Hall Effect Monitor
Selected ebm blowers ordered with this
option monitor the speed of the blower with
a device consisting of a magnet and solid
state switch built into the motor. The output
signal is a low voltage DC pulse train that
can be incorporated into the end product to
trigger an audible or visual alarm or to
initiate an orderly system shutdown. This
device is suited for telecommunications,
computer, peripheral and copier applica-
tions, or others as required.
