Some switches have differentials as low as 5 PSI. Pressure switch settings, common to many air compressors, are set for a range of 40 to 250 PSI and an adjustable differential of 35 to 60 PSI. Designed to be the most adaptable switch on the market, the 69J Series offers the user the flexibility to build the pressure switch around the compressor – not the other way around. Differential pressure switches tend to be used for energy saving or preventative maintenance, for example; monitoring air filters for blockages. The switch is actuated by a difference in pressure between the two sensing elements. It may be used to sense positive, negative, or differential air pressure… P12 Series differential pressure controls can be used with oil and non-corrosive refrigerants. Particulate (Dust or Broken Bag) Transmitters, Position Indicators / Switches / Transmitters, Chemical Resistance Guide for Elastomers III, T: +1 800.872.9141 +1 219.879.8000 F: +1 219.872.9057. General Air Products’ pressure switches (also used for vacuum and called a vacuum switch) consist of a switch mechanism that is connected to a bellows or diaphragm that reacts to system pressure. HVAC Differential Pressure Switch which applies to controlling air and fire-protection dampers and monitoring air filters and ventilators. The air compressor pressure switch will also help your machinery maintain the proper pressure level as you go about your work. If your pressure switch needs fall outside of the products shown here contact us for details on our complete pressure switch line. When the differential pressure exceeds your setpoint, the switch is activated. Filter monitor or flow switch for air, non-combustible, non aggressive gases in air conditioning and ventilating installations. Differential pressure switch for air (DPS) dps-ge51colres.jpg. Air Differential Pressure Switch Adjustable Micro- Pressure Air Switch T3J6 This pressure switch is mainly used in ventilation and air conditioning systems to control the air flow in the air ducts, as well as in filters, ailerons and fans. Rely on Honeywell pressure switches to perform in critical applications that experience performance spikes and other extreme conditions. Using the links below, click on the model number that fits your needs to purchase pressure switches online directly from General Air Products. A Differential pressure switch is a device which utilizes a differential air pressure to actuate an electric switch at a pre-set actuation point. Pressure Switches Ashcroft®pressure switches are provided in a variety of configurations to meet most installation requirements in nearly every industry. You must have JavaScript enabled in your browser to utilize the functionality of this website. There are various optional pressure ranges, and 2 … Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners, duct heaters, humidifiers, exhaust fans and duct booster fans. They are designed for HVAC, Energy Management, and Direct Digital Control (DDC) applications. This style is available with an unloader valve option to prevent the compressor from starting under load. A long list of choices include differential pressure switches, explosion-proof pressure switches, NEMA 4 and NEMA 7 rated pressure switches as well as electronic pressure switches. As pressure increases, available differential increases as well. Pressure switches are ideal for ensuring pressure levels remain within ranges best suited for safety and production. It may be used to … Conventional applications include : + Monitoring Filters blocked Alarm Device + Monitoring air blower running status.
