Continuous
Level Transducer
Madison's
continuous level transducers are designed for
vertical mounting in a tank. Reed switches
are evenly spaced over the operation range
to achieve the desired resolution. A single
magnet-containing float travels the length
of the sensing range. The reed switches are
magnetically actuated as the float moves with
the liquid level. DC power is applied to the
switch, and the output signal can then be routed
to programmable controllers, microprocessors
or other readout devices.
Model
C3946 is a 10mm resolution continuous level
float switch with a stainless steel or brass
stem and available with either a polypropylene,
Buna-N or stainless steel float.
Model
C3957 is a 5mm resolution continuous level
float switch with a stainless steel or brass
stem and is available with either a stainless
steel, polypropylene or Buna-N float.
Both
models are suitable for petroleum-based liquid
applications, in addition to many other liquids
with low- to mid-range viscosity.
