Plug-and-play sensor prototype kit speeds time to market for gas analysis
The kit consists of two digital drive boards with integrated electronics, a one to four element detector, a PIREPlus emitter and developer´s software. Engineers have the option of buying the complete prototyping kit or a subset of the kit. The sensor prototype kit contains two digital drive boards with integrated electronics. Each board contains all the circuitry needed to drive the detector and emitter respectively and provides the analog to digital conversion necessary for computer control and analysis. It also contains a PbS or PbSe single-channel detector (SCD) or multi-channel detector (MCD). The MCD product family allows for the detection of up to four distinct materials/gases and provides exceptional channel isolation (>99.5%) and a compact TO-5 or TO-8 footprint with superior quality and reliability.
The four channel configuration offers significant opportunities for cost reduction and design simplification minimizing the need for multiple individual detectors and complex optics. System costs and footprints can be reduced up to 60% versus alternative single-detector designs. Though highly customizable for different applications across the one to five micron infrared spectrum, the MCD is available in a standard four-channel configuration with four discrete optical bandpass filters. This configuration supports CO, CO2 , and hydro-carbon (such as methane) gas analysis. Users can specify custom filters to meet specific application requirements.
The standard PIREPlus high-output, high-pulse rate emitter can be pulsed as a source of blackbody radiation for near-to-far infrared applications at 180Hz with 50% modulation depth. With a pulsing speed 18 times faster than alternative technologies, the PIREPlus maximizes signal to noise performance, optimizing the measurement dynamic range and resolution for trace gases with very low parts per million. The solid state emitter offers high output (4×10-2 watts/cm2 at 1 inch from filament) and fast pulse rate without the added expense of having to build in optical choppers or mechanical modulators as is often done with incandescent bulb emitters and covers a much wider spectrum than high-pulsing IR LEDs which focus on only very narrow bandwidths. The pulse rate is adjustable from 1Hz to 200Hz via variable voltage input to meet specific application requirements. A special feature of the drive electronics is the ability to provide peak pulse temperatures independent of the pulse frequency. This ensures the highest output for any application.
