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.
