Why Thermopiles?

A Reliable and Durable Platform for Temperature Sensing

Sensor Detector = Temperature. Precise knowledge of a material, cell or living tissue temperature is a core requirement of virtually every industrial process, medical procedure or biomedical culture. Analyzing temperature is essential to monitoring the weather and the physical environments for humans, animals and crops. Fire detection is a key requirement for safety of our homes, work places, medical centers, and combat vehicles and aircraft. Dexter Research thin-film infrared sensor technology has been the most reliable and durable platform for any non-contact infrared temperature measurement. Read more »

The Hard-Working Core of Our Low-Cost Motion Sensor

Motion. We depend on it for all of our work processes and home security. But we also measure motion and regulate it. We want to know when someone is present and automatically light the way in the dark or open a door for convenience. We may want to turn on video surveillance or detect an intruder. At the core of Dexter’s Thermacon passive infrared motion sensor is a low-cost, yet highly reliable thermopile detector, manufactured right here in the Dexter Research Center. Read more »

For Reliable Gas Detection Wherever It’s Needed Most

Oxygen. It’s life itself. No wonder Dexter Research’s thermopile infrared gas sensors are used in home, office and health safety systems to detect dangerous gases that impact oxygen levels and other gas leaks. Our infrared gas detectors have also served as multi-gas analyzers in hospital operating rooms around the world to assure patient safety during anesthesiology. Read more »
