Twiist technology
The heart of TWIIST technology is a Hall-effect 3D sensor, mounted on an electronic board and coupled to a magnetic field generated by a helical magnet. This design allows the sensor to move freely within the magnet in a linear fashion.
By measuring the variation of the angle of the magnetic field vector along the cylindrical case, it is possible to determine the precise position of the Hall-effect integrated circuit and then accurately measure the displacement. This approach allows for a greater scalability of sensor length compared to traditional multi-chip Hall-effect implementations.
TWIIST technology is patented, ensuring unparalleled exclusivity and innovation in the industry.
Twiist position sensors
The LS-A, LM-L and LM-C sensors offer exceptional versatility thanks to their analogue and digital outputs, which include FULL-Redundant, IO-Link and CANopen. This adaptability makes them ideal to meet the requirements of Industry 4.0 and for use on mobile vehicles.
The high-performance digital transmission of process variables, such as position, angular velocity and acceleration, ensures accurate data acquisition and rapid response to changes in position. This makes the TWIIST series transducers particularly effective in contexts that require precision and responsiveness, providing reliable and timely results. The sensors are available with strokes (FS) ranging from 50 to 900 mm, offer a typical linearity of 0.15% FS and a position repeatability of 0.05% FS.
These sensors are designed to withstand extreme temperature conditions, operating effectively in a range of -40 to +85°C. This ensures their integrity and functionality even in extreme conditions, while maintaining reliable and consistent performance. In addition, they offer numerous mechanical connection options, including self-aligning joints for maximum ease of installation, facilitating integration into different applications.
Self-correction
Thanks to the presence of fixing joints, any mechanical misalignment during the installation or movement of the parts is automatically corrected. This ensures accurate and repeatable measurements, improving the reliability and accuracy of the measured values.
Predictive maintenance
TWIIST technology allows you to reconstruct a three-dimensional trajectory of the end-effector of the machine being monitored, using raw data such as tilting angle, acceleration and speed. This information, combined with the data retrievable from the IO-Link and CANopen variants, allows you to implement a thorough control of the machines where they are installed.
In addition, the embedded computing capacity of the sensor offers useful information for subsequent edge or cloud processing, adapting to different automation needs.
Waterproofing
TWIIST technology, based on the Hall effect, is by definition non-contact, which makes it immune to wear on mechanical parts. The electronics are enclosed in an aluminium profile, impermeable to dust and surrounding liquids. This ensures greater durability and reliability of the sensor even in harsh environments.
Easy to update
Upgrading the firmware via bootloader in IO-Link and CANopen versions allows for quick and easy updating directly in the field. This feature ensures that the TWIIST sensor is always up-to-date with the latest fixes and improvements available.
