Honeywell Amplified Airflow Sensor , AWM5000 Series, Dry Gas, 0 - 5 L/min, 15V DC, 50 psi Max

Honeywell’s AWM5101VN is an amplified airflow sensor from the AWM5000 Series, engineered for precise dry gas measurement within a flow range of 0 to 5 L/min. This device incorporates microbridge sensor technology, utilizing a heater resistor flanked by two temperature-detecting resistors. The venturi design accurately gauges gas flow by measuring differential pressure at two points, supporting high reliability and minimizing the risk of sensor clogging. Its amplified signal conditioning optimizes performance and facilitates easy integration into applications requiring dependable flow measurement.

The rugged plastic housing of the AWM5101VN is capable of withstanding common mode pressures up to 50 psi, making the sensor suitable for industrial and laboratory deployments. Installation is simplified by the male 1/4 inch NPT connection, providing secure and versatile compatibility with standard pipe fittings. Active laser trimming assures sensor-to-sensor interchangeability, enhancing calibration and operational consistency across deployments. The linear voltage output and remote mounting capability expand integration possibilities for automation and control systems.

Operating effectively within a temperature range from -20°C to +70°C, this sensor is intended for environments that demand robust thermal stability. The device receives up to 15V DC supply voltage, accommodating standard control equipment interfaces. With RoHS compliance, the AWM5101VN meets industry requirements for environmentally responsible manufacturing and regulatory standards. The maximum media temperature of 50°C further supports operational flexibility in varied conditions.

Typical applications include gas chromatography, electronic fuel injection systems, medical respirators and ventilators, leak testing, and HVAC monitoring. The microbridge chip’s direct contact with the flow stream reduces susceptibility to errors stemming from orifice or bypass channel clogging, ensuring more accurate and durable flow sensing. Separate calibration types are supported for argon, nitrogen, or carbon dioxide gases, facilitating diverse laboratory and industrial use cases.

Installation is enhanced by a connector compatible with AMP standards, delivering reliable connectivity in demanding environments. The small sensing element can withstand mechanical shock up to 100 Gs, offering durability for factory automation and field measurement platforms. The AWM5000 Series is recognized for its venturi-type flow housing, enabling high flow mass airflow detection with minimal pressure drop.

This sensor is widely utilized in industrial, laboratory, HVAC, medical, and commercial settings. It is particularly useful in applications where monitoring and control of dry gas flow is critical, such as air and gas metering, process control, medical equipment, and automated testing. With a combination of precision, reliability, and robust construction, the Honeywell AWM5101VN delivers performance for advanced sensing requirements.
