Pressure switch Dungs LGW150A2P 120238

Dungs LGW150A2P 120238 differential pressure switches are adjustable differential pressure switches as per EN 1854 for automatic burner controls. Suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value. The reference value (switching point) is adjusted on a setting wheel provided with a scale. Dungs LGW150A2P 120238 pressure switch technical data: Setting range: 30-150 mbar Max. operating pressure: 500 mbar (50 kPa) Pressure connection: G 1/4 tapered female thread for higher pressure on centre of housing underside, including test button and on the side 4.6 dia. test point; G 1/8 female thread for lower pressure. Ambient temperature: -15 °C bis +70 °C Medium temperature: -15 °C bis +70 °C Storage temperature: 30 °C bis +85 °C Housing: Polycarbonat Switch: Polycarbonat Diaphragms: NBR Degree of protection: IP 54 IEC 529 (EN 60529), protection insulated, optional IP 65 Setting tolerance:  ± 15 % switching point deviation, relative to nominal value, with vertical mounting position. Rising (↑) or falling (↓) setting available on site. Dungs 120238 LGW150A2P differential pressure switch application: Dungs LGW150A2P 120238 pressure monitoring in firing, ventilation and air-conditioning systems. Suitable for air, flue and exhaust gases and other non-aggressive gases as differential pressure switches; not suitable for industrial combustion gases. Dungs 120238 LGW150A2P pressure switch approvals: EC type test approval as per EC Gas Appliance Directive: CE-0085 AQ 0673 EC type test approval as per EC Pressure Equipment Directive: CE0036 Dungs LGW150A2P 120238 differential pressure switch functional description: Dungs 120238 LGW150A2P differential pressure switch in pressure and vacuum range. The differential pressure acts via the diaphragm against the force of the setting spring on the microswitch. The pressure switch operates without auxiliary power.
