Gas detektor er et instrument værktøj til detektion gas lækage koncentration, som hovedsageligt bruger sensorer til detekterer typerne af gasser nuværende i miljøet. Gas sensorer bruges til detekterer sammensætningen og indholdet af gasser. Mange miljø faktorer kan påvirke aflæsningerne af gas detektor sensorer under brug, inklusive ændringer i tryk, fugtighed, og temperatur. Så hvad specifik faktorer påvirker aflæsning af gas detektorer% 3f
1. Tryk ændringer
Hvis trykket ændres markant (sådan som hvornår passerer gennem gas stikket)% 2c den gas detektor sensor læsning maj oplevelse midlertidig udsving% 2c som kan forårsage detektoren til lyd en alarm. Når ilt volumen procent forbliver stabil ved omkring 20.8 procent og den samlede tryk falder betydeligt , ilt brugt til vejrtrækning i miljøet kan blive en fare.
2. Humidity change
If there is a significant change in humidity (such as when entering an outdoor humid air environment from a dry environment with air conditioning), the water vapor in the air will drive away oxygen, causing the oxygen reading to drop by up to 0.5 percent . The gas detector sensor is equipped with a specialized filter to eliminate the impact of humidity changes on gas readings. This effect will not be immediately detected, but it will gradually affect the degree of oxygen after several hours.
3. Temperatur ændringer
When cleaning a gas detector, it is necessary to frequently clean the outer surface of the instrument with a damp cloth, and the use of cleaning agents is strictly prohibited. Because the cleaning agent may also contain silicon, it can damage the gas detector sensor. When storing, choose a safe and dry place as much as possible, with a storage temperature range of 18 degree -30 degree . Before using a stored gas detector, it is necessary to reproduce the calibration of the detector. During transportation, gas detectors should be protected with appropriately padded transportation packaging to prevent accidental damage to the instruments during transportation.
