Combustible gases are ubiquitous in industrial production and home life. Once they leak and reach a certain concentration, they can cause fires or even explosions. In order to ensure the safety of people's lives and property, combustible gas detectors came into being. As the core component of the combustible gas detector, the gas sensor undertakes the key task of monitoring the gas concentration. In view of the complex working environment of gas sensor, in order to ensure its stable operation and sensitive response, it is necessary to carry out temperature protection and temperature compensation by the NTC chip of EXSENSE Electronics to provide reliable technical support.

Gas sensor acts as the "radar" of the combustible gas detector, keenly detecting the combustible gas in the environment. The NTC chip assists the gas sensor to help the combustible gas detector work accurately. Specifically:

1. Stable temperature compensation

In the actual operation of gas sensor, the change of ambient temperature is one of the key factors affecting its performance. When the ambient temperature is abnormal (too high or too low), the output signal of the gas sensor may be skewed, resulting in the acquisition of incorrect gas concentration data. In this case, the NTC chip will cooperate with other components inside the gas sensor to adjust the circuit parameters to offset the effect of ambient temperature changes on the gas sensor output. The temperature compensation mechanism of the NTC chip greatly improves the reliability and accuracy of the gas sensor in complex environments.

2. Efficient over-current protection

In the circuit system of gas sensor, the phenomenon of over-current is a potential threat, which can generate high heat, easily cause gas sensor failure and even cause serious safety accidents. The NTC chip acts as a “shield” and plays an important role in over-current protection in gas sensor. In the event of an abnormal over-current, the resistance value of the NTC chip increases, limiting the current within a safe range and protecting the components in the gas sensor from damage. The over-current protection function of the NTC chip provides an important guarantee for the safe operation of the combustible gas detector and effectively reduces the safety risk caused by circuit failure.

NTC chip works closely with gas sensor to protect people's lives and property. In order to meet the needs of high-precision gas monitoring, EXSENSE Electronics recommends the use of DT series gold electrode NTC chip. Its accuracy can reach ±0.5%, which can improve the accuracy of the gas sensor monitoring process and meet the needs of more complex and demanding gas monitoring environment. In addition, the small size of the gold electrode NTC chip can meet the development trend of gas sensor miniaturization, making it easier to integrate, and realizing the lightweight progress of combustible gas detector.
