The Ashcroft B420V Differential Pressure Switch D420V-XFM is a versatile and reliable instrument designed for measuring and controlling the differential pressure in various industrial applications. This switch is part of Ashcroft's renowned B400 series, known for its accuracy, durability, and ease of use.
The B420V switch is a pneumatically operated device that functions by sensing the difference in pressure between two points in a process. It is designed for use with fluids and gases, and can be configured for a wide range of pressure differentials, from 30 mbar to 2 bar (0.45 to 29.5 psi). The switch is available in two pressure ranges: 125/250 VAC, with a maximum current of 15 A.
The switch housing is made of 316L stainless steel, providing excellent resistance to corrosion and ensuring a long service life. The diaphragm is also constructed of 316L stainless steel, and is isolated from the process fluid by a fill fluid, typically glycerin or silicone oil. The switch is sealed with an O-ring and a gasket, making it suitable for use in harsh environments.
The B420V switch is factory-calibrated to ensure precise and reliable operation. It features a clear, easy-to-read red LED indicator that signals the status of the switch, with a blinking light indicating a fault condition. The switch can be easily configured for normally open (NO) or normally closed (NC) operation, depending on the application requirements.
The switch is also equipped with a built-in test button, which allows users to perform a manual test of the switch function. This feature is particularly useful for verifying the switch's operation during installation, commissioning, or maintenance activities.
The Ashcroft B420V Differential Pressure Switch D420V-XFM is designed for use in a wide range of industries, including oil and gas, chemical processing, power generation, and water and wastewater treatment. Its rugged construction, combined with its high accuracy and reliability, makes it an ideal choice for applications where precise measurement and control of differential pressure is essential.
