In fields such as industrial automation and precision manufacturing, displacement sensors are core components for achieving precise control and monitoring. GRAEFF's GD series displacement sensors, with their outstanding performance, have become the "precise perception core" for many devices.

Product advantages: Precise and reliable, with outstanding performance

The GD series displacement sensor, also known as the linear displacement sensor, is a linear device that belongs to metal induction. It can accurately convert various measured physical quantities into electrical quantities and has many advantages:

High-precision performance: Independent linearity reaches ±0.1%, repeatability reaches 0.01mm, capable of achieving micron-level displacement measurement, providing strong data support for high-precision control of equipment.

Flexible adaptability: The resistance tolerance covers specifications such as 2KΩ and 5KΩ, and the mechanical stroke can be adjusted within a range of + 3mm, meeting the displacement measurement requirements of different equipment.

Strong environmental adaptability: The maximum working speed can reach 10m/s, capable of handling high-speed movement scenarios. The operating temperature range is -60 ℃ to +150℃, and it can work stably in extremely high and low temperature environments. The temperature drift is extremely small, and the data stability is strong over long-term use.

High-sensitivity adjustment: The sensitivity can be adjusted within the range of 0-100% according to the displacement, which can keenly capture subtle displacement changes and assist in the precise control of the equipment.

Application fields: Multi-scenario coverage, empowering industry development

The GD series displacement sensors, with their outstanding performance, are widely used in the following fields:

Injection Molding Machines

As a core equipment for plastic molding processing, injection molding machines have extremely high requirements for mold opening and closing accuracy and injection volume control. The GD series displacement sensors can accurately monitor the displacement of two key links: first, installed in the mold opening and closing mechanism, it can capture the mold closing displacement in real time to ensure that the mold is accurately connected to the preset position, avoiding material leakage due to insufficient closing or mold collision damage caused by excessive closing; second, assembled at the injection piston drive end, it dynamically tracks the piston propulsion displacement, accurately calculates the injection volume through displacement data, prevents product flash caused by excessive injection and product lack of material caused by insufficient injection, and provides reliable displacement data support for injection molding machines to stably produce high-quality plastic parts (such as electronic casings, automotive plastic accessories).

Machinery and machine tool equipment

In various mechanical devices and machine tools, precise detection of component displacement provides support for the automated operation of equipment, fault monitoring and high-precision processing, and improves the processing accuracy and quality of parts. Like precision grinding machines, by relying on their precise monitoring of grinding wheel displacement, they can process workpieces with extremely low surface roughness.

Hydraulic and pneumatic transmission equipment

Detect the piston displacement of hydraulic and pneumatic cylinders to achieve precise control of the transmission process, such as controlling the opening and closing displacement of molds in injection molding machines and die-casting machines to ensure the quality of product molding. On large hydraulic presses, the displacement of the press head can be monitored to ensure the dimensional accuracy of metal forged parts.

Construction machinery

On equipment such as excavators and cranes, monitor the displacement of components like mechanical arms and buckets, assist operators in precisely controlling equipment movements, and enhance construction efficiency and accuracy. On a bulldozer, the lifting and lowering displacement of the bulldozer blade can be detected to precisely control the amount of soil being pushed.

Medical equipment

In medical imaging equipment and surgical instruments, precise measurement and control of the displacement of precision components are achieved, providing a guarantee for the accuracy of medical diagnosis and surgical operations. For instance, in an MRI device, the displacement of the scanning bed can be monitored to ensure that the patient is precisely in the scanning area.

Construction equipment

Monitor the displacement of key components of construction machinery such as tower cranes and concrete pump trucks to ensure the safe and stable operation of construction equipment during the construction process. In elevator equipment, it can detect the displacement of the car, achieve precise leveling, and enhance the riding experience and safety.

The field of robotics

Provide displacement feedback for the joint movement and end effector action of industrial robots and service robots, enabling the robots to precisely complete actions such as grasping and assembly. For instance, a catering service robot can rely on it to control the displacement of the plates held by the mechanical arm to deliver food smoothly.

Automated processing equipment

In automated production lines, laser cutting machines and other equipment, precisely controlling the displacement of processed components enables automated and high-precision processing and production, enhancing production efficiency and product quality. On the electronic component placement machine, the displacement of the placement head can be precisely controlled to accurately mount tiny components onto the circuit board.

Aerospace equipment

In the tooling equipment for aircraft manufacturing, the displacement of wing and fuselage components during the assembly process can be detected to ensure the precise assembly of each component of the aircraft and guarantee flight safety. In the satellite ground test equipment, the displacement of the satellite simulation cabin can be monitored, providing a precise environment for satellite testing   

Rail transit equipment

 In the braking systems of subways and high-speed railways, the displacement of brake shoes and wheels can be detected to achieve precise braking and ensure driving safety. On the track detection vehicle, the displacement of the detection device can be monitored, and data such as the flatness of the track can be accurately obtained.

GRAEFF's GD series displacement sensors, with their precise perception capabilities and outstanding performance, have become a key driver for intelligent and high-precision operation of equipment in various fields, promoting the efficient development of the industry.
