About this product
Siemens QBM2030-5 is a differential pressure sensor used to measure low pressure differences in HVAC applications, such as room pressure monitoring, filter condition monitoring (pressure drop across filters), and airflow verification in ducts. It supports selectable measuring ranges (e.g., 0–200 / 0–250 / 0–500 Pa, depending on configuration) and provides a 0–10 V output that can be read by an HVAC controller or Building Management System (BMS). It typically operates on 24 VAC or 13.5–33 VDC and is wall-mounted, with pressure tubes connected to the required measurement points. This sensor helps maintain proper ventilation control and required pressure differentials in sensitive areas (e.g., equipment rooms or zones requiring positive/negative pressure
