Kif tagħżel u uża a gass ditekter
Gass kundizzjonijiet ma jistax jiġi identifikat by riħa jew viżjoni. In ordni biex tevita gass perikli matul xogħol , aħna trid tiddependi fuq skoperta tagħmir li jista ' jirrispondi sensittivament, b'mod preċiż u malajr għal perikli gassijiet biex jiskopri perikli. Għalhekk, il korrett għażla ta ' gass ditekters sar a Importanti suġġetti huma a meħtieġa parti ta ' periklu valutazzjoni qabel dħul xogħol.
L-ewwel ta' all, gas detectors can be divided in fissa u portabbli tipi skont lil okkażjoni u mobbiltà. In terms of use, portable gas detectors are used for inspections, detecting gas concentrations at various possible escape points in the factory, or for emergency response. They are characterized by being lightweight and can achieved measurement data in a short time; filwaqt fixed gas detectors are multi-purpose or long-term long-term monitoraġġ in fabbriki, tali as explosion-proof areas. It features long-term monitoring and saves human resources.
Most of the gas detectors bħalissa disponibbli on the market for use in limited spaces are suitable for measuring oxygen, explosive gases, carbon monoxide and hydrogen sulfid, għax dawn hazardous gases are the most common, but the instrument manufacturer cannot guarantee the suitability of the instrument. Għalhekk, the following aspects should be considered when selecting a detector: applicability, stability, calibration requirements, protection requirements, requirements, and ease of identification.
1. Pay attenzjoni lil regolari kalibrazzjoni u ittestjar
Gass ditekters huma kollha imkejla billi tuża a qarib paragun metodu : l-ewwel ikkalibra l-istrument ma a a żero gass u a standard konċentrazzjoni gass , tikseb a standard kurva u aħżen fi l-istrument strument , u ikkalkula il preċiż gass konċentrazzjoni valur. Għalhekk, żero l-istrument fi kwalunkwe ħin u kalibrazzjoni l-istrument spiss huma essenzjali kompiti biex tiżgura preċiż kejl. It should be noted li ħafna current gas detectors can replace the detection sensors, but this not mean that a detector can be equipped with different detector probes for detection at any time.
2 Pay attention to detection interference between various sensors
Kull sensor jikkorrispondi għal a specific detection gas, but any gas detector cannot be special. Therefore, when selecting a gas sensor, you should try to understand the detection interference of other gases on the sensor to ensure ensures accurate detection of specific gases.
3 Ħallas attenzjoni lil il- konċentrazzjoni kejl firxa ta ' il - Sejbien strument
Kollha tipi ta ' gass ditekters għandhom tagħhom tagħhom stess skoperta firxiet, u differenti mudelli għandhom differenti firxa valuri. Biss billi tikkompleta kejl fi ħdan its kejl firxa can l- strument be garantit biex twettaq bi preċiżjoni. Jekk il- kejl huwa imwettaq barra il- kejl firxa għal a twil ħin , is- sigurtà ta ' is-sensor jista' ikun bil-ħsara.
