The FE-N2 differential pressure transmitter is a specialized differential pressure monitoring and alarm component for hydraulic filtration systems. Its core relies on the principle of magnetic electric coupling to achieve precise triggering of differential pressure. The stainless steel integrated shell is rust resistant and corrosion-resistant, and is suitable for various conventional industrial hydraulic oil media. The preset alarm pressure difference is 0.35MPa, which can be adjusted as needed in the range of 0.1-0.5MPa. At the same time, it outputs visual pop-up indicators and electrical signal feedback, suitable for complex working conditions from -20℃ to 80℃. The standard threaded interface can be directly integrated into most conventional hydraulic filters to provide pre warning for filter blockage and ensure stable operation of the hydraulic system.
The FE-N2 differential pressure transmitter is a high-precision differential pressure monitoring and alarm component designed specifically for hydraulic filtration systems. It is a core protective component for controlling the status of hydraulic system filter elements and can sense changes in the pressure difference between the inlet and outlet of the filter element in real time. When the filter element is clogged to a preset threshold, it can output an alarm signal in a timely manner without the need for frequent manual disassembly and inspection of the filter element status, providing pre warning protection for the cleanliness and stable operation of the hydraulic system.

The FE-N2 differential pressure transmitter adopts an integrated compact structure design, and the core sensing unit relies on the principle of magneto electric coupling to trigger the differential pressure. The overall shell is made of stainless steel material, which has good rust and corrosion resistance and is suitable for various industrial hydraulic oil media. The preset alarm differential pressure is 0.35MPa, which can be flexibly adjusted within the range of 0.1MPa to 0.5MPa according to different system requirements. The working voltage is compatible with conventional 24V DC power supply, and some models can be compatible with 220V AC power supply. During operation, it can output visual pop-up indication and electrical signal feedback simultaneously. It can maintain stable triggering accuracy under complex working conditions with vibration amplitude ≤ 20m/s ² and ambient temperature of -20 ℃ to 80 ℃. The interface adopts standard thread design and can be directly integrated into most conventional hydraulic filters without Significant modifications are required to the existing pipelines.
The FE-N2 differential pressure transmitter can cover the monitoring scenarios of filter elements in various industrial hydraulic systems, and is suitable for monitoring the return oil filters of various machine tool hydraulic systems and engineering machinery hydraulic stations. It can also be used as a filter blockage warning device in hydraulic lubrication systems of metallurgical equipment and wind power equipment. At the same time, it is suitable for monitoring the status of pressure pipeline filters in injection molding machines and small power units. It can also be used as a core alarm component in the filtration units of ship hydraulic systems and mining hydraulic equipment, meeting the basic warning needs of hydraulic oil cleanliness control in different industries.
The FE-N2 differential pressure transmitter adopts a dual signal output design, which takes into account both on-site visual observation and remote electronic control signal feedback. The operation and maintenance personnel can quickly judge the status of the filter element through the pop-up indicator on site. The central control end can also synchronously receive alarm signals to achieve remote operation and maintenance reminders. The stainless steel shell greatly improves the environmental adaptability of the product. It is not easy to rust when used in humid and dusty industrial sites for a long time, and the triggering accuracy error is controlled within ± 5%, avoiding the occurrence of false alarms or missed alarms. The standardized interface greatly simplifies the installation and replacement process, and ordinary operation and maintenance personnel can complete disassembly and replacement without professional training. It has strong long-term stability and almost no additional maintenance costs in daily life.
If the transmitter does not reach the preset pressure difference and alarms in advance, priority should be given to checking whether the internal spring has fatigue deformation, adjusting the spring preload or replacing the corresponding accessories to restore accuracy; If the pressure difference has far exceeded the threshold but the transmitter has not been triggered, check whether the internal magnetic coupling components are stuck. After disassembling and cleaning the internal impurities, the normal triggering logic can be restored; If the visual indication has popped up but there is no electrical signal output, priority should be given to checking whether the external circuit wiring is loose. After confirming that the contacts are not oxidized or corroded, re connect the circuit to restore signal transmission; If there is oil leakage at the interface during operation, stop the machine to release pressure and replace the matching sealing components. Tighten the threads evenly to solve the leakage problem.
