A stainless steel wire is wound arounda wire drum which incorporates a spring. The shaft of the drum is connected to the shaft of the potentiometer.FW22 FW31 FW80Output 0 to 2000 ΩResponsespeed 400 mm/secWire tension 7 N (ave.) 4.5 kg MAX.Ambienttemperature-20 to +60°C (standard)-20 to +80°C(FW22 high-temp. specs only)?10 to +40°C ?20 to +80°CPainted color JIS7.5BG4/1.5InstallationLocation Indoors onlyFlameproof TypeExplosion-protection type :Flameproof : d2G4Certification No. : 22828Mass 2 kg 4.4 kg 8.6 kgModel length(mm)Linearity(%)Hysterisis(%)Resolution(%)Permissiblepower (W)(at 60°C)FW22270±0.5(Note) 0.2±0.091 3.3840 ±0.052 21405 ±0.031 2.5FW31270±0.50.2±0.091 3.3840 ±0.052 21405 ±0.031 2.5270 ?
