Three-band infrared flame detector

When a substance burns, it produces smoke and heat, and also produces visible or invisible light radiation that is not found in the atmosphere. Flame detector, also known as photosensitive fire detector, is a fire detector used to respond to the light characteristics of fire, that is, to detect the light intensity of flame burning and the flicker frequency of flame. Infrared flame detector is a flame detector that is sensitive to the longer wavelength infrared light radiation in the flame. According to the different detection bands, it is divided into single band, dual band and three band.

Picoamp Current Measurement Evaluation Kit

The picoamp (pA) level current measurement (hereinafter referred to as PAM) evaluation kit developed by Shijian Company covers the complete functions of detector signal processing in analytical instruments. The kit includes a current input conversion board, a voltage input buffer board, a data acquisition board and There are four components of the pin conversion board. Using this kit, customers can choose different daughter board combinations according to the characteristics of their products, quickly evaluate the performance of the devices in this kit, and shorten the design cycle. Both the current input conversion board and the voltage input buffer board use ADI's latest femtoamp (fA) input bias electrometer amplifier ADA4530-1, and the data acquisition board uses ADI's AD7172-2, 24-bit 31.25 kSPS. Σ-Δ ADC. The pin conversion board has been designed to make the pins of ADA4530-1 and AD549 and their power supplies compatible. Customers can directly evaluate the performance of ADA4530-1 on original products using the AD549 chip without re-making the board. This evaluation kit also provides host computer software for real-time waveform display and data analysis.
