Sensors for Distance & Position
Draw Wire Sensors
Draw wire sensors are low-cost, compact sensors which accurately measure the position or change in position of objects. Core components of a draw wire sensor are a precision measuring wire and a sensor element (e.g. potentiometer or encoder), which convert the path change into a proportional electrical signal. The maintenance-free draw wires are particularly quick and easy to assemble and are used because of their reliability in all areas of industry.
Digtial Length Gauges
Digital length gauges from HEIDENHAIN are high-precision sensors and offer accuracy over the entire measuring range. They feature consistently high accuracy over a long period of time as well as high thermal stability. Whether the part measures 10 mm or 100 mm, its actual dimension is always measured with the same high quality. HEIDENHAIN length gauges are built for a great variety of applications and are used in an industrial environment. They have a wide range of applications in production metrology, in multipoint inspection stations, measuring equipment monitoring, and as position measuring devices.
Digtial Linear Scales
Digital linear scales use a sensing head, that runs along a moulding. They operate with a non-contact magnetic measurement system. The scale should be mounted to a levelled surface, to ensure a high precision measurement.
Linear potentiometers are an inexpensive and reliable way to measure distances or positions. These resistive sensors work as a voltage divider via a hybrid layer of plastic and are available up to a protection class of IP68. Linear potentiometers combine simple design with high precision (linearity up to 0.05% of the FS). A wide variety of designs and mounting options enable use in countless applications.
