Under the high pressure of environmental protection, gas detector helps pharmaceutical enterprises t

It is understood that pharmaceutical companies in the production of drugs in the process of common processes for synthetic reaction, fermentation, etc., these links will produce a lot of waste gas and water, causing pollution. For example, pharmaceutical companies produce vocs-containing waste gas in the process of synthesis reaction, which will affect the air quality of the production environment and the surrounding environment if it is not processed by special process. Therefore, it is necessary to take targeted treatment methods and necessary detection of air quality in the pharmaceutical production environment.







According to the industry, different enterprises need to find suitable waste gas treatment methods to eliminate the pollution of harmful gases. In addition, the selection of appropriate gas detector is conducive to better prevention of exhaust pollution.







Gas detector is a kind of instrument used to detect the concentration of leaked gas. With the continuous increase of environmental pressure and the continuous development of the pharmaceutical industry, pharmaceutical companies have been improving the demand and requirements for gas detector, and some automation and intelligent technologies have been applied to the innovative research and development of detector.







Recently, some pharmaceutical companies have demanded more accurate readings of gas detectors, longer mission life of equipment, and reduced replacement frequency and cost. To this, gas detector manufacturer says, the service life of gas detector depends on its core component -- sensor. Once the sensors fail, that means the gas detector is dead.







Currently, there are a variety of sensors on the market, and one sensor does not have the ability to detect all gases. According to the difference between gas and environment, it can be roughly divided into sensors used to detect the concentration of toxic gas and sensors used to detect the explosive concentration of combustible gas.







Among them, the sensor used to measure the concentration of toxic gas is mostly electrochemical sensor, it is based on the principle of electrochemical work of the sensor, the main impact on its life is the electrolyte, the general sensor in 2 ~ 3 years, the electrolyte can no longer work properly.







Most sensors used to detect the concentration of combustible gas are catalytic combustion sensors, and their service life is about 3 ~ 5 years.







Therefore, users in the choice of gas detector, the sensor performance of the equipment, the life of the necessary understanding, which also requires the gas detector manufacturers in the procurement of sensors, should choose the regular manufacturers of sensors, in order to maintain a long life of the equipment.







In addition, in the gas detector reading, a technician said that in general, the gas detector reading is mainly affected by environmental factors. These include changes in pressure, humidity and temperature.







On the pressure side, if the pressure changes dramatically (such as through the air plug), the sensor reading of the gas detector may present temporary fluctuations, which may cause the detector to give an alarm.







In terms of humidity, if there is a significant change in humidity (such as from an air-conditioned dry environment into a humid outdoor environment), the vapor in the air will drive away oxygen, causing the oxygen reading to drop a little.







In terms of temperature, if the temperature fluctuates violently, the sensor reading of the gas detector may drift. In this case, the technician recommends that the operator calibrate the instrument at the work site to minimize the impact of temperature changes on the reading.
