R2868 Hamamatsu UVtron Flame Sensor with Driver Board

Flame Sensor from Hamamatsu, P/N: R2868

This UV Flame Sensor operates under DC 325 +/- 25V. It response to UV Spectral 185~260nm, which is emitted under lighting of flame. Its suited for use in flame detectors and invisible discharge phenomena such as corona discharge of high-voltage transmission lines. This part is generally used in many robotics project for flame detection.


The sale will bundle with an In-House Developed R2868 Driver board . It provides the necessary driving voltage (DC 325V) for R2868 with Input ranging from DC 3.6V to 12V. Unlike the C3704 Driving and Signal Processing Board from Hamamatsu, the Signal Processing circuit is not included in this driver board. We have designed a separated signal processing board specially for its purposes. The direct output from the R2868 has been pulled to a header pin, whereby it can be easily interface to an MCU for further processing. Inverter output pulse can be also acheived by just soldering additional Schmitt Trigger IC which is not mounted on default. The board can be configured to work in power safe mode just by depressing the power saving push button, whereby the ON and OFF Power to R2868 is configured using two resistor, Rx & Ry. Alternatively, if power saving is not critical, the R2868 can be configured to operate in "Always ON" mode by setting the power saving push button to OFF Mode. This board allows the R2868 to be mounted Horizontally or Vertically depending on User's application. To mount R2868 Horizontally, just blend the legs of R2868 and slolder onto U4. If Vertical Mount is preferred, soldered it onto U1. R2868 Schematics diagram will be provided in digital format upon purchases.


You have to manually solder the R2868 Sensor onto the Driver board. Free Shipping via Registered Air Mail services.
