Four Channel Pyroelectric Sensor - Exhaust Environmental

Added to your shopping cart

Infrared Detectors Quad Channel Sensor; Filters: CO2 (carbon dioxide) (4.26um/180nm); CO (carbon monoxide) (4.64um/180nm); CH4 (methane) (3.30um/160nm); Reference (3.91um/ 90nm).

Pyreos Thin Film Quad Channel Pyroelectric Sensors are highly stable four element sensors that provide high sensitivity with fast frequency operation in a TO39 package. These current mode sensors offer up to 100Hz data monitoring and feature internal CMOS trans-impedance amplifiers with 10GΩ feedback resistors. These feedback resistors output voltage signals are centered around half the supply rail. The thin film quad channel pyroelectric sensors are able to detect a variety of gases when used with different combinations of filters. These sensors with additional two channels will increase the accuracy of gas detection.
