The NIR-9 level switch is suitable for a wide variety of applications
for bulk material and solids in silos and hoppers. Product level
is reliably controlled, regardless of humidity and conductivity
of the product. Different vanes and process connections are
available, according to product and tank size. During operation,
a motor drives a rotating vane on an extended shaft. As soon as
the media reaches the rotating vane, its rotation is impeded. The
restoring force moves the pivoted motor away from its original
position. A micro-switch is actuated, which gives out an alarm
signal. A second microswitch turns off the motor. If the filling
level decreases, the rotating vane is released again and the
force of a spring pulls the motor back to its original position. The
motor restarts and the working contact is switched back. The
switching sensitivity can be adjusted to three different settings
by changing the spring position.
