With the continuous development of technology, the importance of sensors and harness in construction machinery applications is increasingly prominent. This article will introduce the basic knowledge of sensors and harness and their applications in the field of construction machinery, so as to help readers better understand the trends in this field.

I. Sensors Overview

A sensor is a detection device that can sense the specified physical quantity and convert it into an output signal. Sensors play an important role in construction machinery, such as monitoring the working state of hydraulic systems, measuring oil cylinder displacement, detecting engine speed, etc. There are various types of sensors, which can be selected according to different application requirements, such as pressure sensors, displacement sensors, temperature sensors, etc.

II. Harness Overview

Harness is an assembly of wires used to connect controllers,actuator, sensors, and other components. Harness plays a crucial role in construction machinery, providing the necessary power and signals for mechanical equipment. Harness can be classified according to their function, specification, material, etc., such as high-temperature-resistant harness, waterproof harness, aluminum harness, etc.

III. Application Scenarios

Sensors and Harness have a wide range of applications in construction machinery, some typical application scenarios include:

1. Hydraulic System: Sensors can monitor the flow and pressure of hydraulic oil to ensure the system's normal operation. Harness is used to transmit power and signals to ensure that hydraulic pump stations and control valves work properly.

2. Excavator: Sensors can detect the position and angle of the shovel to achieve precise control. Harness is used to connect sensors on the shovel with the control console to ensure normal operation of the mechanical equipment.

3. Crane: Sensors can monitor parameters such as lifting weight and lifting height to ensure safe operation. Harness is used to connect sensors with the control box to ensure normal operation of the crane.

IV. Performance Comparison

In terms of performance, sensors and harness both have certain requirements in construction machinery applications, some of which are:

1. Accuracy: For some applications, sensors need to have high accuracy, such as measuring the flow and pressure of hydraulic oil. The accuracy of harness mainly depends on the connected equipment, generally with higher requirements.

2. Durability: Both sensors and harness need to have high durability in construction machinery applications, able to withstand harsh working environments.

3. Reliability: The reliability of sensors and harness is crucial for the normal operation of construction machinery.

4. Cost: The cost of sensors and harness is also a consideration. In some cases, a trade-off between performance and cost needs to be made when choosing suitable sensors and harness.

V. Conclusion

Sensors and Harness play a crucial role in construction machinery applications, and are essential for the maintenance of mechanical equipment. With the continuous advancement of technology, the performance of sensors and harness will continue to improve, providing stronger support for the development of the construction machinery industry. In the future, we can expect sensors and harness to become more intelligent and precise, bringing greater benefits to construction machinery applications.
