Description
- The narrow-band filter of the MPS2SENS LiTaO3 carbon dioxide with a CWL of 4265 ± 25 nm and a HBW of 120 ± 10 nm is optimized for the measurement of carbon dioxide (CO2) with reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm). The pyrodetector with a detectivity of up to 2.0*108 cm√Hz/W and sensitivity of 120000 V/W is suitable for NDIR gas analysis applications in the fields of agricultural, industrial, medical, environmental and power engineering. With a read-out rate of up to 25 Hz, the pyroelectric detector provides reliable and effective measurement results.
- Internal signal amplification makes the detector less sensitive to external interference. In-circuit compensation also ensures reliable and stable measurements. The influence of temperature fluctuations is thus kept low.
- In the standard version, the MPS2 LiTa detector is available from stock.
- 2 optical sensor chips with a LiTaO3 layer form the basis of this pyroelectric detector. When IR radiation hits the optical sensor, the lithium tantalate layer heats up and the polarization changes accordingly. This charge transfer can be amplified as an electrical signal and then evaluated. The detector can be used at ambient temperatures between -20 and 85 °C.
