PDV-P5002 Application Field and Working Principle

Optical sensors, such as photo detectors and CdS cells, are devices that detect and measure light and process the resulting signal. The PDV-P5002 photo detector manufactured by Photon Diagnostics is one type of such device, which is primarily used in spectrophotometric analysis and chromatography research. This article will discuss the application field and working principle of the PDV-P5002.The PDV-P5002 photo detector is a single-channel CdS detector, which is designed for use in minimum noise environments such as a photometric system. It has a wide spectral response range from 180nm to 800nm, and features low dark current, high input capacitance, and high linearity. Because of this, the PDV-P5002 is suitable for use in demanding applications such as sample analysis and biological research, as the output can accurately reflect the concentration of the sample.The PDV-P5002 photo detector is composed of a photoconductive cell and a supporting circuitry. When exposed to photons, the photoconductive cell generates electron-hole pairs, which leads to a current that is proportional to the light intensity. The current is then amplified by an amplifier circuit, producing a corresponding voltage. This voltage can then be further processed by connected data acquisition systems.The PDV-P5002 photo detector can also provide temperature compensation for incoming light sources. This is done via its integrated set of temperature-sensing elements, which help ensure accurate responses even when the temperature changes, such as when the device is moved from a cold environment to a warm one.In addition, the PDV-P5002 also has a range of communication interfaces, including a GPIB, RS-232, and parallel ports. This makes the device suitable for remote applications, such as over internet networks, as the data can be easily streamed or download.To summarize, the PDV-P5002 photo detector is a single-channel CdS detector suitable for spectrophotometric analysis and chromatography research. It offers an impressive range of features, including temperature compensation, low dark current, and high linearity, making it a reliable device for measuring and analyzing samples. Furthermore, the multiple communication interfaces available increases its usability, allowing it to be deployed in remote systems as well.
