Abstract
The invention relates to a radiation sensor device comprising a housing and a plurality of radiation sensor modules secured to the housing. Each radiation sensor module comprises a radiation sensor arranged to detect radiation incident on the radiation source module. Preferably, each radiation sensor module contains an entire so-called optical train to allow for calibration of the detector (e.g., photodiodes, photoresistors and the like) without disassembling all the components of the module.
Claims25
An ultraviolet radiation sensor device comprising:
- a device housing having (i) a first longitudinal axis and (ii) at least two ultraviolet radiation sensor modules annularly disposed on the housing so as to face outward in different directions from said first longitudinal axis, each radiation sensor module comprising:
- a radiation sensor arranged to detect an ultraviolet radiation incident on the radiation sensor, and
- a module housing having an ultraviolet radiation transparent window through which the incident ultraviolet radiation passes to contact the radiation sensor, the radiation transparent window oriented exteriorly with respect to the device housing, the radiation sensor being oriented interior of the transparent window with respect to the device housing,
- a radiation filter coupled to said module housing and disposed exteriorly of said radiation sensor, and
- a calibration element configured to calibrate said radiation sensor for the particular filter disposed exteriorly thereof.
Ultraviolet radiation sensor apparatus submersed within a fluid flow, said apparatus comprising:
- a housing having a longitudinal axis and an outer surface disposed within said fluid flow;
- a plurality of ultraviolet radiation sensor modules annularly disposed on an outer surface of the housing and within the fluid flow so as to face outward in different directions from said longitudinal axis;
- each ultraviolet radiation sensor module having (i) a radiation sensor and (ii) an ultraviolet radiation transparent window through which incident ultraviolet radiation passes to contact the radiation sensor, the radiation transparent window being disposed on the outer surface of the housing and within the fluid flow;
- each ultraviolet radiation sensor module also having a radiation filter disposed exteriorly of said radiation sensor, and
- each ultraviolet radiation sensor module further having a calibration element configured to calibrate said radiation sensor for the particular filter disposed exteriorly thereof.
