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.
2. Technical Parameter:
A) PS-LA1:| Model | PS-LA1 | | Media | Air, natural gas | | Operating Pressure Range | 0.15" W.C. to 34" W.C. | | Proof Pressure | 100" W.C. (3.6 PSI) | | Operating Temperature | -40 °C ~ 85 °C (-40 °F~185 °
F) | | Contact Arrangement | SPST or SPDT | | Electric Rating | Resistance: Initial: <50 milliohms
Current: 100mA minimum, 5A resistive maximum
(fine silver alloy contacts);
15mA minimum, 0.5A resistive maximum
(gold-platinum-silver alloy contacts); | | Terminals | 6.3 mm (0.25") copper alloy | | Connection | Inlet 0.25" for tube connection | | Agency Approval | UL, CE |
|
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. |
| Switch Differential | Not less than 0.1mb and not greater than 0.3mb depending on pressure settings. |
| Maximum Operating Pressure | 10mbar Pmax=50mbar. |
| Operating Temperature Range | 105°C Maximum |
| Electric Rating | 125V,250V, 5A single pole on-off or single pole change over. Other ratings are available on request. |
| Contact Arrangement | SPDT or SPST |
| Terminals | 6.3 or 4.88 mm male Q.C. Optional insulation cover available as necessary. |
| Calibration |
LFAS switches are normally calibrated at their lower switching pressure in accordance with customer requirements.
Ramp rate at switch point=0.03mb/second |
Calibration Tolerance | Standard production tolerance at ambient temperature is ± 0.10mb or ± 5% of set point, whichever is the greater. |
| Pressure Connections | 6mm O.D. push on or "Permifix" tubing. The lower (negative) connector may be supplied in any one of four positions for ease of installation. |
