Honeywell announces it has expanded its Zephyr airflow sensor HAF Series portfolio with digital versions that provide airflow ranges of 0 to 20 SLPM (Standard Liters per Minute) and 0 to 200 SLPM.
- Leverages original Zephyr building block airflow sensor via bypass to main flow channel of sensor, eliminating need for a customer-designed bypass in equipment such as ventilators
- Enables choice between creating a separate bypass or using one included in the sensor
- Configurable and customizable with multiple interface and package options, a variety of flow ranges and custom calibration
- Includes a narrow Total Error Band of ±4% reading and a high accuracy of ±3.5% reading, allowing for very precise airflow measurement
- Ease of integration provided by simple electrical interfaces (regulated, compensated, calibrated, linearized) and multiple mechanical configurations (manifold mount, male and female fittings)
- Features custom calibration, including forward flow direction
- Optimized custom calibration for many gases (dry air, helium, argon, nitrogen, nitrous oxide, carbon dioxide) eliminates need to implement gas correction factors
- Bypass serves as a small parallel airflow pathway to the main airflow channel in the equipment
- Sensitivity provides a measurement that allows the customer to determine the airflow through the main flow channel
