Press Release/FZ-i series0 pages
A&D Company, Limited, a leading manufacturer of laboratory and industrial electronic balances, has recently released the FZ-i Series precision balances (120 ~ 300g 1mg, 1200 ~ 3000g ח 10mg). Naoto Izumo, chief engineer in A&Ds research & development division, explains two principal technologies incorporated in the FZ-i Series. Background Social and industrial infrastructures rest upon products supported by technology Particularly, weighing products are used in many fields and therefore occupy a role akin to a mother machine for industrials. In this regard, A&D believes that manufacturers of weighing products assume great responsibility. For many years, A&D has made an effort to provide high-performance weighing products at reasonable prices in order to promote technology upgrades in as many fields as possible. The FZ-i Series is a result of these efforts. Two technological innovations characterize the FZ-i Series; the Compact Super Hybrid Sensor (C-SHS) and the air-pump controlled, direct-acting internal calibration unit. C-SHS Most electronic precision balances adopt an electro-magnetic compensation method for their weighing sensors. This method equilibrates the Lorentz (electro-magnetic) force generated by the electro-magnetic unit at one end of a beam with the weight of the object placed at the other end. The electro-magnetic unit consists of a force coil and a magnetic circuit, which requires an expensive rare-earth magnet to generate the Lorentz force. In order to achieve more competitive pricing for the FZ-i Series, A&D focused on reducing the size (and consequently the cost) of this magnet for the magnetic circuit. >
