It has been proposed that 30min occupancy sensors are to be used in the cleanroom bays and chases (one at each end of each bay and chase). Personally, I have a lot of reservations about using such sensors given safety concerns created by potential blind spots, especially when staff are working in tight spots around various processing tools. In addition, I have concerns about sensitivity given the noise and vibration in many areas of the lab. Does anyone have experience (good or bad) with such sensors in a cleanroom environment?<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Best Regards,<o:p></o:p></p><p class="MsoNormal"><br>Matt<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">-- <br><b>Matthew T.
