The ASCO PB11B Tripoint Pressure Switch is a versatile and reliable solution for various pressure monitoring applications in industrial and commercial settings. This pressure switch, designed for use with 125/250VAC power supplies, features a tripoint operating characteristic that offers superior accuracy and flexibility.
The ASCO PB11B Tripoint Pressure Switch is engineered to withstand demanding environments, boasting a rugged, compact design with an operating temperature range between -40 F and 257 F. It is constructed with high-quality materials that ensure durability and long-lasting performance, including a stainless steel diaphragm and an armored set screw, which provides added protection against external forces.
This tripoint pressure switch operates on a three-point calibration, allowing it to be set at three different pressure points: a low pressure (LP), a medium pressure (MP), and a high pressure (HP). This unique feature makes it suitable for applications where precise pressure control is essential, as it provides an additional level of protection against over- or under-pressure conditions.
The ASCO PB11B Tripoint Pressure Switch is easy to install and maintain, featuring a simple wiring configuration and a clear pressure scale on the front panel for easy reference. The switch comes with a 1/4 NPT inlet and outlet connection, accommodating various industrial fluid types. In addition, it is available in a range of voltage options, including 115VAC, 120VAC, 230VAC, and 240VAC, to meet diverse power requirements.
When the pressure inside the application reaches the preset LP, MP, or HP, the switch will activate and output a signal, providing an indication of the pressure condition. The ASCO PB11B Tripoint Pressure Switch is compatible with various signaling options, such as normally open (NO) or normally closed (NC) contacts, as well as an optional solenoid valve.
In summary, the ASCO PB11B Tripoint Pressure Switch is a robust, versatile, and accurate pressure monitoring solution, ideal for various applications in industrial and commercial settings that demand precise pressure control and reliable performance. Its rugged design, easy installation, and flexible calibration make it an invaluable addition to any pressure monitoring system.
