Excelitas Technologies Corp.
Pyroelectric Detectors and Sensors electronic circuitry. With Excelitas, you are not limited to off-the-shelf designs; customized designs are also possible. Learn More. For a standard Dual Element Detector, the signals are in the range of 3000 V/W. That means the infrared radiation of a person moving at a speed of 1 m/s with a distance of 10 m from the detector generates a signal of some mV. Output signals can be analog as well as digital. Pyroelectric Detectors utilize the "Pyroelectric Effect" for non-contact radiation... (read more)Browse Temperature Sensors Datasheets for Excelitas Technologies Corp.
Two-Color Sandwich Detectors The Photovoltaic Detector series is utilized for applications requiring high sensitivity and moderate response speeds, with an additional sensitivity in the visible-blue region for the blue enhanced series. The spectral response ranges from 350 to 1100 nm, making the regular photovoltaic devices ideal for visible and near IR applications. For additional sensitivity in the 350 to 550 nm region, the blue enhanced devices are more suitable. These detectors have high shunt resitance and low noise...

RTDs Resistance Temperature Detectors In operation, a small excitation current is passed across the element, and the voltage, which is proportional to resistance, is then measured and converted to units of temperature calibration. The RTD element is manufactured by winding a wire (wire wound elements) or plating a film (thin film elements) on a ceramic or glass core and sealing the element within a ceramic or glass capsule. Since most RTDs have a low initial resistance, often 100 ohms, and have a small change in resistance per unit...
