dual needle air pressure gauge adopts a high-precision dual boden tube synchronous monitoring system, which allows the operator to simultaneously monitor two independent air sources (such as the main and auxiliary air tanks of the brake system) on a single dial. As a source manufacturer with more than ten automated production lines, Hangzhou East Asia Instruments (IMT) provides you with highly competitive direct supply prices and shorter delivery cycles through vertical integration of the supply chain and elimination of middlemen.
Application scenarios: mainly used in truck air brake system, air suspension adjustment, rail transit brake monitoring and industrial pneumatic circuit center.
through the precise nested shaft structure, the red and white pointers can display different air source pressures on the same dial, and the reading synchronization error is less than 0.5 percent, thus significantly improving the monitoring efficiency and response speed of the braking system.
the internal filling of high-viscosity glycerin or silicone oil, can absorb more than 95% of the system pulse and external violent vibration, prevent the pointer from shaking, and ensure that the reading is still clear and accurate in the driving of heavy commercial vehicles.
the pressure sensing element made of high-quality phosphor bronze material is cold-formed. After rigorous pressure cycle life test, its fatigue life is 30% longer than that of ordinary components, greatly reducing the frequency of equipment maintenance and replacement.
using fluorescent coating pointer or high contrast color design, even in the night driving or industrial light environment, the operator can instantly distinguish between the main and auxiliary pressure readings, to prevent the safety risk caused by misreading.
the joint and the shell are treated with double-layer sealing, and the leakage rate is controlled below 0.001 MPa per minute to ensure that the pneumatic system does not produce pressure relief when it is in a high pressure state for a long time, thus ensuring energy utilization efficiency.
the shell after electrophoresis or stainless steel polishing treatment, with strong resistance to salt spray and acid and alkali resistance, in the port, mining areas and other harsh conditions of continuous work for 5 years without rust, effectively protect the internal precision mechanism.

IMT dual needle air pressure gauge can save 50% of the dashboard installation space compared with the common single needle meter combination on the market. Through the precise coaxial processing technology, we solve the interference problem of the double needle in the cross movement, and ensure the high linearity and repeatability. In addition, the environmental tolerance of IMT products has been tested by extreme temperature differences in the laboratory, and the performance far exceeds that of similar primary products.
mainly for the vehicle design team of heavy trucks, buses and tractors, providing key pressure monitoring solutions for their air brake systems to meet international driving safety regulations and supporting requirements.
It is suitable for professional organizations that provide MRO maintenance services for logistics fleets and mine transportation vehicles. As a high-quality spare parts selection, it can effectively extend the attendance cycle of vehicles.
integrated experts for pneumatic control cabinets and large air compressors, optimize the operation interface through double-needle integrated design, reduce the complexity of system wiring and save space.
provide core monitoring components for the braking circuit of subway, train and other rail transit equipment to ensure real-time feedback of pressure data during frequent start-stop and high-speed operation of vehicles.
check whether the thread is complete before installation, and evenly wrap the raw material tape at the joint to ensure that it is tightly connected with the system pipeline to prevent debris from entering the pressure gauge during installation.
should choose a relatively small vibration of the location of vertical installation, the use of professional wrench tightening joints, it is strictly prohibited by hand tightening the case, so as not to cause internal mechanical linkage deviation.
When the pressure source is connected for the first time, the air source valve should be slowly opened to observe whether the two pointers rise smoothly. After confirming that there is no jam phenomenon, compare it with the standard pressure source for zero calibration.
it is recommended to check the accuracy every six months. If it is found that the pointer cannot be reset to zero, the dial leaks or the window is blurred, the manufacturer should be contacted in time for technical guidance or replacement of new products.
