Practical application of methane sensor

Practical application of combustible gas sensor

Methane sensors can be divided into semiconductor type, catalytic combustion type and infrared type according to different principles. Catalytic methane sensors are generally used for gas leakage alarms in public places such as restaurants. This type of sensor has high sensitivity and fast response speed, and can accurately and timely detect and issue early warning signals. MEMS methane sensors are suitable for detecting gas leaks in consumer electronics such as mobile phones and computers; they are also suitable for use in home and commercial use in combustible gas leak monitoring equipment, gas leak detectors, and fire/security detection systems. Industrial infrared methane sensor is suitable for industrial field instrumentation, safety protection monitoring.

Methane Sensors Guide

We have summarized the following questions to help you make better choices.

Question

Why do methane sensors (semiconductor type) age?


Answer

This is determined by the characteristics of the semiconductor sensor. When it is put on hold (not energized, at room temperature), water vapor and impurities will adhere to the surface and affect the performance of the sensor. Aging is actually heating at high temperature with electricity to clean the impurities attached to the surface of the sensor, so that the gas-solid interface of the sensor can reach the best state and maintain the activity and stability of the sensor.

Question

Why does the methane sensor (semiconductor type) have zero point and sensitivity drift during use?


Answer

There are five reasons for zero and sensitivity drift:

1) The aging time before calibration is short, and the aging time is not carried out according to the time specified in the gas sensor instruction manual;

2) The ambient atmosphere of the gas sensor used is complex, which affects the zero point and sensitivity;

3) The temperature and humidity conditions in the application environment of the gas sensor fluctuate greatly, resulting in a large drift of the sensor zero point and sensitivity (for example, calibration under standard working conditions and working under extreme conditions);

4) The gas sensor is not connected to the circuit according to the conditions specified in the manual;

5) The gas sensor is subject to severe vibration or destructive external conditions.

Question

The methane sensor (semiconductor type) has been used in the kitchen for a long time. The sensor is polluted by oil fume, and the surface is covered with oil stains. What is the impact on the gas sensor?


Answer

If the soot covers the sensor so that the gas cannot enter the reaction interface, the sensitivity will be affected, and the test may not be possible in severe cases. We recommend that you do a good job of protecting the gas sensor when redesigning the alarm, and choose the best installation location for the alarm.

Question

What is the most suitable concentration for methane sensor (semiconductor type) calibration?


Answer

Flammable gases are generally selected at one-tenth and one-fifth of their lower explosion limit as calibration points. CH4 4000-5000PPM, C3H8 1000-2000ppm, H2 400-800ppm, you can determine the best calibration concentration and calibration method according to your actual needs and experience.

Question

How do methane sensors (catalytic combustion type) distinguish between measuring elements and compensation elements?


Answer

1. Mark D or the big hole is the measuring element, mark C or the small hole is the compensation element;

2. The sealing part is the measuring element, and the other side is the compensation element.

Question

There are so many types of methane sensors, how should I choose?


Answer

Semiconductor methane sensor: high sensitivity, long life, low cost, simple drive circuit, used in household gas leak alarms, industrial combustible gas alarms, portable gas detectors

 

Catalytic methane sensor: good anti-interference performance, fast response speed, stable and reliable operation of components, linear output voltage of anti-hydrogen sulfide and organic silicon bridge, good repeatability and selectivity, used in flammable gas leak alarms, combustible gas detectors, gas concentration meters

 

Industrial infrared methane sensor: high resolution, anti-water vapor interference, non-toxic, providing UART, analog voltage and other output methods, temperature compensation, used in industrial field instrumentation, industrial process, safety protection monitoring.

 

MEMS combustible gas sensor/module: MEMS technology, the product has good vibration resistance, low power consumption, can be powered by battery, patch welding, used in consumer gas leakage electronic products, combustible gas leakage monitoring devices, gas leak detectors, fire protection /security detection system.
