Honeywell Zephyr™ Airflow Sensors offer customers unique value in six ways. The first of the advantages is a Total Error Band measurement as low as ±2.25% FSS. Total Error Band provides the sensor’s true measurement of performance over the compensated temperature range of -20°C to 70°C and is the most meaningful measurement of accuracy because it is a single specification which includes all the possible sources of error that the sensor could possibly experience. The Total Error Band should not be confused with the term accuracy as accuracy is only one component of the measurement. The Zephyr™ Airflow Sensors’ Total Error Band allows for very precise airflow measurement and is often ideal for demanding applications with high accuracy requirements. This feature is a competitive differentiator for Honeywell.
