In Crompton Instruments’ world-patented

‘Hi-Q’ taut band suspension, all the delicate

parts of the traditional instruments are

eliminated. There are no pivots, no jewel

bearings, no hair-springs and no air damping

vane. Instead, a tough platinum ribbon

suspends the moving element between front

and rear tension springs.

Specially contoured pads are fitted to the

ends of the spindle, and the working gap at

each end is filled with a high quality silicon

fluid. The pads, together with the fluid

reservoir, form a system which acts as a

resilient built-in shock absorber. This

provides both rotational and longitudinal

damping as the moving element floats on oil

with no bearing friction and is effectively

cushioned against shock and vibration.

360° Synchroscopes and power factor

meters have robust pivot and jewel bearings

with oil damping.
