Features:Brand: ELECALLProduct Name: Differential Pressure SwitchModel: EPDSMax. Working Pressure: 10KPaType: Gas SensorOutput: Analog SensorMounted Screew Diameter:4mmPackage Size:110*108*110mmColour:As Picture ShownProduct Material:--Switch Material: PA6.6--Shell Material: Plastic--Diaphragm Material: SiliconeTemperature Range: Medium and ambient temperatures from -20 ~ 85 CMedia: air, non-flammable and non-corrosive gases Introduction:This pressure switch is primarily used in ventilation and air conditioning systems for monitoring the air flow in air ducts, as well as in filters, flaps and fans. They are suitable for air and also other non-inflammable and non-aggressive gases. Application:This switch is capable to sense tiny pressure change and widely used to control the flue of aerator, to monitor and fan and air conditioner. It is also suitable for over heating protection and frost protection in industrial cooling system. Due to its outstanding design, the setpoint can be adjust visually.
