The Siemens QBM2030-1U differential pressure sensor is designed for measuring differential pressure, overpressure and vacuum in air and non-corrosive gases in standard AHU and HVAC applications. It features a linear pressure characteristic and an analogue 0...10 V output, making it suitable for connection to building management systems and process control applications. The sensor is used, for example, for airflow monitoring, filter contamination monitoring, or fan control in ventilation ducts. Its advantages include a selectable measuring range, zero-point adjustment, a temperature-compensated measuring signal, and simple installation. The delivery also includes a connection kit with PVC tubing, duct pressure probes for HVAC ductwork, and mounting material.
