In order to ensure as flexible operation as possible, the differential pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A … Differential pressure controls can be used to reduce available differential pressure in a specific area of a network (area control), before each building subscriber station or at each control valve. The Gages and Switches are ideal for pressure, velocity, flow applications and single pressure. ... (J-Size) Sealed Basic Switches Basic Switches (Z-Size) ... (Velocity Type) MEMS Flow Sensors (Differential Pressure type) Pressure Sensors They have NEMA-4X housings to withstand harsh environments. These switches can activate when pressure is added, or when pressure is removed, and turn the circuit on or off when a certain level of pressure has been attained. SOR differential pressure switches are suited for a wide range of applications from filter maintenance to high static pressure flow … Differential Pressure Switches. Pneumatic flow switches are also useful in applications where there’s a necessary pressure differential between different areas of ducting. We offer an extensive product line, including miniature pressure switches, differential pressure switches, solid state pressure switches and flow switches. The BARTON measurement technology portfolio includes differential pressure (DP) indicating switches that are available in a wide variety of safe working pressures and differential pressure ranges. Industrial Differential Pressure Switch or Alarm PSW-180. Call us today for more information! Range – The span of differential pressures or flow rates within which the sensing element of a given switch can be set to actuate an electric switch.. Set or Actuation Point – The exact air pressure or flow rate which will cause the electric switch to actuate.. Low Differential Pressure Sensor PSE550 ・Suitable for applications such as air current volume maintenance, filter blockage, and liquid surface detection ・Analog output (voltage/current) Data Download CAD Manual DoC PDF The PSW-180 series are compact, differential 5 A SPDT switches with the option of a relay or alarm output. + Monitoring air of ventilat ive pipelin es + Controlling the largest gas flow of variable gas volume + Monitoring the gas of combustion furnace. Across the hundreds of varieties of pressure switches, three things remain constant: a sensor (either bellows or diaphragm), a spring for determining the range set point and a snap-acting micro-switch. Pressure Switches are available in two basic categories: Fixed Differential Pressure Switches and Adjustable Differential Pressure Switches. Mid-West Instrument, located in Sterling Heights, MI is one of the leading designers and manufacturers of differential pressure gauges and switches in the U.S. We serve a range of industries and markets with quality pressure switch products. The pressure switches are fitted with a manual switch that will lock the contact system in the open position independently of the pressure in the system. Differential switches are used to sense pressure differences between two points in a system, and actuate if a pre-defined difference is met. Please correct me if I am going about this the wrong way, but my plan would be to pipe the positive port on the DP switch into the duct at the blower outlet and to pipe the negative port on the DP switch into the duct at the blower inlet. Typical flow rate applications measure gases, vapours and aggressive or viscous liquids in pipelines as well as bulk solids on conveyor belts. 50 years experience in partnering with customers by engineering solutions and delivering value. The PSW845 is a rugged differential pressure switch, with excellent bypass characteristics. Flow rate measuring instruments measure the amount of substance that flows through a pipe cross-section per time unit. Differential pressure switch, air flow, SPDT, 5 amps non-inductive 277 Vac, 0.25 to 1" WC The model A2G-40 differential pressure switch, in the Δp function, monitors filters and ventilators in ventilation ducts and air shutters. DIFFERENTIAL PRESSURE TEMPERATURE FLOW ... We offer wide range of products for measurement and control of temperature, pressure, level and flow. Switching contacts are rates to 3 amps @ 250vAC, allowing the switch to be used for alarming, or to operate fan motors to maintain pressure or flow ranges. Mid-West Instrument, located in Sterling Heights, MI is one of the leading designers and manufacturers of differential pressure gauges and switches in the U.S. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.
