What is a linear displacement sensor KTR?
KTR linear displacement sensor (especially miniature self-recovery series) is a kind of high-precision measuring element specially designed for narrow space and harsh environment, with automatic spring reset function. The following are its main application fields and characteristics:
KTR series sensors adopt the principle of potentiometer, and belong to miniature self-restoring (self-resetting) linear displacement sensors.
Mainly has the followingcharacteristics：
1.Compact structure: small size, suitable for space-limited occasions
2.Self-recovery function: Built-in return spring, the measuring rod automatically rebounds after being pressed to ensure the continuity of measurement.
3.Long life: key components can withstand 30 million reciprocating motions.
4.Protection grade: IP65, the shell is anodized, corrosion-resistant, dust-proof and oil-proof.
5.Flexible output: it supports resistor output (2kΩ, 5kΩ), voltage (0-5V/0-10V), current (4-20mA) and digital signal (RS485).
6.High accuracy: the linear accuracy can reach ±0.1%FS, and the repeatability accuracy is 0.01 mm.
Main application fields:
1.Plastics and packaging machinery:
Hollow bottle blowing machine/blow molding machine: accurately control the position of the mold to realize the monitoring of product molding quality.
Printing and paper packaging: used for deviation correction system, die-cutting position control and feeding length detection.
2. Metal processing and automation:
Automatic feeder of high-speed punch: adjust the feeding speed and position
Tension control system: real-time monitoring of material tension changes.
Manipulator positioning: used for manipulator joint feedback and fixture positioning of small and medium-sized automation equipment.
3. Measuring and testing equipment
Size measurement: mechanical parts size, fruit size and rod diameter measurement.
Flatness detection: automatic flatness detection of metal plates.
Material testing machine: accurate measurement of small displacement Tape casting machine: vertical and horizontal displacement measurement and control
4. Medical and laboratory equipment
Displacement feedback of high-precision instruments such as pipettes and microscope stages
5.Construction machinery and agricultural machinery
Small hydraulic actuator position feedback, control handle displacement detection, sowing depth adjustment
6.IT and electronic manufacturing
Automatic screw machine: accurately detect screw displacement and realize locking automation. Other IT equipment requiring compact installation.
Main points of installation and use:
Installation direction: the conductive circuit board should be installed face down or upright, and it is forbidden to go up to avoid impurities affecting stability.
Reserved allowance: the measuring range should be greater than the actual stroke when selecting the model, and the allowance should be evenly left at both ends.
Alignment adjustment: it is necessary to ensure good alignment, and a universal joint should be installed when the deviation is large.
Power supply requirements: the power supply voltage should be stable (industrial power supply 0.1%) and the capacity should be sufficient.
Fixation method: it can be installed sideways or vertically, and it needs to be fixed with special brackets and screws.
KTR sensor solves the pain point of displacement measurement in compact space, high-frequency movement and harsh environment through the combination of "small size+self-reset design+solid protection", which helps equipment to improve performance and reduce maintenance costs.
KTR linear displacement sensor is especially suitable for industrial automation scenes with narrow installation space, automatic reset, harsh environment and long service life, and it is outstanding in plastic machinery, printing and packaging, metal processing and other fields.
