Jim, Thanks for following up on this. The thermoswitch that I'm looking for closes on reaching a trip temperature of 78C. The original unit was made by Princo. I wonder if your friend could tell me if he has any leads on a 78C thermoswitch.
Thanks again, Russ -----Original Message----- From: Jim Hall <[EMAIL PROTECTED]> To: time-nuts@febo.com Sent: Wed, 3 Sep 2008 8:04 pm Subject: [time-nuts] Description - GR 1120-AB Frequency Standard Today I visited a friend who collects all sorts of old electronics and asked him about mercury thermometer sensors. Turns out he had several from various GR pieces of equipment. Some are in a straight shape with "trip" temperatures of 50 or 60 degrees C. One is at a 90 degree angle with a 60 degree C trip point. I'm sure it is a very long shot but I wondered if any of these might work for the frequency standard you are rebuilding. Most of the above temperature sensors were built by "Precision". I have the part numbers. What do you think? Does it sound like any of these could be replacements for your unit?
