空中差别的压力控制开关（SA-20CT)

Introduction: SA-20CT series differential pressure switches can sense the pressure difference , vacuum, over pressure, poor flow of the incorrosive gas. Conventional applications include : + Monitoring Filters blocked Alarm Device + Monitoring air blower running status. + Monitoring air of ventilative pipelines + Controlling the largest gas flow of variable gas volume + Monitoring the gas of combustion furnace. Product parameters: Measuring range: 20Pa 200Pa Max.differential pressure: 12000Pa Degree of protection: IP54 Electrical rating value: <2A / 250VAC Working temperature:-15 +60 Storage temperature: -40 85 Min. actuating pressure: standard: 20Pa;min.starting ----------------------------------- interval:10Pa(range: 20 30Pa) Linearity: range 50 500Pa <±3Pa Installation direction: vertical(standard installation style) Hose connection: pipeΦ6.2mm Weight: 100 grams without bracket Repeatability: <±0.025mbarIn the ranges 0.2 to 2mbar Installation: Location: select a location where vibrations are minimal .Ambient temperature should be within the range of -15 / +60.The production calibration of the SA101 is made at room temperature ; mounting locations close to room temperatures are preferred . In systems with high humidity where condensation is possible, thus the entrance should point downwards.
