Product Description：
Many large machines requiring differential expansion monitoring do not have a
convenient location for mounting the large proximity probes required to make
this important measurement. Extremely large machines may require a
monitoring range beyond the linear range of even the largest available
transducers. The 3300/46 Ramp Differential Expansion Monitor provides for an
alternate measurement technique that allows increased monitoring ranges from
standard transducers. It is also extremely useful when conventional methods
from a collar are not possible.
Two proximity probes are used to observe ramp surfaces, on the rotor, in order
to provide one channel of differential expansion. Using ramp surfaces allows
increased monitor range with smaller transducers.
The monitor's ability to use
ramp surface targets also provides added flexibility when choosing a transducer
mounting location.
Both the magnitude and direction of differential expansion are displayed on the
LCD. The monitor provides four alarm setpoints (two over and two under alarms).
