QUESTIONS

#1 - We notice that you have a number of Flow/Fume Hoods. Would you like to have the differential pressure monitored in each of these? If so, please specify the pressure ranges.

#2 - We also notice that you have one or more LN2 Dewars. Would you like the level and/or temperature in these monitored?

#3 - Is the Ethernet connection between the individual sensors and the PC hosting the system a private network (no other systems use the network)? If so, is it wired point-to-point from the sensor to the PC?

#4 - Will 120VAC be available at each particle counter location?

ANSWERS

#1 - No we're not interested in the pressures on the Flow/Fume Hoods.

#2 - No we do not need the temperature/level monitored on the LN Dewars.

#3 - The PC is hosted on a private LAN (no outside internet connection).

We need the sensors to be wired to the computer in whatever way makes best sense, the LAN makes use of Ethernet connections so that would be best.

#4 - Yes 120VAC will be available at each particle counter location.
