Bimetallic ammeters
BA27, BA39, BE27, BE39
Maximum ammeters - BA and BE series are destined to measure the averaging RMS value of a a.c. current, in a 8 or 15 minutes’ period.
An additional red pointer, displaced by the black pointer, shows the maximal current value which occurred from the last zeroing of the meter indication.
The applied bimetal movement is especially useful when measuring the load in power line, of generators, electrical motors and others, where important momentary changes of load occur.
