Cal Sensors launched PIREPlus, a high-output, high-pulse rate emitter that can be pulsed as a source of blackbody radiation for near-to-far infrared applications at 180Hz with 50% modulation depth. The PIREPlus has a high pulsing speed, and maximizes signal to noise performance, expanding the measurement dynamic range and resolution for trace gases with low parts per million. The solid state emitter offers high output (4x10-2 watts/cm2 at 1 inch from filament) and includes integrated drive electronics.
The PIREPlus is well-suited for a variety of applications, including industrial and medical gas analysis, environmental monitoring, process control instrumentation, spectroscopy, and plastics sorting. The pulsable emitter offers enhanced signal-to-noise ratio, is compatible with a wide range of detector technologies, and comes in an industry-standard T0-5 header package.
The radiating element in PIREPlus is an ultra-thin metallic foil configured to ensure radiation from both sides of the heated foil is efficiently directed out of the package along the optic axis. The foil material has an emissivity of 0.88 and closely emulates a blackbody source in spectral distribution. PIREPlus emitters are designed to operate at a rated maximum foil temperature of 1000° Kelvin and are offered with a standard integrated reflector to provide near collimated and uniform radiation output. A variety of elliptical reflectors with varying focal lengths are also available for coupling into optical fibers and other applications.
The PIREPlus comes with integrated drive electronics in an industry standard 14 pin-dip IC package. The user-friendly drive electronics are voltage variable and allow users to select from a wide range of frequencies between 1Hz and 500Hz according to their specific application needs. A special feature of the drive electronics is the ability to provide peak pulse temperatures independent of the pulse frequency. This ensures high output for applications. The product is compatible with a wide range of IR detector technologies.
