BELIMO 22ADP-18QL

In modern building automation, maintaining proper air‑flow, filter condition, and zone pressure is key to energy efficiency and system reliability. The BELIMO 22ADP‑18QL addresses these needs with a robust differential‑pressure transmitter that adapts to multiple ranges and outputs. Its eight factory‑selectable measuring ranges (for example from 0…250 Pa down to –150…150 Pa) let you tailor the sensor to your exact duct or plenum monitoring requirement. belimo.com+1 The dual‑output capability (voltage or current) makes it compatible with a wide variety of building‑management systems or PLCs. The built‑in back‑lit LCD display provides local read‑out of pressure (in Pa or inch WC) for fast commissioning or maintenance checks. The housing rating (IP65 / NEMA 4X) means the unit stands up to dust‑laden or mechanically demanding environments such as mechanical rooms and HVAC plenums. bolasystems.com Compared to simpler pressure sensors with fixed ranges or limited outputs, this model offers flexibility, durability and field‑readiness. For applications like monitoring fan belts, clogged filters, room pressurization, or clean‑room zones — particularly in fire‑service systems, parking‑garage ventilation or smart‑home automation scenarios — the 22ADP‑18QL provides a future‑proof choice. It simplifies stock‑keeping, supports advanced diagnostics and helps you deliver professional‑grade installations with reliable performance.
