Product Description:
space
The GL series is equipped with d’Arsonval & Taut band type movements and are available with linear scales, in different case sizes ranging from 1 1/2″ to 8 1/2″. AC Instruments are either moving iron vane type with viscous dampening or rectifier type.

Scaling: Customized to any scaling desired, from linear to specialized Cos Ø, square root distributions, with color applications for visual emphasis and to any desired engineering units.
Specific accuracies
Basic Accuracy: ±2.0% of full scale basic accuracy class.
Rectifier Type Meters: ±3% of full scale basic accuracy class.
Repeatability: ±2% for Pivot and Jewell ±0.5% for taut Band
Position of use: Vertical (scale) standard or to specified angle or position
Full scale deflection: 90 °
Movement: 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.
