Ultraviolet selective thin film sensor
TW30SX
Features of the TW30SX UV Sensor
The UV Sensor TW30SX is our Big Seller. Our customers treasure it’s broad application
range, it’s high reliability and robustness and it’s competitive price. Overview on the
advantages:
•
•
•
•
•
Broad Band UVA – UVB spectral response
Hermetically sealed metal housing and UV-glass window
high photocurrent even if illuminated with very low radiation because of big active area.
optimally suited for inexpensive sun dosimetry
we
are able to manufacture up to 2.000.000 pcs. per year.
Was leistet der TW30SX UV-Sensor?
