    Thanks George, I did consider going down that road and I may even buy one as they are a very reasonable price and usefull for other things, but i wanted to encorperate it into the machine nice and neatly, which as ugly as it may be the Trexon fitted the bill. Or even something similar I could get my hands on without waiting for eternity, but it seems that this type of circuit is not available off the shelf in the UK which im gutted about.

    I have so little time in my day as it is, being a 12hr night shift worker, the only real time I can spare is sleep time, but it seems I will have to go down the Microcontroller road, as nobody on here at least can suggest any other alternative off the shelf solution to the Trexon .....:(

    Think outside the box,or in this case inside:heehee:

    Buy one, position the foil somewhere on the spindle,strip down the tachomete handheld unit,unsolder the the sensor and put/mount the digital readout in the front of the case n the boxford,solder some wires to the sensor and resolder the wires from the sensor to the digital readout unit.

    you missed two vital points George... firstly its not a sensor but a laser reflectometer which is only rated for pulsed usage and secondly, they are not continuous reading but 'read-on-demand' therefore need a push-to-read button ... as a speed readout its not that useful....

  7. Thats what I had in mind, but using a parallel interfaced display.. more common to find, cheaper to buy and easier to program.. for the added complexity of 5 more wires...

    except it cant deal with the 50:1 reduction needed...
