1. [Amps] Monitoring temperature (score: 1): Author: Bill Turner <dezrat1242@yahoo.com>; Date: Sun, 09 Jun 2013 12:04:45 -0700; I would appreciate any suggestions for monitoring temperature on a solid state power amp. I have used the LM34 with success in the past, but not in the presence of strong RF fields. After all, it is; /archives//html/Amps/2013-06/msg00204.html (6,899 bytes)

Re: [Amps] Monitoring temperature (score: 1): Author: Tom Thompson <tlthompson@qwest.net>; Date: Sun, 09 Jun 2013 14:19:29 -0600; Hi Bill, I used the LM35A on my solid state kilowatt and solid state 600 watt amplifiers. With the proper filtering it works fine. Here is a circuit from my web site. http://tomthompson.com/radio/600; /archives//html/Amps/2013-06/msg00205.html (8,452 bytes)

Re: [Amps] Monitoring temperature (score: 1): Author: Tomm V Aldridge <taldridge@gmail.com>; Date: Sun, 9 Jun 2013 14:29:52 -0700; Bill, I would try the LM34 with heavy bypassing of both the Power and output to return. Keep your loops very small and then connect through both a common mode and differential mode inductors at both; /archives//html/Amps/2013-06/msg00206.html (8,197 bytes)
