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
with oil damping.
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.
Illumination
Internal illumination is available in the following models:
• 244 and 246 shortscale moving coil and moving iron vane.
• 243, 244 and 246 longscale moving coil and moving iron vane.
Through dial (Translucent) illumination on 244 and 246 models.
Edge illumination on 243, 244 and 246 models.
Replaceable 6, 12 or 24V lamps are used on all models except 243 longscale meters,
where the lamps are internal.
