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.
Abstract:
The invention relates to a radiation sensor device comprising a housing, a radiation sensor secured with respect to a first portion of the housing and a heat pipe in thermal communication with the first portion of the housing, the heat pipe being configured to transfer heat from portion of the house to a second portion of the housing remote from the first portion of the housing. The heat pipe may be used advantageously to transport or transfer heat away from the sensor components of the device to an area remote therefrom. The heat pipe can be used to transfer heat at a rate that is thousands of times higher than copper. The radiation sensor device may be used in an ultraviolet radiation fluid treatment system such as an ultraviolet radiation water disinfection system.

Abstract:
A photodetector for detecting photo intensity through a liquid comprises a body (15), which defines a chamber (17) that is open at one end, a photosensor (14) mounted to the body and arranged to sense light entering the chamber (17) through its open end, a layer of air being disposed in the chamber between the photosensor and the open end of the chamber. The layer of air forms a barrier between the photosensor (14) and the liquid and thus slime and other matter is unable to build up in front of the photosensor.
