Patent Images
1. A measurement device adapted for in situ light intensity sensing from within an environment comprising:
- a housing adapted to enclose a control system and fluidly seal the control system from the environment, the housing having an outer wall and a channel fluidly connected to the environment at one or more locations,the control system comprising a controller, a light receiver component and a wireless data transmitter component,the light receiver disposed within the housing to receive light from the channel and output one or more signals indicative of light intensity, andwherein the control system is configured to;
receive the one or more signals indicative of light intensity from the light receiver, andoutput a signal indicative of light intensity to the wireless data transmitter, andwherein the housing comprises a first and a second shell section, the first shell section having an engageable sealing surface adapted to couple with an engageable sealing surface of the second shell section, and form, when engaged, a substantially hermetic shell that encloses the control system, wherein the sealing surfaces of the first and second shell sections are threaded, are adapted to engage by interference fit, are adapted to compress about an o-ring, are chemically or thermally bonded, or any combination thereof.
