Selection Guide: |
| The
first consideration is the type of liquid,
temperature and pressure to which the switch
will be subjected. Madison manufactures liquid
level switches
in various styles, in a variety of materials,
to cover a broad range of conditions. Following
are some basic recommendations for selecting the
proper liquid level switch material for your
application. |

|
| Material |
Application |
| 316
Stainless Steel |
For
high-temperature (to 300°C), high-pressure
(to 300 PSIG) and corrosive conditions.
Commonly used in food processing, medical,
heating
and cooling equipment.
|
Polypropylene
Polysulfone |
For
acidic conditions, such as found in electroplating
and metal cleaning. Another choice for lower-temperature
(to 105°C) food processing applications
(Madison Company uses only polypropylene
that is FDA-approved for food contact). Also
a good choice for general-purpose applications
in commercial or consumer appliances and
equipment. Available in white and other colors. |
Brass & Buna-N
PBT & Buna-N |
The
selection for petroleum-based liquids, such
as lubricating oils, gasoline and diesel
fuels. Widely used in storage tanks of vehicles,
generators, transmissions and hydraulic systems.
Other uses are in lubrication, recovery,
refining and fuel processing equipment.
Please note: PBT is not suitable
for use in temperatures above 130°C. |
Kynar
PTFE
|
Chemical-
and solvent-resistant properties make this
material a problem solver for many applications.
Its high-purity nature is ideal for food
handling and sensitive laboratory or test
equipment. |
|
| Once
a suitable material has been selected, the type
of switch and configuration are the next considerations.
Madison Company stocks a full line of standard
products that can meet the requirements of many
applications. For specific designs, Madison can
custom build, to order, switches with an infinite
number of variations and options. Please utilize
our multi-point specification
sheet which, when completed,
will allow our engineering department to better
meet your needs. |
