摘要：
An infrared sensor for gas metering appliances consisting of a metering chamber with an infrared source and an infrared sensor. The metering chamber is connected to the atmosphere via an anti-dust and anti-damp filter. The metering chamber is arranged in a protective housing having gas inlets and outlets. Connection to the metering chamber via a gas exchanger orifice and an anti-dust and anti-damp filter is not of a pressure-proof design based on normal pressure conditions. The infrared source and the infrared detector are integrated in the wall of the metering chamber and held therein. The infrared source is a lamp. The infrared source and infrared detector have a fail-safe power supply.
