( Brand: Murphy ), ( Manufacturer Part Number: A20DPE-50-SR40 ), ( Part Type: Pressure Switch )
The A20PDE-50-SR40 and A20DPE-50-SR40 are two pressure switches manufactured by Murphy Gauge, a reputable name in the field of pressure and flow measurement devices. These switches are designed to meet the demands of various industrial applications that require accurate and reliable pressure sensing.
The A20PDE-50-SR40 is a 0-50 psi pressure switch, specifically designed for applications where the operating pressure does not exceed 50 pounds per square inch. It features a set point of 0, which means it operates at atmospheric pressure when not activated. The switch is equipped with a 20 ampere contact that closes at the set point and opens above it, making it suitable for applications requiring an electrical signal when the pressure reaches the desired level.
The A20DPE-50-SR40, on the other hand, is an identical switch with a different contact rating. It also operates at a pressure range of 0-50 psi, but its contact rating is 20 amperes deenergized, meaning it opens at the set point and closes above it. This configuration is suitable for applications where the power source needs to be switched off when the pressure reaches the set point.
Both switches are built with high-quality materials to ensure durability and reliability in harsh industrial environments. They feature a stainless steel diaphragm and a buna-n rubber seal, providing resistance to corrosion and ensuring a long service life. The switches also come with a powder-coated steel housing, ensuring protection against external damages and providing a sleek, professional look to your equipment.
In conclusion, the A20PDE-50-SR40 and A20DPE-50-SR40 are reliable and versatile pressure switches that can be used in a variety of industrial applications. Their high-quality construction, along with their adjustable set points and contact ratings, make them an excellent choice for any application requiring accurate pressure sensing and control.
