New Big Look Taut Band - Model 250

Taut band is a means of suspending the moving mechanism between two ribbons of metal, obviating the need for pivots, jewels and control springs found in conventional mechanisms. 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. Taut band, without pivot and jewels, consequently, will withstand shock in excess of that specified for pivot and jewel meters. For example, ANSI Specifications for panel meters require 50G shock. Taut-band meters will withstand 100G shock.

New Big Look Pivot & Jewel - Model 254

Pivot & 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. Don't specify pivot and jewel meters for applications that involve high shock, but do take advantage of this meter's ability to withstand vibration.

Accuracy All DC and AC iron-vane; ±2% of full-scale AC rectifier type; ±3% of full scale (with 60 Hz sine wave at 25º C). When standard 60 Hz iron vane ammeters are used at the extreme limits of 25 or 400 Hz, additional error (approx. .75%) may be experienced. Expanded-scale voltmeters: ±.5% of full scale value.
ANSI Specification
All meters meet ANSI Specifications C-39.1
Overload Ammeters (AC and DC) momentary: 10 times the rated current for 10 consecutive intervals of 0.5 second with a 1 minute interval between successive applications; sustained: 20% for six hours
Voltmeters (AC and DC) - 50% momentary, 20% sustained
