The TMI Series of non-contact linear position sensors from Novotechnik offers rod-style position sensors designed for integration into hydraulic and pneumatic cylinders. Implementing the Novostrictive touchless magnetostrictive measuring process, these sensors measure positions using a passive position marker that can be moved as a free-floating element.
Additionally, the temperature coefficient of the transducer is extremely low due to the measuring principle, design, and selected materials. The low temperature coefficient, combined with a mechanically durable design, enables the TMI Series to be highly resistant to shock and vibration.These sensors are easily mounted in-cylinder through one end and attached to the cylinder with either a threaded flange or a plug-in flange. The screw-plug hole is an M18 diameter hole and the plug-in flange is 48 mm. A magnetic pick-up position marker is mounted on the application’s piston rod.
TMI Series sensors are available from stock in stroke lengths of up to 4,500 mm as well as custom lengths for volume applications. The sensors operate under pressures up to 350 bar with peaks up to 530 bar. They have an unlimited mechanical life, and linearity performance up to 30 μm.
