UHV Design has enhanced its innovative LPP (Linear PowerProbe) range of magnetically coupled linear feedthroughs with the option of motorised operation. Combining the probes' high linear thrust (up to 180N) and zero-backlash characteristics with the convenience of DC/stepper motor-driven automation results in a powerful sample delivery system for remote control applications.
UHV Design developed the LPP as a more cost-effective alternative to expensive bellows-sealed or rack and pinion style devices for manual linear transfer applications. The LPP significantly improved on other magnetically coupled feedthroughs through the incorporation of an innovative anti-rotation system, making it suitable for use in applications where potential rotation of the sample could not be tolerated. Now, with this latest enhancement, the motorised Linear PowerProbe vastly reduces the cost of automated sample transfer systems, whilst delivering high thrust, rotation-free linear motion.
The motorisation support structure is designed to minimise the Linear PowerProbe's overall mass and footprint. The structure consists of three shafts equi-spaced around the probe, one of which is the motor driven leadscrew that actuates the probe. The second shaft allows proximity switches to be fitted along the stroke length for position feedback to the controller.
The motorised LPP is available with strokes up to 1219mm (48in) as standard, and can be supplied with custom shafts and safety covers if required. Along with the DC or stepper motors, UHV Design can supply associated DC controllers or programmable stepper controllers to provide a complete solution for reliable, remotely controlled, linear transfer.
