| Movements: |
Taut Band |
| The absence of friction
resulting from this permits greater sensitivities
and provides more rugged meters.Common
failures of conventional meters subjected to
shock testing are cracked jewels and/or
blunted pivots. |
| Pivot and Jewel |
| In this design the coil and pointer are
supported by polished steel pivots at each
end which fit into jewel bearings. Pivot and
jewel meters are recommended for high vibration
environments because of the
mechanism’s inherent stability and strength.
Accuracy and repeatability are almost equal
to the taut-band’s, and good performance
from the pivot and jewel construction is the
reason for its long popularity. |
