Type BFA Series
These variable rheostats are produced
using constantan (CuNi44) wire,
wound onto ceramic formers, with
insulated wire to give mechanical
stability and good heat dissipation.
A leaf spring type wiper, with a
ceramic handle is used to vary the
resistance.
The resistors are protected with a
perforated, pressed steel cover and
three laboratory terminals are provided
so that the unit can be used as a series
resistor or potential divider.
These are ideal to provide variable
current outputs in all laboratory
environments.
