The United Electric H122-S156B Pressure Switch is a reliable and versatile component designed for various applications requiring pressure monitoring within the range of 0-100 PSI (Pounds per Square Inch). This pressure switch, with a maximum working pressure of 125 PSI, is manufactured by United Electric, a renowned name in the field of electrical and pressure control devices.
The H122-S156B is a high-quality pressure switch, engineered for durability and precision. It features a robust and corrosion-resistant silicon-bronze diaphragm that ensures optimal performance under harsh environmental conditions. The switch is equipped with a set point adjustment knob, allowing users to customize the pressure threshold to suit their specific requirements.
The switch operates on a simple principle: when the pressure within the system reaches the set point, an electrical contact is made or broken, thereby triggering an action in the connected system. The H122-S156B is a normally open (NO) contact switch, meaning the contact is open under no pressure and closes when the pressure reaches the set point.
The switch is compact in size, making it easy to install in tight spaces. It is designed with a clear liquid-filled gauge, which allows for easy visual monitoring of the pressure within the system. The gauge is also illuminated, ensuring visibility even in low-light conditions.
The H122-S156B Pressure Switch is UL (Underwriters Laboratories) listed, ensuring it meets the highest safety and performance standards. It is also RoHS (Restriction of Hazardous Substances) compliant, making it an environmentally friendly choice.
In conclusion, the United Electric H122-S156B Pressure Switch is a reliable, high-performance, and versatile component, ideal for monitoring and controlling pressure in various industrial and commercial applications. Its robust design, ease of installation, and safety certifications make it a popular choice among engineers and technicians seeking a reliable pressure monitoring solution.
