UV-TIAMO v 3.0 Description The UV-TIAMO devices are using modern hybride technology to cancel unwanted signal disturbances caused by moisture or electromagnetic radiation. The stable 0…5V output voltage can be directly connected to a SPC controller or a voltage multimeter. No external amplifier is needed. The photodetectors work with a SiC sensing chip. SiC provides the unique property of extreme radiation hardness, near-perfect visible blindness, low dark current, high speed and low noise. These features make SiC the best available material for visible blind semiconductor UV detectors.

The voltage output signal is measured between pin OUT and pin GND. Please note that the theoretic maximum signal output is always a little less (approx. 5%) than the supply voltage. CAUTION! Wrong wiring leads to immediate destruction of the device. Application Note To make the photodiode running reliably, particularly in harsh environment, EMC compatibility and protection against dust, water, and mechanical influences is required. Below listed modules base on a SiC photodiode and guarantee this protection and safety. UV-probe: SiC based sensor modules in customizable industry grade housings (e.g. cosine response, water pressure proof, sapphire windows) and different electronic output configurations (voltage, current, USB, Can, LAN) to choose from.
