Infrared detector - dual, triple or quad channel - for gas analysis
and flame detection sensors where more than one element or event is
to be detected.
Infrared detectors
exhibit <0.1% crosstalk, with optional low-microphonic
protect from vibration, thermal compensation and integrated
JFETs or OpAmp.
Infrared detector comes in TO8 and TO39 packages. Beamsplitter option allows for single light path where a
narrow beam is to be measured and minimal issue with any
contamination on device window.

New angular resolving pyroelectric flame
detector
PIA-903-X001
With our standard pyroelectric detectors
(e.g. single detector LME-551 or quad
detector LMM-244) it is possible to detect a
flame and its composition at a distance of
more than 50 meters. Until now the position
of the flame inside the field of view (FOV)
was not resolvable.
As an upgrade to standard tri-band flame
detectors, the new PIA-903 detector with 3 x
3 element array and integrated optics is
able to provide additional spatial
information about the observed scene for a
rough angular location of the flame.
Calculating the signal ratio of neighbor
channels offers an interpolation of the
angular position inside of a 90° conic FOV.
A combination of two or more flame sensor
units can produce a 3D coordinate of a fire
position.
