Re: High density thermal diode monitoring

Hey Ned,

Along the same price per channel, but maybe a second unit to compare with is the Omega CYD218E.  The one in the pic is a single channel, see the manual at the bottom for the 8 channel (CYD218 series).

Subject: High density thermal diode monitoring

Hello all -

Has anyone implemented a cost effective solution for monitoring large quantities (~96) of thermal diodes for cryogenic temperature monitoring (down to 2K)?  The solution proposed here is either the Lakeshore Model 218 or Model 224, both of which are ~$250/channel ... I was hoping to find something cheaper.

Any proven alternatives?

Thanks -

   Ned


PS: I searched tech-talk and only found solutions for RTDs or thermocouples ...
