DSP400
Brief Description:
The Honeywell DSP400 is a high-performance differential pressure sensor designed for HVAC systems, cleanroom monitoring, and airflow control. It provides high accuracy (±1% FS) and fast response (<5 ms), making it ideal for energy-efficient ventilation, filter monitoring, and static pressure measurement.
With both analog and digital output options, it integrates easily into building automation (BAS) and IoT systems. Its compact, rugged design ensures reliability in harsh environments, while IP65 protection resists dust and moisture ingress.
