III FF 4-60 PAHProduct Introduction

FF 4-60 PAHbelong toFF4The high-pressure models in the series use plastic plungers as pressure sensing elements. It is designed to monitor the pressure of liquid or gas media and drive electrical contacts to switch when the pressure reaches a preset value, thereby controlling the start and stop of pumps, compressors, and other equipment or issuing alarm signals.

Working Principle:

The pressure switch is a purely mechanical structure. The system medium pressure acts on the plastic plunger. The displacement of the plunger is transmitted and amplified through a set of lever and spring systems, ultimately driving a fast motion with high anti vibration performance（snap-action）Cascade switch. This design ensures that the switch operates quickly and decisively, avoiding contact shaking at critical points (no vibration switching).

Its circuit is a conversion contact（Change-over contact）Design, usually marked as1-2and1-4For example, when there is no pressure in the system or the pressure is lower than the lower switching point, the contact point controls the water pump1-2Closed, can be connected as the starting signal for the pump; When the pressure rises above the upper switching point, the contact point1-2Disconnect while contacting1-4Close and issue a stop pump or alarm signal; When the pressure drops below the lower switching point again, the contact point1-2Close again and prepare for the next work cycle. The up and down switching points can be independently adjusted with a screwdriver, and the set value can be indicated on the scale inside the device.

4 Core Features

Ø Independent dual point adjustment and clear indication: The up and down switching points can be adjusted independently, providing users with flexible pressure control bandwidth settings. The adjustment point is indicated by the mechanical scale inside the device, and the reading is clear and intuitive.

Ø Sturdy structure and high adaptability: The main structural components are made of die cast aluminum alloy base, and the pressure interface is made of stainless steel material, which enhances the overall durability and corrosion resistance.FF 4-60 PAHThe model comes standard with a throttle valve, which can be used for gentle pressure shock; When facing high viscosity media, this throttle valve can be removed, reflecting its adaptability to different working conditions.

Ø Stable mechanical performance: using leverage-The combination mechanism of spring and quick action switch gives it good anti vibration performance, high repeatability of switch action, and helps to ensure the stability of the control system.

Ø Convenient installation and wiring: The product design provides ample wiring space for easy electrical connection. The transparent polycarbonate cover can provide protection for internal mechanisms (with a protection level of up to)IP54/IP65）It is also convenient to observe the contact status and rough scale without opening the casing.

5 application field

Based on its reliable pressure monitoring and control capabilities,FF 4-60 PAHAnd its affiliatedFF4The series is suitable for multiple industrial fields:

Ø Fluid power system: widely used for pressure monitoring and control of air compressors and hydraulic systems, ensuring that the system operates within a safe pressure range and achieving automatic start stop of equipment.

Ø Water supply and drainage and fire protection system: used to control water pumps, booster pumps, as well as pressure monitoring of fire water supply pipelines and sprinkler systems, ensuring stable water supply and reliable emergency response.

Ø Industrial equipment auxiliary system: used to monitor the pressure of cooling circulation circuits and lubrication systems of various mechanical equipment, to prevent equipment overheating or wear caused by pressure deficiency.

Ø Ship and Ocean Engineering: This series includesGLModels certified by the German Lloyd's Register of Shipping, specifically suitable for the starting air system and fuel of ships/The lubricating oil system and ballast water system can adapt to high salt spray and high vibration conditions in marine environments.

Ø Process industry: In the fields of chemical engineering, food processing, etc., it is used to monitor the pressure of liquid or gas media in pipelines, storage tanks, and pressure vessels, and is a commonly used component for process control and safety interlocking.
