The Ashcroft B426S Pressure Switch is a pneumatic pressure switch designed for use in various industrial applications. This switch is rated for a working pressure of 30 psi (pounds per square inch) and is suitable for applications where precise pressure control is required.
The B426S is a compact and rugged switch, constructed from high-quality materials to ensure durability and reliability in harsh environments. Its housing is made of brass, providing resistance to corrosion and ensuring a long service life. The switch comes with a stainless steel diaphragm, which is also resistant to corrosion and can withstand the rigors of industrial use.
This switch operates on a pneumatic principle, using compressed air to actuate the switch mechanism. When the working pressure in the system reaches the set point, the diaphragm is pushed in, which in turn closes the switch contact. This contact can be configured to make or break a circuit, depending on the application requirements.
The Ashcroft B426S Pressure Switch is easy to install and maintain. It comes with a threaded connection for easy attachment to the system piping. The switch also features a transparent cover, which allows for visual indication of the switch status. The switch status can be indicated using various options, such as a red or green LED light or a pilot light.
This switch is suitable for use in a wide range of industries, including oil and gas, chemical processing, and power generation. Its compact size and rugged construction make it an ideal choice for applications where space is limited and the environment is harsh.
The Ashcroft B426S Pressure Switch is a reliable and accurate pressure control solution that can help ensure the safe and efficient operation of industrial systems. Its high-quality construction, easy installation, and versatile configuration options make it a popular choice for industrial applications where precise pressure control is essential.
