Meter – Dual Sensitivity Micrometer

Each centre hole coil is wound on a plastic former & is provided with 4 mm socketed terminals.

The coil fits onto a double ‘C’ core, provides a suitable transformer for operation from a low voltage AC supply. In addition, it provides a useful electromagnet if used on one half of a ‘C’ core.

This model uses the same basic assembly as the electric motor, mounted on a base plate which also carries a hand drive pulley 120 mm in diameter coupled to the smaller dynamo pulley by a rubber belt. Electric output is via a pair of 4 mm socket & a light emitting diode is provided as simple output indicator. The model may also be used as motor on a 4 to 8 volts DC supply.
