The United Electric H400-S126B pressure switch is a versatile and reliable solution for monitoring and controlling hydraulic systems. This pressure switch is designed to provide accurate and consistent pressure readings, ensuring optimal performance and preventing potential damage to hydraulic components.
The H400-S126B pressure switch features a robust housing made of brass and stainless steel, providing superior durability and resistance to corrosion. The switch has a maximum working pressure of 3,000 psi (207 bar) and a temperature range of -40 F to 257 F (-40 C to 125 C). These specifications make it suitable for use in various industrial applications, including construction, agriculture, and manufacturing.
The pressure switch operates on a buna-n sealed diaphragm, which isolates the internal components from the system pressure and prevents contamination. The switch has a normally open (NO) contact configuration, which means that it only closes when the pressure reaches the set point. This design ensures that the contact is not closed under normal operating conditions, preventing unwanted activation and potential system malfunctions.
The H400-S126B pressure switch comes with a clear and easy-to-read pressure gauge, which allows users to monitor the system pressure at a glance. The switch also includes an adjustable spring tension, allowing for easy calibration to specific pressure set points. The switch can be set to activate at pressures ranging from 5% to 100% of the maximum working pressure.
The pressure switch is also equipped with a drain plug, which allows for easy drainage of any residual fluid that may accumulate in the switch housing. This feature ensures that the switch remains free of contaminants and maintains its accuracy and reliability over time.
Overall, the United Electric H400-S126B pressure switch is a high-performance and reliable solution for monitoring and controlling hydraulic systems. Its rugged construction, adjustable settings, and easy-to-read gauge make it an essential tool for industrial applications where accurate pressure control is essential.
