Dungs 221590 Przełącznik ciśnieniowy LGW3A4

Dungs 221590 LGW3A4 pressure switch is an adjustable differential pressure switch for furnace units. Dungs 221590 LGW3A4 differential pressure switch turns on, off, or switches an electrical circuit based on pressure changes. The set value is adjusted with a wheel and scale. The metal housing includes a measuring flange. Used in furnace units, ventilation, and air conditioning systems to monitor air, smoke, and exhaust gases. Suitable for gases of families 1, 2, 3, and neutral gases. Dungs 221590 LGW3A4 differential pressure switch technical data: Setting range: 0,4-3 mbar Maximum operating pressure: 500 mbar (50 kPa) Measuring connection: A measuring fitting ø 9 is integrated in the metal housing Ambient temperature: -15 °C to +70 °C Ambient temperature: -15 °C to +70 °C Storage temperature: -30 °C to +80 °C Lower part of the body: Aluminum die-cast Casing: Polycarbonate Switch: Polycarbonate Membrane: NBK Switching contact: Standard: High purity silver (Ag) Degree of protection: IP 54 according to IEC 529 (EN 60529) (transparent casing) Setting: Vertical position at falling pressure. The setting of the rising or falling parameter can be performed at the installation site. In case of deviation of the mounting position, take into account the change in the switching point. Control range: 15% deviation from the switching point relative to the setpoint and installation in a vertical position Preset: Standard version: blue. Execution of “Y": yellow Dungs 221590 LGW3A4 pressure switch functional description: Dungs 221590 LGW3A4 differential pressure switch operates in the range of over and under pressure. The differential pressure acts through the diaphragm on the microswitch, counteracting the force of the mounting spring. No auxiliary energy is required for the operation of the relay. Dungs LGW3A4 221590 pressure switch approvals: Has a certificate of the European Community on passing tests of samples in accordance with EU regulations on gas equipment: CE-0085 AQ 0673 Has a European Community certificate of passing tests of samples in accordance with EU regulations on pressure equipment: CE0036 There are permits for the operation of other countries consuming gas. It has a certificate of the state technical Supervision Service for testing as a pressure switch of a special design according to TRD 604 standards and VdTÜV No. 100/1, as well as in accordance with class “S“ according to EN 1854.
