How to avoid electromagnetic interference when using combustible gas detectors?
The combustible gas detector is an instrument used to detect the concentration of combustible gases. It can be divided into two types: catalytic type and infrared optical type. So how to avoid electromagnetic influence when using combustible gas detector?
Here are some ways to avoid electromagnetic interference:
*Choose an instrument with strong anti-interference ability: Choosing a combustible gas detector with high anti-interference ability can effectively reduce the impact of electromagnetic interference.
*Stay away from sources of electromagnetic interference: Try to keep the combustible gas detector away from sources of electromagnetic interference, such as motors, transformers, radio transmitters, etc.
*Avoid use in strong magnetic field environments: Avoid using flammable gas detectors in strong magnetic field environments, such as magnets, electromagnets, etc.
*Use shielded wires: Using shielded wires can effectively reduce the impact of electromagnetic interference. Connect the power cord and signal wire of the combustible gas detector to the shielded wires.
*Adjust the detection position: If the detection position of the combustible gas detector is affected by electromagnetic interference, the detection position can be adjusted to reduce the impact of electromagnetic interference.
*Regular maintenance and calibration: Regular maintenance and calibration of combustible gas detectors can ensure the accuracy of its detection results, and can also detect and solve electromagnetic interference problems.
What are the transmission methods of gas detectors?
1. 4-20MA: called three-wire system, analog output;
2. RS485: called four-wire system, digital output;
3. Switching value: 110V passive output;
4. Relay.
What types of remote transmission are there?
1. 4G: As the name suggests, 4G is a data upload cloud platform, and the cloud platform has links to users;
2. LORA: There is a sending end and a receiving end, and the receiving end is installed on the host or computer;
3. Wifi: This means that there must be Wifi coverage.
