Differential pressure switches are a particular type of pressure switch that convert a change in the pressure between two systems into an electrical function. The BAPI Differential Pressure Switch is ideal for air filter monitoring, static pressure proving, airflow proving or auxiliary fan actuation. New User? Sold as seen in the photos. KS...A2-7: Klima-Set, Differential pressure switch for air Max. A differential pressure switch is designed to sense a difference in pressure between two pressure sources in the plant for control purposes. The switch can turn on your compressor when tank air pressure levels drop and more air is needed. Kind of pressure: overpressure, relative : Pressure connection: Removed from a working device. The PSW-180 series are compact, differential 5 A SPDT switches with the option of a relay or alarm output. Differential pressure switch for air (DPS) Filter monitor or flow switch for air, non-combustible, non aggressive gases in air conditioning and ventilating installations. Filter monitor or flow switch for air, non-combustible, non aggressive gases in air conditioning and ventilating installations. Incorrectwiring may cause permanent damage to the unit. This means that the lowest pressure that the switch can be set to close at is 40 PSI, and the highest pressure it can be set to open at is 250 PSI. May have some signs of usage\cosmetic wear. Differential pressure switch for air (DPS) Filter monitor or flow switch for air, non-combustible, non aggressive gases in air conditioning and ventilating installations. From $62.90 In. Setting the cut-out pressure is basically the same as setting the cut-in pressure. Our product range contains:Thermostats, Motorized Zone Valves, Ball Valves, Valve Actuators, Damper Actuators, Controllers, Radiator valves, and etc. Caution:+ The Pressure Switch should be mounted vertically which can prevent affecting on precision from inner atmosphere film weight.+ To prevent electrical shock or damage to equipment , when the cover is removed ,ensure the power supply is switched off.+ Complete wiring and check the connections before applying power . Use them to automate controls or activate an alarm in your process. EPD1S Series Differential pressure, compact, economical, stripped, can be used for high/low limit control, Working Ranges from .22 - … systems with high humidity where condensation is possible, thus the entrance should point downwards. 40 COPYRIGHT © Hotowell International Co., Limited ALL RIGHTS RESERVED.
