Belimo Differential Pressure Sensor up to 2500 Pa - 22ADP-184

The Belimo differential pressure sensor is a precise sensor specially designed for monitoring air and other non-combustible gases in HVAC systems. The sensor combines high measurement accuracy with a very robust construction. Thanks to the IP65 enclosure, the device is completely dust-tight and water jet resistant, ensuring reliable operation even under harsh conditions. This makes the differential pressure sensor the ideal choice for checking air filters, monitoring fans, or accurately controlling the pressure in smoke-free escape routes. The sensor is highly versatile thanks to eight selectable measuring ranges and various output signals.

Advantages and Features

Piezo measurement technology: Equipped with a high-quality sensor element that reliably detects even the smallest pressure differences.
Universal output signals: Supports both 0...5/10 V and 4...20 mA, guaranteeing seamless integration with any Building Management System (BMS).
IP65 protection class: The robust, UV-resistant enclosure is fully dust- and water jet-proof, ideal for installation in humid air handling units or plant rooms.
8 selectable measuring ranges: Easily select the appropriate range (between -100 and 2500 Pa) via adjustable DIP switches, making the sensor suitable for virtually any project.

Installation, Maintenance and Applications

The Belimo differential pressure sensor is designed for mounting on walls, ducts, or directly inside air handling units. For correct operation when measuring differential pressure, the supplied hose sets are connected to the sensor’s 6 mm connections. The enclosure provides a secure and clear connection through a pluggable terminal block and a cable gland with strain relief. The sensor is widely used in commercial buildings and industry for filter monitoring, fan control, and maintaining overpressure in smoke-free escape routes.
