-proof design; output signal can chose 4~20 mA RS485 0~5V 0~10V 200~1000Hz two sets of relay output;
It can be conveniently composed of safety protection system with DCS, PLC and ES90C series alarm host and central station software independently developed by our company.High detection sensitivity, fast reaction speed, strong anti-interference ability, stable and reliable performance, excellent signal processing algorithm, as the leading level products in China and abroad.
It can be widely used in metallurgical, petroleum, chemical, mining, coking, municipal, environmental protection, pharmaceutical, electric power, shipping, sewage treatment, laboratories, scientific research institutes and other places that need continuous testing of inflammable, explosive, toxic and harmful gases.
