This stand is composed of the following elements: a static frequency converter that supplies a three-phase asynchronous motor, a tachymeter for rpm measurement a central unit and monitor for control and monitoring, and a single-phase synchronous generator for loading the three-phase asynchronous motor.
V. Ryan Â© 2004 2009. The depth gauge micrometer is a precision measuring instrument, used by engineers to measure depths. Each revolution of the rachet moves the spindle face 0.5mm towards the bottom of the blind hole. The diagram below shows how the depth gauge is used. The ratchet is turned clockwise until the spindle face touches the bottom of the blind hole. The scales are read in exactly the same way as the scales of a normal micrometer (see previous information sheets).
