BE39 Bimetallic ammeters

Maximum ammeters – BA and BE series are designed 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.

 

Description

Lumel BE39 Bimetallic ammeters – Maximum ammeters – BA and BE series are designed 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.

The BE39 Bimetallic ammeters responds and indicates the mean rms current loading over a specified period of time. A black pointer which is attached to the bimetal spiral. A red pointer (slave or memory pointer) is driven by the black pointer. The red pointer remains at its maximum position to which the black pointer has reached during any period of time.Furthermore, when the loading is reduced the red pointer remains at the maximum value.
