YA00004499 SWITCH For HITACHI ZW220-5A QSB6.7

The working principle of pressure switch is to realize the purpose of automatic adjustment and control by sensing the system pressure and sending out control instructions. Pressure switch usually consists of three parts: sensor, actuator and control unit. The sensor is responsible for detecting the pressure in the system, the actuator acts according to the instruction of the control unit, and the control unit is responsible for receiving the sensor signal and sending out the control instruction. According to the working principle, pressure switches can be divided into mechanical and electronic types. Mechanical pressure switch drives mechanical structures, such as valves, pistons, etc., by sensing the pressure change, and realizes the switching action. The electronic pressure switch collects pressure signals through sensors, and then processes, analyzes and controls them through electronic components. Pressure switch has the advantages of simple structure, convenient operation and high reliability, so it is widely used in many industrial applications. It can automatically adjust the running state of equipment according to the change of system pressure to ensure the stable operation of the system.

A pressure switch, also known as a pressure sensor or pressure control switch, is a device used to detect and control the pressure within a system. It is designed to activate or deactivate a circuit when a preset pressure level is reached, typically used in hydraulic, pneumatic, and automotive systems. The switch ensures that the system operates within safe pressure ranges, providing protection against overpressure or underpressure conditions. The switch knob or switch actuator allows for manual adjustment or setting of the desired pressure threshold.Key functions include pressure monitoring, system protection, and automation control. It is commonly used in applications such as compressors, pumps, and heating/cooling systems.

Pressure Switch is a device that can automatically monitor and control the pressure change of fluid or gas, which is widely used in industrial production and civil fields. Its main function is to automatically control the start and stop of equipment by sensing the change of pressure, so as to achieve the purpose of controlling the pressure of equipment. Pressure switch detects the change of pressure through sensing elements (such as diaphragm, microswitch, etc.). When the controlled equipment is running, the sensing element of the pressure switch will sense the pressure change of fluid or gas, so as to judge whether the equipment needs to be started or stopped. Specifically, when the pressure of the equipment is lower than a certain value, the pressure switch will automatically start the equipment; When the pressure of the equipment reaches a certain value, the pressure switch will automatically stop the equipment.
