KPZ is a miniature rod-type linear displacement sensor (also known as an electronic ruler/resistance ruler), belonging to the subdivision series of potentiometer-type displacement sensors. It is suitable for use in confined spaces, with excellent linearity and easy installation. Next, let's take a look at its suitable working environment, application scenarios, selection and installation points, and application advantages.

Linear sensors, also known as linear position sensors, are pivotal components in various applications requiring high-precision measurement of linear displacement. These sensors convert linear motion into electrical signals, enabling accurate tracking and control in industries ranging from automotive to robotics. This article delves into the key aspects of linear sensors, including their structure, types, and applications.

Linear displacement sensor is a kind of non-electric measurement sensor which is widely valued and applied at home and abroad at present. It consists of a heat-treated vibrating wire detection element, and a spring with one end connected to the vibrating wire and the other end connected to the sliding pull rod to eliminate stress. With the pull of the sliding pull rod, the spring begins to extend and causes the tension of the vibrating string to increase, and the vibration frequency of the steel string also changes, and the tension is proportional to the extension of the spring. Therefore, the change of displacement can be realized by measuring the tension of the steel string, that is, the change of the vibration frequency of the steel string.

Sensor is a kind of equipment that can sense environmental changes and automatically collect, process and transmit data. Intelligent agricultural machinery is mainly integrated in seeders, harvesters and other devices, supporting automatic driving and operation monitoring, and combining sensors and agricultural machinery equipment to realize the automation and intelligence of agricultural machinery operation. For example, using the controllability of sensors to ensure the accuracy of the driving path of agricultural machinery and avoid the collision of agricultural machinery at high speed and damage to agricultural products.
