Product Detail

Gas Pressure Switch PS-LA13

The Gas Pressure Switch PS-LA13 offers the same proven compression spring and
precision snap action electrical switch as the other popular and widely used pressure switches.
The Gas Pressure Switch PS-LA13 is designed as compact body, which specially meets
the current small size appliances.
The Gas Pressure Switch PS-LA13 is designed specifically to yield narrow pressure
differentials (the difference between ON and OFF set points) as well as tohold 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 buildup in cooling coils; managing
air in VAV systems; detecting web breaks on printing, coating or other web processes.

*Set point range from 25Pa (0.10 wc) to 1250Pa (5.0” wc)
*Pressure differentials offer three types of 15 Pa, 25 Pa, and 35 Pa for selection (other
pressure differential on customers’ demands).
*Integrated sampling line connectors for 1/4” inside diameter (ID) tubing.
*Sampling line connectors can be positioned by 45 degrees increments.
*Integrated screw bosses for mounting.
*Separated precision snap action switch is the electrical switching element.
*Integrated bleed holes.
2. Optional Features
* Bar-code labeling on customers’ demands.
* Multiple types mounting brackets for customers’ selection.
*Sampling line connectors can be positioned on flat surface or the standard perimeter locations.
*Gold contacts for low electrical loads.
