差别的压力流动开关和可调整

Metering substances: water ,air ,oil Please indicate your metering substances with your order. Technical parameters: Storage temperature: -29°C 82°C Ambient temperature: -20°C 71°C Media temperature range: -20°C 93°C Pressure connection: 1/4" SAE(7/16" –20UNF)G , 1/4"NPT etc for optional Max. static pressure: 10/16/20 bar Max. pressure difference: 10/16/20 bar Set point repeatability: ±1% Output mode: WFS11--- one SPDT dry contact output, terminal block wiring WFS14--- two SPDT dry contact output, terminal block wiring Switch: 3A (max) 125/250VAC The series is designed for OEM customers to control flow accurately. It is designed to be a compact,cost-effective differential pressure switch for applications involving hot or cool air ,proof-of-flow,filter monitoring etc. It provides an output when a pre-set difference is exceeded. The set point can be easily modified. The value can set by our professional according to customer’s requirement and print on the label. Differential pressure flow switch with adjustable set point in HVAC system has the same performance with fixed set point switch, they are substitute of target flow switch.
