Spring scales/force gauges
I need a force gauge (or two), to measure 0-300g and 0-3kg.
I can find plenty of old brass scales for collectors, luggage scales for weighing up to 100kg of one's excess airline baggage, and very costly precision instruments for measuring the tiniest forces, but nothing corresponding to the ranges I need to measure. Do these things have another name that I could look for them under? They need to be reasonably accurate - within 10g at the bottom of the range. The pictures in the service manual I'm using show a spring gauge, so I presume that such things of suitable accuracy must be available. Daniele |

I bought a 30Kg digital one for checking the contents of caravan gas bottles and it gives 0.1Kg, of the type fishermen use - it only cost about £3-50 delivered. They do other ranges too, even gold jewelry weighing scales. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

But it might help to know what the actual application is. -- *Funny, I don't remember being absent minded. Dave Plowman London SW To e-mail, change noise into sound. |

But it might help to know what the actual application is. It's to measure (and help set) the torque or pressure of various parts of a tape recorder - the spool motors, pinch wheel, and so on. The manual calls for one measuring up to 300g and one up to 3kg. I think this looks as though it might be OK: http://www.scalesexpress.com/product.php?productid=16552 even if its graduation is only 25g. Daniele |
