Application of the Miran Linear Displacement Sensor WDL in Metal Cutting Machines
2026-08-29
The processing accuracy of metal-cutting machines fundamentally depends on the precise control of the relative position between the tool and the workpiece. The Miran linear displacement sensor, as the core component for detecting this critical displacement, its performance directly determines the positioning accuracy and processing quality of the machine.
Core measurement principle
Miran WDL small pull rod type linear displacement sensor (also known as resistance ruler, potentiometer, displacement sensor) principle: Based on the potentiometer principle. All sensors are position measurement type, used in the control system (control device) and measurement system to directly measure displacement and length, output a DC voltage signal. It can also be converted into standard 0-5V, 0-10V or 4-20mA DC signals through built-in or external V/A conversion module, and can also be transmitted over a long distance for control requirements. WDL small lever-type electronic ruler (also known as resistance ruler, potentiometer, displacement sensor) output displacement change: 0-100% of the given input working voltage (changes with displacement).
Installation scenario analysis
1.Real-time position feedback: When the drive cylinder or servo mechanism of the metal cutting machine moves the platform, the pull rod of WDL will simultaneously extend and contract, generating an electrical signal proportional to the displacement.
2.Closed-loop control: The collected analog signals will be sent to the control system, where the closed-loop control logic is executed. This automatically calibrates the relative position between the tool and the workpiece, ensuring the accuracy of repeated positioning.
The Miran WDL small pull rod type linear displacement sensor is of general versatility and is suitable for position detection of various types of equipment, such as injection molding machines, die-casting machines, rubber machines, shoe machines, EVA injection molding machines, blow molding machines for hollow bottles, woodworking machinery, hydraulic machines, etc.
