These meters are used for measuring the active and reactive power of AC single and three phase networks. They are primarily built in switchboards and electric devices.
|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.|
|Basic Accuracy:||±2.5% of full scale, basic accuracy class.|
|Repeatability:||±3% for Pivot and Jewell|
|Position of use:||Vertical (scale) standardor to specified angle or position|
|Full scale deflection:||90 °|
|Movement:||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.|
