All involved in earthwork construction, road construction and maintenance, mobile lifting and loading operations and various types of construction projects required by the comprehensive mechanization of construction projects rely on mechanical equipment, are collectively referred to as construction machinery. In view of the construction machinery often need to work in a relatively harsh environment, in order to effectively improve its work safety and overall performance, it is necessary to carry out accurate and effective control of the overall performance of the machinery.

In recent years, with the rapid progress of construction machinery manufacturing technology, Firstrate sensor technology in the field of construction machinery is more and more common and in-depth application. Products mainly cover pressure, temperature, oil level, displacement, wind speed and direction, etc. Sensors in construction machinery, the main role of the sensor is all kinds of non-electric signals in accordance with a specific law is converted to power output, in order to analyze and process these signals, and accordingly adjust the working state of the controlled device. At this stage, the sensors used in construction machinery are mainly used in three aspects: one is the precise control of the engine conditions; the second is the effective management of the hydraulic system; the third is the overall performance of the construction machinery comprehensive monitoring.
