3100 Pressure Transmitter Applied in Engineering Construction Machinery
The 3100 Series Pressure Transmitters are part of the company's Gems brand, a pressure sensor for the new generation of sputter-film technology that is especially introduced for OEM users and volume users. On the mature application and technology platform, a lot of research has been done on the OEM market, and efforts have been made to make the latest improvements to the manufacturing process and production technology, so that the product has different performance of any previous product, while at the same time meet the global goals Increasing customer demand for reduced procurement costs.
Engineering construction machinery and other OHV (Off-Highway-Vehicle) applications are one of Gems' strategic markets. Its hydraulic systems generally have high working pressure, frequent work, strong transient pressure shock, large mechanical vibration, and compact installation space. , And due to the extensive use of the host computer, it may be under extreme temperature and climatic conditions, and it requires a higher temperature index of the sensor. More importantly, the user's demand for reliability of construction machinery and reduced maintenance costs make the long-term stability of sensors one of the key indicators.
The pressure transmitter has been designed in advance to take into account the requirements of these practical applications, and its indicators can fully meet the harsh conditions. For example, long-term stability and temperature stability, in fact, after 10 million cycles of operation, the maximum drift of several sets of test sensors is only 0.03% FS, in the temperature of 125 degrees Celsius, continuous operation for 500 hours, the drift is less than 0.05 %FS, another practice shows that under an operating pressure of 400 bar, applying an alternating temperature, its maximum drift is no more than 0.01% of full scale. Due to the influence of the internal structure, the general sensor tends to be unstable, requiring 6-12 months of calibration, while the 3100 series can reduce the number of calibrations, thereby reducing the cost of use and improving work efficiency.

For high pressure applications in construction machinery (eg 400 bar), the 3100 pressure transmitter's wide range (up to 2200 bar) can fully meet its requirements. In particular, for heavy-duty type 3200 series pressure transmitters that are based on pressure surges like 3100, the overvoltage protection capability is 4 times full scale. In particular, if pressure limiting damping is added, it can be completely Avoid direct pressure on the diaphragm, while at the same time almost no increase in response time, and more pressure shock protection of the sensor.
On the other hand, the mechanical vibration performance of up to 40G is particularly suitable for engineering construction machinery that is often used in jolting occasions. Even though it is not easy to occur, the sensor can still work normally even in the extreme case of falling from a height of 2 meters. This feature is closely related to the close cooperation and complete alignment design of the components inside the 3100/3200 pressure transmitter. The compact structure makes it have good mechanical properties. Its all stainless steel laser welded package structure not only enhances the overall strength, but also basically eliminates the possibility of leakage and adapts to various environmental conditions.
It is particularly important to point out that because of the unique temperature compensation design, the 3100 Series Pressure Transmitters can have the function of temperature output at the same time. In other words, a single sensor can combine both pressure and temperature output with a temperature range of -40 to 125 degrees Celsius. In a specific situation, it can save customers a temperature sensor, which greatly reduces the cost.
The compact structure of the 3100 pressure transmitter makes it suitable for most narrow spaces. For example, a sensor with a DIN plug has an overall length of approximately 45 mm, which facilitates the designer's work on component placement.
The above description is only for some application features of construction machinery, and 3100 pressure transmitters face the market, including construction machinery, medical equipment, refrigeration and air conditioning, air compressors, plastic machinery, water supply systems, common rail systems, General hydraulic systems and equipment, and other occasions where the performance and price of the sensor are quite demanding.
