How far can a body detector detect jurisdiction?
How far can your gas detector detect jurisdiction?
Answer: Often, users may ask this question and mistakenly believe that gas detectors can detect long distances. However, there is a misunderstanding here. Gas detectors, especially fixed gas detectors, are generally diffuse, meaning that gas needs to diffuse to the sensor head of gas detection in order for them to detect concentration. Otherwise, even if the toxic gas is nearby, it cannot be detected. For example, the human sense of smell is a very sensitive organ that can detect trace gases in the air up to the ppb level. Sometimes we need to be very close to ask, and sometimes we can smell them far away. This is due to the direction of air flow and concentration ratio. Gas dissolved in atmospheric air may not be detected by nearby gas detection equipment due to wind direction flow. As the gas flows further away from the gas leakage point, the gas concentration also decreases. Therefore, detecting gas concentration in a distance is safe, but it does not mean that all positions are safe, and the concentration is so low. There is no strict standard for installing one from a nearby location. Only by considering the on-site situation and the distribution of hazard sources, can the layout be reasonable. It is recommended to install one device within a range of 20m2 or 10-20 meters.
What are the environmental conditions for installing a gas detector?
Answer: Gas detectors have their own working conditions to adapt to, and the main needs to pay attention to basic conditions such as humidity, temperature, and pressure. Generally, it is suitable to install them in our environmental factory buildings, and they can be directly fixed. However, when we install them in enclosed spaces, such as pipelines and flues, in these special environments, we need to pay attention to understanding the working conditions. The vast majority of our gas detectors, No matter what brand, the conditions they can adapt to are room temperature- 20 to 50 degrees Celsius, humidity below 90% without condensation, pressure within the range of 100kp. If the environmental conditions are not included, it will affect the accuracy of measurement and the service life of the instrument. At this point, we need to consider adding gas pretreatment equipment. To perform gas processing and allow gas that meets the conditions to enter the gas sensor head.
Is there any impact of excessive dust in the installation location?
Answer: Excessive dust in the gas can easily cause adsorption on the gas sensing components of the gas sensor, leading to blockage and a decrease in detection accuracy. Therefore, when using in a high dust environment, it is necessary to filter the dust and regularly clean the dust according to the situation. Remember not to wash with water or wipe with alcohol or other solutions. Only clean and soft cloth can be used to clean the surface of the sensor.
