Product Description

Product Description

 

Natural Gas Pressure Switch

1. Introduction:

PS-LA1 switch is designed for using in the Heating, Ventilation, Air-conditioning (HVAC) industry, where safety and reliability are essential. This model switch has been proved to be a viable solution for gas-fired warmer, hot air furnace, water heater and other heating appliances.  
 
PS-LA2 adopts a differential pressure to actuate a precision snap switch at chosen pressure setting. This may be the difference between atmospheric and a negative or positive pressure or between any two given pressures. When a change of pressure occurs between the negative pressure chamber and the positive pressure chamber the main diaphragm activates the snap switch at a pre-determined value.

Conversion:  1"W.C. = 1 inch/H2O=249Pa   1mbar=100Pa 

B) PS-LA2:
 

Media	Air , products of combustion, L.P. or natural gas
Mounting /Fixing	4 screws with maximum penetration depth of 6.3mm into appropriate mounting holes, or fixed with optional bracket.
Mounting Position	The LFAS is position sensitive. It may be mounted in most positions provided it has been calibrated.
Field Adjustable Range	0.4mbar to 8.0mbar make on positive or negative pressure rise. Minimum upper switching pressure 0.4mbar. Minimum lower switching pressure 0.2mbar.
