Rosemount Differential Pressure Transducer
This differential pressure transducer is engineered specifically for air handling applications, including HVAC systems, airflow metering, and room pressure control. Utilizing advanced silicon-glass sensing technology, it provides high sensitivity and long-term repeatability.
Designed to be ready for installation out of the box, this unit follows a “Terminal Point” accuracy standard, meaning it meets its rated performance without the need for user calibration at the time of setup.
Key Features
Plug-and-Play Accuracy: Meets rated specifications immediately upon installation with no field adjustments required.
Diagnostic LED: Built-in indicator for troubleshooting, verifying correct wiring, and locating the unit in dark enclosures.
Simple Wiring: Euro-style pluggable terminal blocks reduce wiring errors and speed up installation.
Flexible Mounting: Compact design comes standard with DIN rail and surface mount capabilities.
Signal Options: Field-selectable voltage outputs or a dedicated 4-20 mA loop.
Reliability: Superior overpressure protection and backed by a 3-year product warranty.
Technical Specifications
Accuracy: Options for ±0.25%, ±0.4%, or ±0.8% of span (includes all errors).
Pressure Ranges: * Unidirectional: 0.10″ to 100.00″ $H_2O$.
