Description
| For industrial or commercial applications,
the Round style, single phase wattmeter offers maximum reliability
and ±2% of full scale (F.S.) accuracy (±3% F.S. for
Compensated type). With a black phenolic case and glass window for
optimum viewing, the Round style meter is a popular replacement.
Two popular sizes of 2-1/2" and 3-1/2" (3-1/2" size
only for Compensated type) are available to measure from 20 watts
to 3000 watts. Due to power dissipation, errors are usually prevalent
in standard wattmeters at low values of power. This error is corrected
in Simpson’s Compensated Wattmeters. The Simpson dynamometer
movement is calibrated for either magnetic or non-magnetic panels
and for a frequency range of 25-125 Hz. The dynamometer movement
is air-damped, utilizing the same high quality pivots and jewels
as the other fine Simpson meters to support the moving element.
This style of meter is ideal for many other electrical functions. |
