Rotary transducers:
TWK’s electromagnetic and electro-optical rotary encoders are designed for measuring ranges from 0 to 360° and for a maximum of 32,768 revolutions. The miniature version with a housing diameter of 22 mm has a resolution of 12 bits. Multi turn encoders are availeable with diameters down to 36 mm.
Electro-optical rotary transducers
Rotary transducers and pulse generators with optical scanning offer high resolutions of up to 16 bits (65,536 steps/revolution) and are insensitive to external magnetic fields. In the single-turn range, a code disk is scanned by an LED with long-term stabilisation and an optical array. The multiturn position is recorded by an optically scanned transmission. Interfaces from analogue to field buses with safety protocol are available.
Electromagnetic rotary transducers
Rotary transducers with magnetic scanning are available in many different versions. From miniature encoders with a separate magnet hub to the heavy-duty dual-chamber systems with IP69K protection types or customer-specific embedded solutions. In addition to a rotary position, certain models can also output speed and acceleration values. They are available with various interfaces, from classic analogue outputs up to field bus interfaces with safety protocol consisting of a redundant sensor system.
Potentiometric rotary transducers
Rotary transducers with a measuring range of up to 360° are equipped with conductive plastic resistor elements. The helical potentiometers up to 10 revolutions have wire-wrapped resistor elements.
Linear transducers and gauges:
Travel, lengths, distances and shifts of between 1 mm to 7600 mm can be recorded using inductive or magnetostrictive linear transducers. Both sensor systems operate contact-free and are not subject to any wear.
Inductive linear transducers
For measuring lengths from 1 mm to 400 mm. The measuring principle enables freedom from wear, unlimited resolution, extensive reproducibility plus robust and watertight designs. High vibration and shock resistance for continuous operation.
Potentiometric linear transducers
For measuring lengths up to 1000 mm with very high precision and repeatability. Durable conductive plastic resistor path. Design with & without return spring, cable, connector and/or ball joints.
Magnetostrictive linear transducers
Magnetostrictive linear transducers enable contact- and wear-free displacement measurement with high accuracy. They offer measuring ranges between 0 – 25 mm and 0 – 7600 mm with linearity of up to 0.01%. Thanks to their completely encapsulated design, they offer protection types up to IP67. In addition to displacement measurement, the majority of models also enable speed measurement.
Displacement/angle converters:
Very long measurement displacement is converted into an angle using a mechanical facility. This angle is recorded using a multiturn rotary encoder. The measurement result is proportionate to the measurement displacement. Programmable rotary encoders can be calibrated according to the actual measurement stroke. The measurement signal may be analogue or digital.
Displacement/angle converters
Cable-type displacement/angle converters for rotary transducers
The cable-type displacement/angle converters are designed for strokes from 1 m to 60 m. The rotary movement of a cable drum with return spring is transferred to a multiturn rotary encoder. The stainless steel measurement cable is wound in a single layer onto the measurement drum and is tensioned by the return spring.
Toothed belt displacement/angle converters
In the toothed belt displacement/angle converters, a steel-reinforced toothed belt runs around a pinion. The toothed belt is tensioned with a spring element and engages without play into the teeth on the pinion. The revolutions are recorded by a multiturn rotary encoder and are converted into a measurement signal. The measurement signal is proportionate to the displacement.
Inclinometer:
For measuring two axes up to ±90° in the earth’s gravitational field. Parameters such as the measuring range and zeroing function can be programmed in the MEMS technology-based sensor.
Accessories:
Installation accessories for rotary encoders and linear transducers, programming devices and displays.
