Company Case

Aerospace/Navigation/Military

Aerospace is a very important industry in people's modern life. It is not only an important means of transportation, but also an important and indispensable equipment for people to explore outer space.

Sensors also play a big role in aerospace, and each sensor in aerospace has different functions. To achieve flight control of an aircraft, the first thing to solve is how to accurately measure the various flight parameters of the aircraft, such as the aircraft's attitude angle, angle of attack, angular rate, overload, flight altitude and speed, oil level monitoring, etc. Therefore, various sensitive components have emerged, such as gyroscopes, angle of attack sensors, acceleration sensors, altitude sensors, oil level sensors, displacement and force sensors, etc.

The pressure, temperature and oil level sensors developed by Longlv in response to the particularities of the industry have been recognized by many well-known companies in the industry for their ultra-high precision, sensitivity and stability.

Medical Devices

Sensor technology is constantly optimizing its sensitivity, accuracy, reliability, stability and time drift, and is gradually being widely used in various medical respiratory devices, infusion pumps, insulin pumps, hospital diagnostic equipment and a variety of monitors. The flow, pressure and temperature sensors developed by Longlv Electronics are widely favored by units in the industry for their high sensitivity and accuracy.

Textile Machinery

As its eyes and nervous system, various sensors are the primary link to realize automatic detection and control, and are an important symbol of modern weaving technology. The characteristics of textile technology determine the sensitivity of textile equipment to sensors, and have high requirements for precision, which also determines the particularity of the application of sensors in engineering textile machinery and equipment. Longlv Electronics' pressure, temperature, displacement and other sensors are used in this industry with good sensitivity and high precision.
