Flame sensor module

C16956-02

This flame sensor module consists of a UVTRON® flame / discharge sensor integrated with a driver circuit and a signal processing circuit such as for processing of background noise.
Just supplying a DC voltage to this module will start to detect UV light. Besides acquiring information such as UV detection signals and sensitivity (detection count), this module allows checking the UVTRON® operation with the internal UV-LED. The light-receiving section of this module has a G1 female thread for easy connection to combustion equipment.

*1: Typical value measured with a light intensity of 10 pW/cm2 at a wavelength of 200 nm. In actual use, sensitivity varies depending on the wavelength and intensity of the incident UV light.

*2: Measured under room lighting (approximately 500 lx) and recommended operating conditions.

*3: Estimated life of the R14388 operated at room temperature when UV light is continuously incident under recommended operating conditions. The life varies with the ambient temperature, etc.

*4: min-1 indicates counts per minute.
