The Application of Miran KTR Self-resetting Displacement Sensor in the Film Casting Machine
2026-09-29
In the plastic film and sheet production industry, the cast film machine is the core production equipment. During the production process, the precise control of the thickness of the cast film directly determines the quality of the product and the cost of raw materials. In the thickness control closed-loop system, the Miran KTR Self-resetting Displacement Sensor plays a crucial "eye" role.
The adjustment of the die head of the extrusion machine usually needs to be carried out in a complex environment with high temperature, narrow space and vibration. The traditional measurement methods often fail to achieve high-precision displacement feedback within the limited installation space. Moreover, when facing sudden mechanical stress, ordinary sensors are prone to damage, resulting in equipment shutdown for maintenance and affecting production efficiency.
To address the aforementioned issues, the equipment manufacturer selected the Miran KTR series self-resetting displacement sensor. As shown in the figure, this sensor is precisely installed on the fine-tuning mechanism of the extrusion machine die head.
The core advantages of the product as demonstrated in this case:
Ⅰ.Self-resetting function (key feature): The KTR series is characterized by its built-in self-resetting spring structure. During the operation of the extrusion machine, if the push rod is subjected to unexpected external lateral force or excessive travel, the sensor can automatically reset to its initial position, effectively preventing damage to the sensor caused by mechanical collisions, and significantly enhancing the durability and stability of the equipment.
Ⅱ.High-precision feedback: In the control of film thickness, even a micron-level error can result in uneven film thickness. The Miran KTR Self-resetting Displacement Sensor has high repeatability and linearity, and can promptly and accurately feed back the minute changes in the die gap to the control system, ensuring the uniformity of the film thickness.
Ⅲ.Durability and environmental adaptability: In the face of vibrations around the extrusion machine and certain temperature fluctuations, this sensor demonstrates excellent anti-interference capabilities, ensuring the reliability of long-term continuous production.
The Miran KTR Self-resetting Displacement Sensor, with its unique design and stable performance, has successfully overcome the measurement challenges in the thickness control of the casting machine. It is an ideal choice in the field of precise mechanical displacement measurement.
