Micro-Hybrid Electronic GmbH produces high performance pyroelectric detectors and NDIR gas sensors, as well as thermopile infrared detectors and IR sources. View the Micro-Hybrid video at the bottom of this page.
Pyroelectric detectors are available in voltage and in current mode, packaged in a TO-39 housing. The current mode is available with various amplification gains. The Micro-Hybrid pyroelectric detectors feature:
- 1.4um thick pyroelectric film with low thermal mass.
- Thermal time constant almost 10 times faster than traditional lithium tantalate pyroelectric detectors.
- Low sensitivity to microphonics.
- High temperature packaging option good up to 180°C /
356°F.
These new pyroelectric detectors are available in high temperature packaging with support electronics for use up to 180°C / 356°F. Micro-Hybrid is able to offer all of their IR components, thermopiles, pyroelectric detectors and IR sources in this high temperature packaging.
NDIR Gas Sensors / Detectors
An NDIR sensor (nondispersive infrared sensor) is a simple spectroscopic device often used as a gas detector. It is called nondispersive because the gas which passes through the sampling chamber is not pre-filtered. Instead, a narrow bandpass (NBP) filter is used in front of the detector to look at only the IR signal in the absorption band for that subject gas. Micro-Hybrid can produce detectors with up to 8 channels (thermopiles) and 6 channels (pyroelectric) for monitoring multiple gases. More
Micro-Hybrid GmbH is certified to TS 16949:2009 and ISO 9001:2008. Copies of these certifications are under Technical Notes. These certifications are a reflection of their commitment to quality and product improvement.
Applications include:
- Fire & Flame Detection
- NDIR gas analysis for industrial and medical applications
- Explosion detection
- Non-contact temperature measurement
- Spectrometers
- Process temperature monitoring
- Radiometers
- Analytical Instruments
- Far Infrared (FIR) thermopile detectors up to 300µm and beyond
Each channel of the pyroelectric detector is fitted to the application (including NDIR gas sensing or flame detection) by using an infrared filter or window. Micro-Hybrid has a broad selection of Standard Filters and Windows for these applications. Custom Filters and windows are also available.
To avoid damaging pyroelectric detectors during soldering and cleaning, consider using sockets.
