Pyroelectric Infrared Detectors
Dual Channel Detector LHi 814 G.../G...
Two seperate elements, size 1,5x1,5
Individual spectral window for each element
Designed for Gas Analysis applications
The
LHi 814
pyroelectric infrared-detector series is specially designed for gas
analysis and monitorring applications. It includes two pyroelectric elements,
each having a FET in source follower connection. Thus two outputs are given.
The detector is encapsulated into
TO-5
housing with two seperated spectral
narrow band infrared windows. There are many filters available for the selected
spectral bandwidths. Often one channel is used as reference channel.
