AS-MLV-P2 − Detailed Description
AS-MLV-P2 heater and inter-digital electrode structures use
Platinum and are implemented in an approximately one
micrometer-thin silicon nitride membrane to achieve ultimate
stability and lowest possible power consumption. A highly
sensitive and long-term stable polycrystalline tin
dioxide-based sensitive material is deposited on the
inter-digital electrodes. At an elevated operation temperature
of approx. 300°C, this catalytically active material shows a gas
concentration dependent resistance change.
Sensing Properties
The AS-MLV-P2 sensor component shows a strong sensitivity to
a wide range of reducing gases as can be seen in Figure 6. Please
note that those results may vary due to different environmental
conditions.

Sensor Sensitivity: Sensitivities for various gas concentrations, this graph shall just give an indication and can
vary slightly from sensor to sensor.
