Amplified Airflow Sensors
Contains additional electronics that boost the sensor’s output signal.
AWM3000 Series
Microbridge Mass Airflow Sensors
- Compensated.
- 30 SCCM, 200 SCCM, 1000 SCCM: 0 mbar to 1.25 mbar, 0 mbar to 5.0 mbar
- Analog output.
The AWM3000 Series is amplified: therefore, it can be used to increase the gain and to introduce voltage offsets to the sensor output. The heater control circuit and the sensing bridge supply circuit are on board the package.
AWM4000 Series
Microbridge Mass Gas-Flow Sensors
- Compensated or uncompensated.
- ±25.0 SCCM, 1.0 SLPM, 6.0 SLPM.
- Analog output.
The microbridge mass airflow sensor operates on the theory of heat transfer. Mass airflow is directed across the surface of the sensing elements. Output voltage varies in proportion to the mass air or other gas flow through the inlet and outlet ports of the package. The specially designed housing precisely directs and controls the airflow across the microstructure sensing element.
AWM5000 Series
High Flow Mass Airflow Sensor
- Compensated.
- O SLPM to 20.0 SLPM.
- Analog output.
AWM5000 Series Microbridge Mass Airflow Sensors feature a Venturi type flow housing. They measure flow as high as 20 standard liters per minute (SLPM) while inducing a maximum pressure drop of 2.25″ H2O. The microbridge chip is in direct contact with the flow stream, greatly reducing error possibilities due to orifice or bypass channel clogging.
AWM7000 Series
Amplified Airflow Sensor
- Compensated.
-
200 SLPM, ±300 SLPM
- Analog output.
AWM700 Series microbridge mass airflow sensors provide in-line flow measurement with a specially designed bypass flow housing.
The sensors measure flow as high as 200 standard liters per minute (SLPM) while inducing a pressure drop of 1 inch H2O, typically.
The AWM700 has a high flow range capability in a small package.
Honeywell Zephyr™ HAF Series – High Flow
Digital Airflow Sensor
- Compensated.
-
±50 SCCM to ±750 SCCM – Analog or digital output.
-
10 SLPM to 300 SLPM – Digital output.
Honeywell Zephyr™ HAF Series sensors provide a digital interface for reading airflow over specified full-scale flow and compensated temperature ranges. The thermally isolated heater and temperature sensing elements help these sensors provide a fast response to air or gas flow.
Zephyr sensors are designed to measure mass flow of air and other non-corrosive gases.
Honeywell Zephyr™ HAF Series – Low Flow
Digital Airflow Sensor
- Compensated.
-
10 SLPM to 300 SLPM – Digital output.
Honeywell Zephyr™ HAF Series sensors provide a digital interface for reading airflow over specified full-scale flow and compensated temperature ranges. The thermally isolated heater and temperature sensing elements help these sensors provide a fast response to air or gas flow.
Zephyr sensors are designed to measure mass flow of air and other non-corrosive gases.
