The Honeywell HST-DB is a high-accuracy differential pressure sensor designed for building automation and HVAC systems. It monitors airflow and pressure differentials (0–500 Pa) with ±2% FS accuracy, providing 0–10V or 4–20 mA outputs for integration with control systems. Its compact ABS housing and dual pressure ports make it ideal for duct pressure monitoring, filter status alerts, and room pressure control in commercial buildings.
