AS-MLV-P2 − Electrical Characteristics
The sensor elements operate at an elevated temperature. The
elevated temperature is realized by means of the Pt heater
which is implemented within the silicon nitride membrane. The
recommended operating temperature for the AS-MLV-P2 is
300°C, which is equivalent to an applied power of approx.
34mW at room temperature.

Electrical Characteristics
Note(s):
1. This lifetime can only be reached with respect to the recommended operation of the sensor. Especially the maximum ratings during
operation have to be followed carefully. With this background, the AS-MLV-P2 is maintenance free and shall require no replacement
during specified lifetime.
2. Pt heater element operates at 300°C
