The gas detector sensor is an instrument tool specially used to detect the concentration of gas leakage. It is usually used to detect the composition and concentration of the gas. With the increasingly mature development and gradual improvement of sensor technology, gas detectors have become a popular and practical tool for the whole people. And when we select the gas detector sensor, what are the parameters that we need to know? Next, JRPanel will take you to find out!

The Main Parameters of the Gas Detector

When selecting the gas detector sensor, we must incorporate some selection factors into our selection criteria, and we must also consider our own practical places. The following are several common gas detector parameters:

1. Indication error: Under test conditions, the difference between the indicated value of the detector and the concentration value of the standard gas used.

2. Detection range: The concentration range of the gas to be measured that the detector can accurately measure under normal working conditions.

3. Alarm error: Under test conditions, the difference between the alarm indication value of the detector and the alarm setting value.

4. Response time: Under test conditions, the time from when the detector is exposed to the gas being tested to when it reaches 90% of the stable indication value.

How to use the gas detector sensor ?

As an instrument with high precision requirements, when we use the gas detector sensor, we must strictly abide by the relevant usage methods, so that the gas detection work can be more accurate and guaranteed. The gas detector is a highly precise instrument. If you want to ensure its precision, you need to use it in accordance with the prescribed method. The following is an introduction to the use of the gas detector sensor:

1. Timely calibration and testing. No matter what the instrument is, it should be carefully checked and calibrated before use, especially for toxic gas detectors. If you do not perform timely calibration and testing before use, the accuracy of the instrument itself may deviate. In this case, if firefighters enter the place where the toxic gas is leaking, it may cause serious casualties, and the consequences will be disastrous. Therefore, it is very necessary to perform timely calibration and detection before the gas detector is used.

2. Pay attention to the concentration measurement range of the detection instrument. The gas detector has its fixed detection range. Only when the measurement is completed within its measurement range can the instrument accurately perform the measurement. However, measuring beyond the measuring range for a long time may cause damage to the sensor. For example, a toxic gas detector may cause damage to the sensor if it works for a long time in a higher concentration of toxic gas environment.

3. Pay attention to the use environment of the testing equipment. Toxic gas detectors should pay attention to preventing electromagnetic interference during use. Errors may occur if electromagnetic interference occurs during use. In addition, the on-site temperature, humidity, pressure, wind speed, wind direction, whether there is dust, whether it is corrosive, whether there is other gas interference, etc. will also affect the detection effect of the toxic gas detector.

4. Pay attention to the maintenance of the detector. Do not place or hang objects on the gas detector. The installed gas detector cannot move the position of the device at will. Try to choose products with replaceable probes when purchasing, so as to facilitate maintenance and replacement in the future.

The above is the introduction of the sensor parameters of the gas detector. I hope this article can provide you with a reference when selecting models. Whether it is the selection of the gas detector sensor or its use, we all know the relevant parameters of the gas detector sensor, so that we can truly have a full understanding of the characteristics and functions of a product.
