Linear position transducers have a wire rope winded on a drum, whose rotation axis has on one side a spring to allow to wind back the rope and on the other side a sensor that measures the drum rotation: by knowing the drum circunference and how many turns did the drum rotate, then it is possible to precisely calculate the extracted wire rope lenght and thus the position of the object connected to the rope.
Position measurement is absolute therefore if the machine is switched off then it is not necessary to zero the actuators back to a repeatable known position.Draw wire linear position transducers DWT (also known as "wire encoders") are installed on industrial machines to measure the positions by attaching the wire rope to the mechanical part whose position is to be measured: the analog signal, proportional to the measured value, is then fed to the machine electronics (typically a PLC) in order to allow a closed loop control of the machine process.
DWT transducer can be applied in a safe position far from the application zone where only the steel rope wire reaches the position measurement is to be done where there might be application hazards like vibrations/electrical noise/chemicals/dirtyness that have negligible effect on the rope.
DWT transducer wire rope is flexible and by means of pulleys, that can be purchaed as an option, it is possible to trace a path with several turns that allow to reach positions difficult to reach by other means in order to do position measurements.
DWT transducers is versatile and cost effective because it allow to measure displacements from 1m up to 12m with a single transducer mechanical type.
Typical applications: automation machines, industrial vehicles, agriculture equipment, caterpillar type vehicles, geophisical application and tests, drilling equipment, machine tools, packaging, boats etc.
