Product Description

Water Pump/Boiler Factory Original Accessories Korean Auto Reset Pressure Controller

The Korean pressure controller pressure switch is a device used to monitor and control pressure. When the system pressure reaches the set upper or lower limit, the switch will automatically operate to achieve protection or control functions for the equipment.

Operating Principle:

The core operating principle of a pressure switch is to sense changes in system pressure through a "pressure-sensing element," convert the pressure signal into mechanical displacement or an electrical signal, and ultimately trigger the on/off action of the switch contacts, thereby providing protection, control, or alarm functions for the equipment. Essentially, it is a "pressure threshold-triggered controller" that activates only when the pressure reaches a preset upper (high) or lower (low) limit, rather than continuously monitoring the pressure value.

Classifications: 

Depending on the "pressure sensing element" and "signal conversion method", pressure switches are mainly divided into Mechanical type (pure physical trigger) and Electronic type (electrical signal trigger). The principles of the two are quite different and their applicable scenarios are also different. The following is an analysis of the core differences between the two.

Contrast Dimension	Mechanical Type Pressure Control Switch	Electronic Type Pressure Control Switch
Core Components	Elastomeric Diaphragm / Lever / Contacts	Pressure Sensor / MCU / Solid-State Relay
Triggering Method	Pure physical deformation actuation	Electrical signal comparison + electronic actuation
Accuracy	Low (±1%-5%)	High (±0.1%-1%)
Threshold Setting	Manual Screw/Knob (Mechanical Adjustment)	Button/Display/Remote (Digital Setting)
Applicable Environments	Resistant to vibration, dust, and oil (rough industrial environments).	Avoid strong electromagnetic interference (precision environments).
Summary:  Mechanical models offer durability and affordability, making them suitable for routine start-stop control. Electronic models offer precision and intelligence, making them suitable for high-precision, automated applications.
