Bestech Australia has introduced the eddyNCDT 3001 and 3005 current sensors that measure displacement, distance, position, oscillations and vibrations at high speeds of up to 100kHz. They provide high precision non-contact measurements while staying wear-free in harsh environments.
Due to their compact design, the 3001-model sensors are increasingly used in applications that have to date only been reserved for inductive proximity sensors, according to the company. They are particularly well-suited to the detection of high speed processes, operating with a frequency response up to five times higher than inductive sensors and are therefore able to reliably detect fast movements at up to 5kHz. Elaborate linearisation procedures during production enable a linearity of 28µm.
The 3005-model sensors consist of sensor, cable and external miniature controller. The sensors can be custom engineered for high temperature applications to up to 180°C. Due to their pressure-resistant, thermally stable and compact design, the sensors are suitable for machine integration. Controller, cable and sensor are pressure-resistant up to 10 bar. The company has stated that compact, robust sensor designs and high measurement accuracy, combined with a favourable price/performance ratio, make these sensors suitable for high volume applications and for integration into plant, equipment and machinery.
