The Importance of Maintaining Combustible Gas Detectors
Due to the harsh working environment of combustible gas detectors, they generally need to be installed outdoors, where they are often exposed to wind, sun, and various polluted gases. These gases can also enter the detector, and this is unavoidable. We can consider this situation as an objective way of damage. These damages will have a certain impact on our data. In order to better realize its value, special attention needs to be paid to maintenance and upkeep, minimizing the possibility of obstruction of the combustible gas detector and ensuring the correct value of the detected data. Therefore, cleaning and maintenance of the combustible gas detector is very important and an important measure for protective work.
Of course, if the combustible gas detector is not regularly maintained, it will also increase its aging rate, and for enterprises, the loss cost of industrial components is also significant. Enterprises must remember not to forget to replace equipment after a period of time to avoid causing losses to the company.
Detailed Introduction to Calibration Methods for Gas Detectors
The method of pre mixing calibration gas is the * * and * * * method of gas sensor calibration. Pre mixed calibration gases can be compressed and stored in gas cylinders at a certain pressure. The size of these bottles can be arbitrary, but during on-site calibration, people prefer small and lightweight gas cylinders. These small and portable gas cylinders can be divided into two categories: low-pressure and high-pressure gas equipment.
Low pressure gas cylinders with thin walls and light weight are usually non recyclable and disposable. High pressure gas cylinders are designed for pure hazardous chemicals. For calibration gases, these gas cylinders typically have thick walls and can withstand a pressure of 2000psi.
In order to calibrate the sensor and allow high-pressure gas to flow out of the high-pressure cylinder, a pressure regulator is required. It consists of a pressure controller, a pressure gauge, and a flow restriction hole. A flow restriction hole is a very small linear hole that allows a certain amount of air flow under a given pressure.
