1. Ambient temperature and humidity The temperature is too low and the sensor is exposed to dirty environments with dust particles or oily vapors that will degrade the life of the sensor. It should be ensured that the sensor sampling film is not blocked by ice, mud, or dust.
High or low humidity can affect the normal operation of electrochemical sensors. When the relative humidity is lower than 25%, after a few days of operation of the sensor, the internal sensor electrode solution will be slowly dried by the dry air and will lose its effect; when the ambient humidity is higher than 90%, the humid air may be The electrodes inside the sensor can enter and the sensor may lose sensitivity.
2 The sensor itself requires a shell around the sensor. During use, the inlet of the catheter must be sealed completely and the cover of the transmitter housing must be tightly tightened to prevent moisture or rain from entering the transmitter circuit, causing the instrument to malfunction.
3 sensor peripheral protection sensor should be kept in a good position for ventilation, in order to prevent long-term leakage of gas accumulation, consumption of electrolyte, reduce the life of the instrument; In order to prevent rainwater into the sensor, the top is best to install a rain cover in the daily During work, check the instrument for water intake and ensure normal operation.
4 Prevention of gas leakage In order to reduce the risk of gas leakage as much as possible, create a ventilation environment at the possible source of leakage, configure an alarm exhaust device, and prevent insulation from generating sparks. The gas alarm detector is equipped with a sound and light alarm function so that it can be timely Remind that there is enough preventative time.
5 users to strengthen the self-checking force For the instrument with a test button, press once every certain time to determine whether the instrument alarm is normal; in use, the user should be equipped with the appropriate standard gas, regular comparison of the instrument, if the measurement is found If the deviation is large, the user should promptly contact the gas alarm maintenance personnel to calibrate the maintenance and verify it.
At present, there are many kinds and types of gas alarms on the market, but the detection principle is almost the same. During the use and maintenance of gas alarms, routine maintenance should be done. The normal service life of gas detectors is 2 to 3 years. Some suggestions for writing a life span of 5-6 years refer to the related internal component parameters and then make judgments. In a well-maintained situation, the service life can be extended, and the corresponding work is mainly done in several ways:
