240 Series DIN Panel Meters

An extensive range of 48, 72, 96 and 144mm DIN style panel meters offering

measurement of all electrical and electronic parameters. Meters are shock resistant

and vibration proof and supplied with terminal covers. A selection of slide in dials

and customised options are available.

Movements

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

Features

with oil damping.

An extensive range of specialist

measuring meters in 4 case sizes

Dials, Scales and Pointers

Standard dials are matt white with black printed scales and bar knife-edge pointers.

Black dials with white or yellow scales and pointers are also available.

Interchangeable slide in dials are used on models 242, 243 and 244 90° moving iron,

moving coil and frequency meters.

General options include red supplementary pointers, red indexes (quadrant scales),

red, green or blue lines, bands or segments, finely spaced divisions, multi-scales,

special scales and captions to customer' requirements.
