Since its founding in 1982, LASER COMPONENTS has specialised in IR sensors for use in flame detection devices. We manufacture lead sulphide detectors at our assembly plant in Arizona and pyroelectric detectors in Florida. A flame will flicker randomly at a rate between 1 and 20Hz when it is burned naturally, modulating any IR signal generated. Pyroelectric and lead sulphide detectors sense this modulated IR light and so can provide a warning of the presence of a flame. These instruments are widely used in the oil and gas industry to protect high value installations such as refineries, production platforms or petro-chemical plants.
The L2100X2020 is a single channel current mode sensor with a split supply of +/-5 V, the device is housed in a standard T0-39 4 pin package. LASER COMPONENTS can manufacture these detectors with an infra-red filter to target a narrow region of the electromagnetic spectrum. Using several of these devices in combination to focus on different wavelengths eliminates false alarms. The L2100X2020 has a long-expected lifetime making them ideal for this fit and forget application.
