G-MAFCO-005 55-70MM Mass Air Flow Sensor is a thermodynamic sensing element for the bidirectional measurement of mass air flow in a well defined channel. It is dedicated for applications with high reliability requirements such as medical or industrial gas flow applications. Mounted directly within the flowing media the LMMH03 is sensitive against the heat transfer on a micrometer scale. This heat transfer is detected by a micro-machined silicon device which is mounted on ceramic substrate defining the geometry of the sensing
The functional principle of the LMM-H03 is a hot film anemometer, which is the thin film version of the hot wire anemometer. A thin film heating element (heater) is heated to a defined temperature difference with respect to the air. At zero flow there is heat dissipation due to the thermal conductivity of the air. With applied flow the heat dissipation increases steadily with the flow rate. The sensing element can be operated at Constant Power and Constant
Features:
- Highly reliable and long term stable
- Fast reaction time
- Can be adapted to various flow channel geometries
- Can be used for almost all kind of gases and volatile substances
Package Includes:
- 1 x G-MAFCO-005 55-70MM Mass Air Flow Sensor
