Selection and Application of Air Flow Switch

Air flow switch is also known as gas flow switch and air flow sensor. It is generally used to monitor the flow rate of air pipe or ventilation pipe. When the air flow rate is too small or too large, the switch signal is output to cut off the host or connect the circuit to perform relevant operations. Generally speaking, this is the upper limit or lower limit alarm function.

According to the different application places, the flow switches selected are also different. Now, we will recommend different type air flow switches according to different fluid conditions or workplace

1. Explosion proof Air Flow Switches.
Explosion proof place, i.e. flammable and explosive place, where there are flammable gas, vapor, dust or fiber that may cause fire or explosion hazard. In such a place, explosion-proof performance is required for the equipment to be installed, that is to say, explosion-proof flow switch is required. At present, the GE-374-EX and GE-325 explosion-proof flow switches can meet this requirement

2. High Temperature air

If it is suitable for high temperature air flow switch, most of them require metal flow switch. At the same time, the electrical components should be isolated from the fluid remotely. At present, GE-374-EX series explosion-proof and high temperature resistant air flow switch can meet this requirement

3. High Pressure Pipeline

Because the pipeline pressure is very high, the sensor parts need to have high pressure bearing capacity. If there is no requirement for explosion-proof and high temperature, GE-327 series flow switch will be a very affordable choice

4. Corrosive gas Flow switch

If the air in the pipeline is mixed with corrosive gas, the corrosion-resistant probe must be selected. In this case, we need to recommend appropriate products according to the speed of the fluid. Generally, GE-313 or GE-328-PTFE series flow switches can be used for Corrosive Gas
