Relevant overview
It is often used to sense the pressure difference, vacuum, overpressure and airflow difference of non-corrosive gases in the pipeline, such as the following working conditions:
· Monitoring filter blocking alarm device
· Fan operating condition monitoring
· Gas monitoring in ventilation ducts
· Control the maximum airflow in a variable gas volume system
· Gas control in the furnace

Scope of application
Series gas differential pressure switch is used to detect gas pressure and pressure difference, such as detecting filter blocking alarm device, detecting the start/stop status of fan in air conditioning unit, gas monitoring in ventilation pipe, etc.
