BELIMO 22ADP-18QB

In HVAC systems, maintaining correct airflow, filter pressures, fan performance and duct differential pressures is critical for energy efficiency and air quality. The BELIMO 22ADP‑18QB is purpose‑built to solve these needs by combining advanced sensing and flexible output options in one compact transmitter. With eight factory‑selectable pressure ranges (e.g., −150…250 Pa) the unit can be tailored precisely to your application. belimo.com+1 The dual signal outputs (0…5 V/0…10 V or 4…20 mA) make integration with various building‑automation systems simple—whether analog or PLC based. The built‑in LCD display provides live reading of Pa or inch‑WC (configurable), minimizing guesswork during installation or diagnostics. The auto‑zero feature handles drift from temperature or time, ensuring dependable results with less service overhead. The rugged IP65/NEMA 4X enclosure ensures protection from dust and water, making the sensor suitable even in tougher environments like AHU plenums or mechanical rooms. Compared to basic pressure switches or fixed‑range transmitters, the 22ADP‑18QB offers superior flexibility, field‑selectable range, diagnostics display and low‑maintenance calibration. For HVAC professionals seeking robust differential‑pressure monitoring for air filters, fan belts, ductwork or clean‑room cascades, this transmitter is a strong, future‑proof choice.
