Okvare od plin detektorji in kako to reševanje njih
What are the common faults of gas detectors? How to solve common faults of gas detectors?
The naslednje pogosti napake:
1. Tam je ne izmerjen plin v zrak, but vrednost spremembe veliko ali skoki;
2. nizka koncentracija plin ne more biti zaznana;
3. Kdaj vrednost is 0} or the alarm vrednost is not doseženi v zrak, it volja tudi alarm;
4. Nepravilno pregled.
How to solve common faults of gas detectors:
1. The range of short-term zero point variation less than 1% of the maximum range is considered normal, while the long-term drift less than 2% of the maximum range when gas is not measured is considered normal. If it exceeds this range, it is necessary to confirm whether there is measured gas on site. The temperature and humidity in the air fluctuate greatly and the numerical value is unstable.
2. Confirm whether the gas detector has undergone zero calibration or target point calibration. If there is a detected gas, the zero calibration operation may not be able to detect low concentration gas. If there is a detected gas, target point calibration will be performed. However, if the calibrated concentration value is inconsistent with the actual concentration value, the value of the gas detector will change greatly or the detected value will decrease.
3. If the problem ne more biti rešen, it is potrebno za potrditi zapotrditi za plin detektor je vplival plin senzor sko preskozi visoka koncentracija plin ali visoka koncentracija plin plin. Če plin senzor is je prizadeto in starano za 24 ure, if the vrednost is nestabilno, plin senzor LAHKO UDARJE in poškodovan, zahteva Zamenjava.
Nizka koncentracija plin plin ne more biti zaznan
1. Preveri če plin črpalka od plin detektor is deluje deluje pravilno. Uporaba tvoji prsti do za blok zrak dovod za 5 sekunde. If tam is opazno privlačnost, if THERE IS No attraction, check if the Air Inlet je blokiran.
2. Umeritev The Nič Točka Z dušik Or IN CLEAN Air, and Check AFTER kalibracija.
3. After calibrating the zero point, if the measured gas cannot be detected, the factory settings of the gas detector need to be restored.
4. The zgoraj koraki imajo been dokončani, but not be zaznani. It It IS POTREBNO POTRDITEV JE JE KATERI PLIN BITJE IZMERJENO ON SITE, Or if the koncentracija plin bitje izmerjeno is resnično zel nizko, in it ne more biti zaznano spodaj najmanj zaznavanje natančnost OF GAS senzor.
Alarm kdaj vrednost is 0} ali the alarm vrednost is not doseženi v zračni promet
1. Preverite za: različni alarm parametri of plin detektor ime been spremenjeni;
2. Check if the alarm mode and alarm of the gas detector have been modified;
3. Preverite za: alarm stanje of plin detektor is a koncentracija alarm ali drugo napaka alarm. The koncentracija alarm zasloni the besede A1 ali A2, in the rdeča lučka utripa;
4. If the gas detector alarm is caused by human operation modification, it can be resolved by rešen z restavriranje the tovarna namestitev. The fault alarm needs to be naprej preverjeno za short circuits, open circuits, poor contact, sensor faults, etc., or returned to to for pregled.
1. Confirm whether the on-site gas concentration is correct, and there is a significant difference between the theoretical value and the actual value. Use a standard gas calibration gas detector to ensure the accuracy of the detection, or send it to a third-party measuring institution for calibration.
2. Če plin plin senzor is uporabljeno za a dolg čas, meritev vrednost lahko ima napake. It je potrebno do prvo potrditev z proizvajalec ali plin zaznavanje instrument can nadaljevanje be uporabljeno. If the senzor same is close to its storitev life, it can ti ti be normalno so pobitje ponovno kalibrirano za a kratko obdobje časa, ven meritev vrednost OD PLIN detektor LAHKO IZKUŠNJA drift detection errors. It is priporočeno do zamenjava the gas sensor.
