Overview: SIKO wire-actuated distance sensors
Linear distance measurement by means of wire-actuated encoders / string pots that are available in various forms and sizes. Depending on their design, several interfaces for transfer of measured values can be chosen.
Length measurement technology with SIKO wire-actuated encoders / string pots
SIKO wire-actuated encoders / string pots have been in use for many years in the field of length measuring technology and have already proved their worth in different conditions, including difficult conditions. Sturdy compact design combined with highest precision and reliability are the governing criteria of new developments in this area.
Only a wire-actuated encoder can be used as a linear measured displacement encoder for many applications because no guided sensor systems can be used due to the spatial constellation.
Wire-actuated encoders are flexible regarding integration and interfaces
The easy assembly and guiding of the wire pull-out means that the measuring system can be integrated in existing systems simply and flexibly. Different interfaces and output signals make it possible to connect to a vast range of different control concepts.
Wire-actuated encoders / string pots are sturdy, even under adverse conditions
Because of the possibility of attaching various rotary encoders, the wire-actuated encoders / string pots offer a wide range of possibilities for use, regardless of what signal output is required. The user is able to assemble the encoder himself or herself using simple means. Outdoor use, something that can never be ruled out for mobile machines in particular, is already standard for the wire-actuated position encoders, which meet the necessary prerequisites: working temperature ranging from -40°C to +80°C, robust casing that can include outlets by means of which fluid in the device can be drained off again.
Basic design of the SIKO wire-actuated encoders
How they work could not be simpler: a measuring wire is wound onto an internal drum in one layer, guaranteeing very high linearity across the entire measurement range. When the wire is pulled out, the drum rotates. The angle sensor connected directly to the drum axis registers this rotation and produces a measurement signal that is proportional to the wire movement and that can be evaluated at will. The wire is returned using a spiral spring on the rotational axis of the drum. Because the wire is simply attached to the measurement object, the assembly effort is especially low.
Guide rollers male indirect measurement distances possible
As a result, there is no need for any additional guiding systems or for the installation of energy chains. The flexible wire also allows for linear position measurements in inaccessible locations. Indirect measurement paths can also be realized with the help of guide rollers.
Wide range of measurement distances
From compact designs in miniature format from a measurement length of 600mm to solutions with wire pull-out lengths of 15m, these wire-actuated encoders / string potscover almost the entire range of industrial use.
