The pull rope displacement sensor is especially suitable for linear guide rail system, hydraulic cylinder system, testing machine, telescopic system (forklift, press, elevator, pipe bender, bender, etc.), crane or cable winch, reservoir dam protection system, gate opening control system, testing machine pressure machinery, hydraulic universal experimental machinery, storage position positioning, pressure machinery, paper-making machinery, textile machinery, sheet metal machinery, packaging machinery, printing machinery. Construction machinery, horizontal controller, construction machinery, industrial robot, injection machine, woodworking machinery, elevator, air compressor/hydraulic press, height machine, X-Y axis and other length displacement, etc., dimension measurement and position control, especially suitable for the control of electro-hydraulic servo hydraulic universal testing machine.

Draw wire sensor is also called rope ruler and rope encoder. Its working principle is very simple, that is, the wire rope at the outlet of the sensor is pulled, in which the wire rope is wound on a pulley built in the sensor. When the wire rope is pulled, the other end of the sensor is connected to the mechanical motion, and a display is installed on it to convert the mechanical motion into an electrical signal to obtain the required data. In operation, the pull rope displacement sensor is installed at a fixed position, and the pull rope is tied to the moving object. The linear motion of the pull rope is aligned with the motion axis of the moving object. When the movement occurs, the rope stretches and contracts. An internal spring ensures that the tension of the pull rope is constant. The threaded hub drives the precision rotation sensor to rotate, and outputs an electrical signal proportional to the moving distance of the pull rope. The displacement, direction or velocity of the moving object can be obtained by measuring the output signal. Commonly used parameters include measuring stroke, output signal mode, linearity, repeatability, resolution, wire diameter specification, outlet tension, maximum round-trip speed, weight, input resistance, power, working voltage, working temperature, vibration, protection level, etc.

Common pressure sensors include resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, positive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor, capacitive acceleration sensor, optical fiber pressure sensor and so on. Piezoresistive pressure sensor is the most widely used pressure sensor, which has the characteristics of low price, high precision and good linearity.

Pressure sensor is the most widely used sensor, which is used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent building, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.

The working principle of linear displacement sensor is the same as that of sliding rheostat. It is used as a voltage divider, and it presents the actual position of the measured position with relative output voltage.

For the inspection of automobile parts, the size inspection should be the most important, and LVDT displacement sensor (differential transformer displacement sensor) must be used to detect and control the size. As a displacement sensor with strong environmental adaptability, high precision and durability, LVDT displacement sensor is the first choice in parts inspection system. So what is the specific application of LVDT displacement sensor in automobile parts inspection?

The advantages of LVDT mainly include: non-contact principle, good wear resistance, high resolution, good repeatability, no sliding contact and long service life; Fast response speed; High linearity; Good repeatability; Wide range coverage; Low fault/low power consumption/diversity of input and output; Good dynamic characteristics, can be used for high-speed online detection, automatic measurement and automatic control; Can be used in harsh environments such as humidity and dust; Can work under special conditions, such as high pressure resistance, high temperature resistance, radiation resistance, full-tight soil seal working underwater; It can withstand impact up to 150g/11ms, vibration frequency 2KHZ acceleration 20 g; Small size, low price and high performance-price ratio.

Inductive proximity sensors are widely used in industrial automation, robotics, machinery manufacturing and other fields. For example, in the automatic production line, sensors can be used to detect the position, existence and motion state of the workpiece, so as to realize the automation and intelligence of the production process. In addition, it can also be used to detect the speed of sprocket teeth in textile, chemical fiber, machine tool, machinery, metallurgy, locomotive and automobile industries, the speed and distance of chain conveyor belt, and the control of automobile protection system.

The working principle of a linear displacement sensor is to use a variable resistance slide rail structure. When the slide moves on the slide rail, the resistance value changes. By measuring the voltage difference between the slide rail and the fixed end, combined with the total resistance of the slide rail, the displacement can be calculated.
