Marine And Automobile Pressure Gauge Manufacturers

What are the requirements for the installation environment of marine and automobile pressure gauge?

In the application of Marine And Automobile Pressure Gauge, the control of temperature and humidity is the basis for ensuring the stability of instrument performance. The pressure gauges produced by JRL are designed with the applicable range of ambient temperature in mind, and are recommended to be used under conditions of -40℃ to 60℃. The selection of this temperature range is based on our in-depth understanding of material science and strict control of precision manufacturing processes. Too high a temperature will accelerate the aging of the internal components of the instrument, thereby affecting the accuracy of the measurement; while too low a temperature may cause the embrittlement of the material, significantly increasing the risk of instrument damage. At the same time, the relative humidity should be controlled below 80% to prevent the humid environment from causing problems such as circuit short circuits or corrosion, thereby affecting the normal operation of the instrument.
In marine and automotive applications, vibration and shock are inevitable external factors. In order to ensure the measurement accuracy of the pressure gauge and extend its service life, JRL fully considered these environmental challenges during the design process of the product. Our pressure gauge adopts a vibration-resistant and shock-resistant structural design, which can effectively resist the influence of external vibration on internal components. However, in actual installation, it is still necessary to avoid installing the pressure gauge directly near the vibration source, such as an engine or pump, to reduce unnecessary vibration interference. In addition, it is crucial to ensure that the instrument is firmly fixed to prevent loosening caused by bumps during vehicle driving or ship sailing.
Cleanliness and sealing are important requirements when installing Marine And Automobile Pressure Gauge. Keeping the installation environment clean can effectively prevent impurities, dust or moisture from entering the instrument and affecting its normal operation. Therefore, before installation, the installation location should be thoroughly cleaned and the sealing performance of the instrument should be checked to see if it is intact. JRL's pressure gauge uses high-precision sealing technology to maintain good sealing even in harsh environments. During installation, it is crucial to use suitable sealing gaskets and fasteners to ensure that the connection between the instrument and the pipeline or equipment is tight to avoid any possible leakage.
The selection of pressure points and pipeline layout are crucial to improving the measurement accuracy of the pressure gauge. In marine engineering, the pressure point should be selected in the straight pipe section where the measured medium flows, avoiding the bends, bifurcations or dead ends of the pipeline to reduce the interference of eddy currents and turbulence on the measurement results. In the automotive industry, it is also necessary to ensure that the pressure point is perpendicular to the flow direction to reduce dynamic pressure errors. In addition, the design of the pressure pipe should be reasonable, the inner diameter is generally 6-10mm, and the length should be as short as possible to reduce the delay of pressure indication. When the measured medium is easy to condense or freeze, it is recommended to set up an additional insulated heating line to prevent blockage, thereby ensuring the normal operation of the pressure gauge.

What details should be considered in the material selection of marine and automobile pressure gauge

In today's industrial field, the pressure gauge is a key measuring tool, and its material selection directly affects its performance and application range. JRL deeply understands this and is committed to providing customers with high-performance pressure gauges, especially in terms of corrosion resistance, temperature resistance, pressure resistance, machinability and economy.
First of all, corrosion resistance is an important consideration for the selection of pressure gauge materials. In the marine environment, the high salinity of seawater and its corrosiveness pose a severe challenge to the material of the pressure gauge. In response to this problem, JRL gives priority to corrosion-resistant materials such as stainless steel and titanium alloy. Stainless steel is widely used in general seawater pressure measurement due to its excellent corrosion resistance, wear resistance and high strength. Titanium alloy, with its light weight, high strength and excellent corrosion resistance, has shown great value in deep-sea exploration and scientific research, and can maintain excellent performance in marine environments as deep as thousands of meters.
In the automotive industry, although the corrosive environment is relatively mild, considering the complexity and diversity of the vehicle operating environment, JRL still recommends the use of corrosion-resistant materials such as stainless steel or titanium alloy to ensure the long-term stable operation of the pressure gauge under various conditions.
Secondly, temperature resistance is another key factor affecting the performance of the pressure gauge. In high-pressure and high-temperature industrial environments, the material of the pressure gauge must be able to withstand extreme temperature changes. JRL has fully considered this in the selection of materials and recommends the use of materials that can withstand high temperatures, such as stainless steel and certain special alloys. These materials not only have excellent corrosion resistance, but also can maintain stable mechanical and chemical properties under high temperature conditions, thereby ensuring that the pressure gauge readings are accurate and reliable.
In addition, pressure resistance is an indispensable element in the design of a pressure gauge. As a tool for measuring pressure, the material of the pressure gauge must have sufficient strength and toughness to withstand the pressure of the measured medium. JRL strictly follows industry standards and specifications to ensure the stability of the selected materials under high-pressure environments. At the same time, by optimizing the structural design of the pressure gauge, its overall pressure resistance is improved to ensure reliable operation under extreme pressure conditions.
In addition to considering the performance of the material, JRL also pays attention to the machinability and economy of the material. Materials such as stainless steel and titanium alloy not only show excellent performance, but also have good machinability, which is convenient for manufacturing and processing into pressure gauges of various shapes and sizes. The price of these materials is relatively reasonable, which can effectively reduce the customer's procurement cost while ensuring performance.
Finally, for specific application needs, JRL provides customized material selection solutions. In special environments such as deep-sea exploration and high-temperature and high-pressure vessel monitoring, the material requirements for pressure gauges are particularly strict. For example, in deep-sea exploration, it is recommended to use lightweight and high-strength materials such as titanium alloys to reduce the overall weight of the instrument and facilitate carrying and installation; while in high-temperature and high-pressure vessel monitoring, it is recommended to use special alloy materials that can withstand extreme temperatures and pressures to ensure the safety and reliability of the instrument.
