Przełącznik ciśnieniowy Dungs LGW1, 5A2-7 2574347

Dungs LGW1,5A2-7 257434 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 LGW1,5A2-7 257434 pressure switch technical data: Setting range: 20-150 Pa Max. operating pressure: 100 mbar (10 kPa) Pressure connection: hose gland ø 4.6 mm Ambient temperature: -15 °C bis +85 °C Medium temperature: -15 °C bis +85 °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 257434 LGW1,5A2-7 differential pressure switch application: Dungs LGW1,5A2-7 257434 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 257434 LGW1,5A2-7 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 LGW1,5A2-7 257434 differential pressure switch functional description: Dungs 257434 LGW1,5A2-7 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.
