Pressure switch Dungs LGW50A4 221592

Dungs 221592 LGW50A4 pressure switch is an adjustable differential pressure switch for combustion units. Dungs LGW50A4 221592 pressure switch is used to turn on, off or switch the electrical circuit to a set pressure value when the actual value changes. The setpoint (switching parameter) is set using an adjustment wheel with a scale. There is a measuring flange in the metal housing. Dungs 221592 LGW50A4 differential pressure switch technical data: Setting range: 2,5-50 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.
