Airflow Sensors

Posifa Technologies develops and manufactures thermal silicon sensor chips in California (Silicon Valley). Air flow sensors / mass flow sensors for air and gases are manufactured and calibrated in the Posifa factory in China or in Taiwan. Measuring ranges from 0…200 sccm (cm³/min) to +- 800 SLM (standard liters / min.) are available.

Linear output signals, analog and digital, offer an ideal connection to the electronics for each application. The sensor chip developed and patented by Posifa is very robust against particles, moisture and pressure shock.

The flat surface is made of silicon carbide (SiC). The sensors operate without a cavity under a fragile microbridge. In addition, the PMF86000 and PMF83000 airflow sensors are coated with Parylene.

This means that the Posifa sensors are significantly more durable than competitor products. In addition to the standard sensor with a linear output, Posifa offers a directly interchangeable version with the competition Honeywell. The housing, operating and output voltages are the same. The customer can replace Honeywell with Posifa without further adjustment. Here are the sensors: AWM3300V with PMFc3300V; AWM3100V with PMFc3100V; AWM720P1 with PMFc720P1; AWM43300V with PMFc43300V.

In addition to standard products, we offer customer-specific calibration and mechanical adaptations. The Posifa R&D team provides extensive support with application-related questions. Call us or use the contact form, BS-rep and Posifa will support your design.
