Comments:
*FSL AAA BB CC DD EE X indicates
switch models where:
“AAA” represents the switch assembly nominal length in
inches;
“BB” represents the nominal wire harness length in feet;
“CC” represents the housing material;
“DD” represents the float material;
“EE” represents the mounting threads (if applicable);
“X” where a “C” in this position indicates that the assembly
is designed to be suspended by its cable,
otherwise this character
will be “0”.
The FSL series switches alone were evaluated at the bottom of the test chamber.
The evaluator states that the switch mechanism can be suspended from the top of
a tank or other location where a high level alarm is needed. Depth of the liquid
will therefore differ from levels reported.
The evaluator reports that the FSL series switches meet the requirements for
level sensors installed in tanks, sumps, interstitial spaces or other
configurations where the presence of liquid needs to be indicated.
The FSL series switches are connected to the switch monitor. An alarm signal is
transmitted by radio frequency (RF) to the alarm console where the condition of
the sensor is indicated.
The evaluator reports that alarm information from the switch monitor can also be
received by a Centeron TC series controller which can relay sensor condition by
phone line to the Centeron Data Collector for remote data access over the
Internet. Transmission of the RF signal to the controller was not evaluated.
