Optimise VAV Efficiency
Air Flow Sensor | Optergy AFS-864Â
Measure air flow more efficiently
The Optergy AFS-864 is a high-performance differential pressure sensor. Traditionally one of the issues with airflow sensors is the ability to maintain accurate airflow at lower flow rates. You can get unmatched accuracy with the added confidence from an industry leading accuracy.
The Optergy AFS-864 is a more accurate airflow sensor with integrated temperature compensation to measure the airflow in VAV applications. This means VAVs will perform more effectively and provide the following benefits to the end user.
Polarity-free connections on the Optergy AFS-864Â means reduced installation related errors and call-backs for system integrators or installers.
- ±4% of reading > 12.5 Pa (0.05 in. W.C.)
- ±1.5% when calibrated via air balancing - as compared to 5% of full scale for most other manufacturers
- Pressure range of up to ±500 Pa (±2 inch H2O / ±5 mbar)
- Accurate and stable (even below 1 Pa or .004’’ w.c.)
- No offset, zero drift and hysteresis free
- Calibrated and temperature compensated (-20°C to + 55°C, -4°F to + 131°F)
Better Control
Less Temperature Variation
Less Energy Consumption
The Optergy AFS-864 is a field replaceable unit. This means that if the sensor is damaged, the entire controller does not need to be replaced. Simply remove the damaged AFS-864 module from the main Optergy P864 controller and replace it. This saves both time and money while reducing waste.
While the Optergy AFS-864 is often used in VAV applications it can also be used for:
- Airflow measurement in Air Handling Units or Fan Coils
- Positioned across a filter to monitor filter loading and signal when a filter needs to be replaced
- Anywhere that airflow measurement is required.
