Interruptor de presión de aire Kromschroeder DL 3AG-9K2 (84444452)

Pressure switch sensor Kromschroder DL 3AG-9K2 (84444452) — a high-quality industrial switching sensor for monitoring positive, negative and differential pressure of air, flue gases and other non-aggressive gases in engineering and process systems. This element ensures stable operation of ventilation, air conditioning, smoke extraction and automation systems due to precise actuation at a preset pressure. Key advantages ✔️ Industrial quality – developed by the leading European brand Kromschroder, certified and proven for reliable use in complex engineering tasks. ✔️ Wide range of applications – suitable for ventilation systems, boiler rooms, smoke extraction, fire extinguishing systems and air control automation. ✔️ Precise pressure control – adjustable set point allows the device to be adapted to specific pressure control tasks in the low differential range (approx. 0.2–3 mbar*), making it ideal for fine adjustment tasks. ✔️ Easy adjustment – pressure adjustment is done manually using a wheel or fixed with a screw, without additional equipment. ✔️ Reliable contacts and connection – microswitch with high contact reliability, options with visual indication (LED) depending on the model version (e.g. K2 with indicator). ✔️ Simple integration – standard electrical terminals or AMP connectors and pipe connections ensure ease of installation and compatibility with existing equipment. Where it is used Air pressure control in ventilation and air conditioning systems Differential pressure monitoring of filters and fans Smoke extraction systems and fire protection installations Automation of industrial and commercial processes
