Characteristics of MINOR linear position Sensors
With the joint efforts of engineers and technicians of our Company, the MINOR series products have been continuously improved. According to the practical testing of customers and relevant departments in the past half decade, our products have reached international advanced level for performance and quality and enjoy high reputation in the industry.
MINOR displacement sensor is composed by five parts:
I. Aluminum shell. Surface anode electrophoresis treatment, champagne exterior, internal structure design through finite element analysis, high strength and outstanding bending resistance capacity and torsion strength. MINOR series products not only have smooth appearance, exquisite handle but also have strong corrosion resistance that can be applied for field operation in the absence of external protection.
II. Multi-touch wiper. We use rare metal wiper materials and adopt the world's top class mounting technology that mounts a piece of 0.3mm thick high-wearing-resistant and corrosion-resistant rare metal with outstanding conductive property (known as the metal diamond in the world) on the 0.07mm thick base material, effectively enhancing the wearing resistance and conductive property of the wiper. The multi-finger design enables the wiper to have high elastic energy and intensity simultaneously and also ensures the consistently good contact with the resistance substrate in the vibration condition. The safety design idea of multi-finger enables the always stable contact resistance of MINOR products which lays a solid foundation for improving the product linearity.
III. Resistance track.. Resistance track is the most important component of the sensor that is the bottleneck determining the product performance and quality. The operation mechanism of the resistive sensor determines that the resolution of the product is infinitesimal. MINOR has abandoned the traditional carbon film resistor and has adopted the military-level conductive plastics technology. The resistance track of a large number of displacement sensors in the market are printed circuit in the nature so that the operating temperature can not exceed 90 ¡æ. The wearing resistance of the conductor carbon film of printed circuit is inadequate. After a period of operation, heavy wear and tear will be caused which will not only change the initial resistance and reduce the smoothness of the output signal, but will also result in unstable output signal, significant noise when sampling and great reduce of linearity caused by toner attached to the wiper. The ultra-wear-resistant conductive plastics technology of MINOR has thoroughly overcome these drawbacks. Our conductive plastic resistance substrate is made by thermal polymerization molding technology at the high temperature of 200 ¡æ and has gone through the 96 hours aging treatment at 170 ¡æ so that the one hundred million times of operation of the product can be guaranteed as the linearity and smoothness will not be reduced. Since the initial precision of the resistance track is comparatively low, the requirements of high precise industry can not be met. It is necessary to amend and compensate the linearity of the resistance substrate. MINOR has the exclusive domestic advanced linearity amending technology which ensures that out products can reach the 0.03% output linearity to the utmost.
IV. Stainless steel rod. Rods are flexibly connected. Use universal joint or ball pivot to compensate for part of the installation angle, reducing the accuracy requirements of the installation and allowing a certain installation deviation angle.
V. Shaft seal ring. Shaft seal ring is the main factor determining the product protection level. The biaxial shaft end sealing technology is adopted and the material has strong oil-proof and wearing resistance properties with good tightness so that the anti-dust, anti-oil and water-proof effects can be achieved by our products. Some products can even reach the IP65 protection property. In the meanwhile, the flexible shock absorption technology is applied to effectively buff and absorb the strong vibration occurred in the operation process of the displacement sensor.
