Best Position to Install a UV Intensity Sensor on UV Sterilizers or UV Cell

1. Can we install the UV intensity sensor at the end of the UV sterilizer (or UV cell)?

Yes, you can install the UV intensity sensor at the end, but we do not recommend it. Sensors installed at the end may only capture the UV light from lamps closest to them, leading to inaccurate readings. This can affect the effectiveness of your sterilization process.

2. Where is the best place to install the UV intensity sensor?

The best place to install the sensor is in the middle of the UV lamp flange or centrally within the UV chamber. This allows the sensor to measure UV light evenly from all the lamps, ensuring more accurate monitoring and optimal disinfection performance. 

3. Why is installing the sensor at the end not ideal?

When the sensor is installed at the end of the UV cell, it may not capture the full UV output from all the lamps. The lamps closest to the sensor will dominate the readings, while those farther away won’t be measured accurately, leading to unreliable results.

4. Can you show us where the UV intensity sensor should be placed?

Yes! See the diagram below for the best placement of the sensor within the UV sterilizer:
