Smiths Mechanical to Electronic Tachometer conversion -741-

Converts RN tachometers to Electronic triggering

This is a service to convert a Smiths mechanical ( cable driven) tachometer to Electronic, using carefuly chosen parts to give a period performance whilst appearing to look identical to the original mechanical tachometer from the front..

You will need to supply us with the original mechanical tachometer

We remove the needle and dial, discard the mechanical movement and replace it with a new electronic movement that uses "Air Core" technology. This type of movement offers substantial advantages over the older d'arsonaval movement fitted to the first Smiths Electronic tachometers, but the needle behaves in a very similar way to the mechanical tachometer so that it is almost impossible to tell that it is not original.

One of the advantages of this movement is that it is more than capable of operating the heavier needles found on the mechanical tachometers.

We do not paint touch-up or otherwise interfere with the patina of the original, apart from cleaning the glass.

Instructions on installation are included when we send the tachometer back to you.

Note - :   the new movement will cover the full rotation of the riginal mechanical tachometer, unlike our earlier conversions with restricted movement.

If the mechanical tachometer has a rolled on bezel, there will be a surcharge.

The conversion is negative earth

The conversion produces a clockwise tachometer unless specifically requested
