KJT now have three production lines in factory and are preparing to install the next two new lines in the coming months. KJT engineering department has the capability to design new sensors and support existing products with technical advice and application changes.
KJT's zero speed Hall effect sensors for measurement of hub speed and shaft revolutions, etc are en¬ Gineered with an internal magnet to switch in the presence of ferrous targets such as gear teeth and blade tips down to absolute zero speed. The sensor detects fluctuations in the magnetic field and can also be configured so the output signal signifies either the presence or absence of a ferromagnetic target(i. e. A gear tooth, shaft feature, etc).
