What is a TOCON?
A TOCON is a 5 Volt powered UV
photodetector with integrated amplifier converting UV radiation into a 0
… 5V voltage output. The V out pin of the TOCON can be directly
connected to a controller, a voltmeter or any other data analyzing
device with voltage input. Highly modern electronic components and a
hermetically sealed metal housing with UV glass window eliminates noise
caused by parasitic resistance paths inside the package or EMI. A TOCON
is a perfect solution for each industrial UV sensing application
starting from flame detection at pW/cm2 level up to UV curing lamp control at W/cm2
level. This thirteen orders of magnitude range is covered by ten
different TOCONs that differ by their sensitivity. The TOCONs are
produced as UV broadband sensors or with filters for selective
measurement.
Silicon Carbide (SiC) detector chip inside
Sophisticated electronics make a TOCON a
reliable component in harsh environments as well as for extremely low or
extremely high UV radiation. But what makes the TOCON a quasi eternally
living sensor is the sglux in-house produced SiC detector chip featured
by a PTB-reported extreme radiation hardness.
