FLAME SENSOR UV TRON ®  
R9454, R9533  
Quick Detection of Flame from Distance,  
Compact UV Sensor with High Sensitivity and Wide Directivity,  
Suitable for Flame Detectors and Fire Alarms.  
The UV TRON R9533 and R9454 are UV sensors that utilize the photo-  
electric effect from metal and gas multiplication. These devices are sensi-  
tive only to UV light in a spectral range of 185 nm to 260 nm. This makes  
them easy to use since they do not require optical visible-cut filters. Their  
electrodes are optimized for ruggedness to resist mechanical shocks up  
to 10 times (10000 m/s2) greater than the conventional UV TRONs.  
The R9533 is a head-on type (UV light enters through the top of the  
bulb) that easily installs into equipment. The R9454 is a side-on type  
(UV light enters through the side of the bulb) whose outer appearance  
resembles the conventional flame sensor R2868. Both these types util-  
ize a plate cathode and feature high sensitivity and a wide field of view  
(directivity).  
APPLICATIONS

NOTE: 1This is the maximum momentary current that can be handled if its full width at half maximum is less than 10 µs.  
2If the tube is operated near this or higher, the service life is noticeably reduced. Use the tube within the recommended current values.  
3Measured under room illuminations (approximately 500 lux) and recommended operating conditions. Note that these values may increase if the  
following environmental factors are present.  
1. Mercury lamps, sterilization lamps, or halogen lamps are located nearby. 2. Direct or reflected sunlight is incident on the tube.  
3. Electrical sparks such as welding sparks are present. 4. Radiation sources are present. 5. High electric field (including static field) generates across the tube.  
4These are representative values for a wavelength of 200 nm and a light input of 10 pW/cm2. In actual use, the sensitivity will vary with the wavelength  
of the ultraviolet radiation and the drive circuitry employed.
