SAPPBU90 is a multi-purpose, adjustable pressure switch that is commonly used across a variety of applications. The SAPPBU90 switch is designed to provide reliable, accurate control of pressurized media within applications. The benefits of using the SAPPBU90 pressure switch are that it is fast, reliable, and low maintenance.

SAPPBU90 applications include cooling systems, air compressors, condensers, biomedical systems, water flow systems, and fuel systems. It is a single-pole, single-throw (SPST) manual reset type pressure switch that can operate in temperatures ranging from -30 to +130°C and pressures ranging from 0.3 to 30 bar. Its durable construction ensures a long lifetime, even when subjected to harsh environments.

The working principle of the SAPPBU90 pressure switch is based on the operation of a direct action (DA) diaphragm. The diaphragm acts as a sensitive measuring element, which feels the pressure variation within the system. In normal operation, the DA diaphragm will be released when a preset pressure is reached within the system. The diaphragm will then actuate a control arm, which then triggers the switch contacts to open or close. This is used to regulate the system pressure by providing a warning signal when the pressure reaches certain thresholds.

The SAPPBU90 pressure switch is adjustable, allowing users to tailor the settings to their specific application. This can be done by adjusting the static and gain settings. The static setting is the adjustable limit, which sets the pressure at which the switch is activated, while the gain setting adjusts how sensitively the switch reacts to pressure changes. By controlling both of these settings, the user can easily tailor the switch to their specific application.

Overall, the SAPPBU90 switch is a reliable and accurate pressure switch for use in a wide range of applications. Its adjustable nature and DA diaphragm design enables it to provide fast and precise pressure control in all kinds of environments. By setting the static and gain settings appropriately, users can tailor the switch to work with their specific application.
