LTC6081/LT1025 Type K Thermocouple Signal Conditioner with ±350V Protection from Accidental Contact and Cold Junction Compensation

Dec 9th 2003
A high input impedance amplifier permits the use of large valued input resistors and retains signal accuracy. This is very useful for protecting both the amplifier and cold junction compensator in thermocouple applications as the sense element can often be inadvertently connected to destructive voltage potentials. The 1MΩ ...

High Resolution Battery-Powered Robust Type K Thermocouple Signal Conditioning Amplifier with Cold Junction Compensation

Nov 23rd 1999
The circuit is used as a plug-in adapter for common digital multimeters and is completely portable. This circuit employs the LT1025 thermocouple compensator to improve accuracy over a wide range of ambient conditions and is mounted close to the thermocouple connection points for optimal thermal tracking. It precludes the need ...
