Kromschroder DG150U-3N (84447513) Gasdruckschalter
Gas pressure switch Kromschroder DG150U‑3N (84447513) — a high-precision industrial pressure sensor-switch from the renowned German manufacturer Kromschroder, providing reliable control of the working medium in gas and air equipment systems. This device is a key element of automation, responsible for the safety and stability of operation of burners, boilers, ventilation units, and other gas systems. Main purpose and functions This pressure switch is designed for monitoring and regulating gas and air pressure, as well as controlling the pressure difference between two points in the system. The device records pressure values and closes or opens electrical contacts when a set threshold is reached. Such control is especially important for preventing emergency situations — for example, when pressure drops below a safe level or when it rises excessively. ⚙️ Technical capabilities and advantages: • Adjustment range: from 30 to 150 mbar — optimal range for typical industrial, boiler, and ventilation systems. • Versatility of control: the device works with positive gas/air pressure, negative pressure (vacuum), and differential pressure. • Manual adjustment: a wheel on the housing allows setting the response threshold — you can easily configure the pressure switch to your system conditions. • Contact switching function: when the set pressure is reached, the pressure switch can close, open, or switch contacts, providing flexibility in control logic. • Reliable design: IP 54 protection rating ensures resistance to dust and splashes, and the housing made of durable materials ensures longevity. • Compact and easy installation: thanks to standard screw terminals and M16 cable entry, installation and integration into the system are quick
