Pyroelectric Infrared Detectors
Dual Element Detector
NEW: Integrated amplifier
High output signal
Design for special alarm applications
The
LHi 2068
pyroelectric infrared-detector is a new unique design with dual
element configuration and integrated amplifier. Two elements are connected in
series and feed the signal into an operational amplifier.
It offers a highly stable responsivity with excellent common mode performance
(match) and low noise, with extended frequency performance .
