Product Detail

Gas Pressure Switch PS-LA12

The Gas Pressure Switch PS-LA12 offers the integrated precision snap action electrical
switch, as the newest generation pressure switches to provide high reliability and
long life operation. The Gas Pressure Switch PS-LA12 is designed as compact body,
which specially meets the current small size appliances. The A20 Series is designed
specifically to yield narrow pressure differentials (the difference between ON and OFF
set points) as well as to hold tight set point tolerances throughout a wide temperature range.

Typical applications include detecting blockage in gas combustion system appliances
(furnaces, fireplaces, commercial cooking appliances, water heaters, boilers, process
dryers, etc.); detecting condensate drain blockage and fluid build up; draft inducer
verification; proving fan operation; proving a blocked filter with change in differential
pressure; monitoring static pressure; sensing increase/decrease in system pressure;
proving air across heating elements; detecting ice build up in cooling coils; managing
air in VAV systems; detecting web breaks on printing, coating or other web processes.
