    摘要: An electromagnetic force transducer 1 balances the load placed on the weighing tray 7. To prevent errors due to ambient temperature variation the transducer 1 is enclosed by a casing 2 which is kept at a constant temperature, above ambient, by heater unit 3 and temperature sensor 4 connected through electronic circuit unit 10. A hook 5 which transmits the balancing force to the pan 7 passes through an opening 6 in the bottom of the casing 2 which can be fitted with a sleeve to minimize convection. Heat generated by the electronic control circuits can be used to maintain the temperature of the enclosure 2.
