Draw wire encoder design principles:
Draw wire encoder is composed of a group of spring-type wire spring mechanism combined with a rotary encoder or potentiometer, mainly used in linear displacement, length cutting, tension control, level control, speed control and other related automatic control measurement.
Product Features:
Mechanical space is too small or measuring the trip is too long Easy to install optical ruler and rotary encoder space for the length of the trip Measurement resolution requirements between 1-0.1MM automatic mechanism can be directly connected with an empty hydraulic cylinder, slide or other linear motion mechanism, the use of this product can reduce the installation space and the cost of the machine about 30% Installation Linear angle tolerance allows large (+/- 2 ~ 3 degrees)
For related products industry or machine name:
Speed control --- plastic injection molding machine, aluminum extrusion type extruder
Tension control ---- rubber extrusion thickness control, cable extrusion control
Displacement Length ---- XY table, air hydraulic mechanism, the length of the machine cutting, feeding rod feeder control, large metal materials (such as planer or stone cutting), radar or observatory displacement angle control, Boiler heart precise micro-displacement control, plotter displacement measurement.
Height Measurement - Reservoir gate opening control, level measurement, drilling machine blind hole depth control, object height or crane height control.
