Pressure switch Dungs UB500A4 210970

Dungs 210970 UB500A4 pressure switch is an adjustable device for automatic burner control. Dungs 210970 UB500A4 differential pressure switch turns on, off, or restarts the circuit when the actual pressure deviates from the set control value. The switching point is adjusted using a scale-equipped adjustment wheel. A standard measuring nozzle is integrated into the metal housing. Dungs UB500A4 210970 pressure switch technical data: Setting range: 100-500 mbar Max. operating pressure: 600 mbar (60 kPa) Ambient temperature: -15 °C to +60 °C Medium temperature: -15 °C to +60 °C Storage temperature: -30 °C to +80 °C Housing: aluminium die casting Switch: Polycarbonate Membrane: NBR Degree of protection: IP 54 as per IEC 529 (EN 60529) Setting tolerance: ± 15% switching point deviation based on the setpoint and with unit installed in a vertical position Dungs UB500A4 210970 pressure switch is used to monitor pressure in heating, ventilation, and air conditioning systems. It is suitable for gases of families 1, 2, 3, and other neutral gas media. Dungs UB500A4 210970 differential pressure switch functions as a one-way limiter within a specific pressure range and operates without an additional power source.
