Pressostat d'air Kromschroeder DL 5K-3W (84444700)

Air pressure switch sensor Kromschroder DL 5K‑3W, art. 84444700 — professional industrial pressure sensor from German brand Kromschroder, designed for precise control of air and non-combustible gas pressure in ventilation, air conditioning, heating and air exchange systems. This device ensures equipment stability and operational safety of technical systems. What it is and why it is needed The DL 5K‑3W sensor monitors positive, negative and differential air pressure, reacting to deviations from set value and automatically closing/opening electrical contacts when set level is reached. This prevents incorrect equipment operation, malfunctions of fans, filters, blowers and smoke extraction systems. ⚙️ Key advantages ✔ Reliable operation over wide range: device is designed for precise control of low pressures in range 0.4–5 mbar, making it ideal for most air systems. ✔ Manual adjustment: built-in hand wheel allows easy set point adjustment for specific operating conditions without special tools. ✔ Simple connection: electrical connection via convenient screw terminals facilitates installation and maintenance. ✔ Compact and robust design: device has reliable housing and low weight, suitable for dense arrangement in technical cabinets. ✔ Origin — Germany: original Kromschroder ensures high quality, durability and compliance with European standards. Increased safety: timely sensor activation prevents emergency situations related to incorrect air pressure. Stable operation: device reliably adjusts and provides stable control even in
