71 PRODUCT DATA SHEET MPS2SENS Two channel premium pyroelectric detector with high signal-noise-ratio PRODUCT DATA SHEET > Pyroelectric IR detectors > MPS2SENS | © Micro-Hybrid-Electronic GmbH | 2022-06 | All rights reserved. Applications ■ NDIR gas analysis ■ Gas monitoring Product benefits ■ Higher precision and signal-noise-ratio ■ Less sensitive to external interference due to internal signal amplification ■ Less influence of temperature fluctuations due to low thermal mass ■ Higher read-out rate up to 100 Hz ■Short response time ■High end solution for demanding applications Additional product information The absorption of the incident infrared radiation forms a temperature gradient across the detector membrane. Due to the pyroelectric properties of the sensor material, this temperature change is converted into a charge change which can be measured at the electrodes of the sensor chip. Micro-Hybrid's CPM (ceramic pyroelectrical material) pyroelectric detectors use sensitive elements based on MEMS technology. Features ■ 2 chips with MEMS based CPM membrane ■ Broad spectral sensitivity 2 - 15 pm, optimized from 3 - 5 pm ■ High responsivity with modulation frequency up to 100 Hz ■ Low microphone effect referring to low membrane mass ■ Very low temperature dependence ■ Amplified signal in current mode The pyroelectric element consists of a approximately 0.5 pm thick thinfilm CPM mounted on a modified silicon-based membrane which is produced by a DRIE back-etch process. The front electrode is optically transparent allowing infrared radiation to be absorbed by the active area. This area has a broad absorption range from 2 - 15 pm.

71 PRODUCT DATA SHEET > PYROELECTRIC IR DETECTORS > MPS2SENS Article Type Filling Temp. Temp. Aperture Gas to Our infrared detectors on pyroelectric basis, MPS series, are based on one or more MEMS sensor chips in a hermetic packaging, which in addition to a silicon carrier contain the piezoceramic PZT (lead zirconium titanate) as a functional thin film in small quantities. The substance compound PZT is excluded from the restriction according to Annex III (7c. I). Furthermore, our pyroelectric-based infrared detectors are exempt from RoHS Directive 2011/65/EU Article 4 (1) according to...
