Thermocouple Conditioner

Octal Thermocouple Conditioner with Enhanced Accuracy

The 28208A 8-Channel Thermocouple Conditioner provides eight channels of conditioning for all commonly used thermocouple types. The 28208A consists of a low-drift programmable differential pre-amplifier, a 4-pole programmable filter and a programmable post-filter amplifier.

The 1U rach mountable Isothermal block with integral digital temperature sensor provides pluggable screw terminal connection to the thermocouple wires with better than 0.15 degree accuracy in reference junction compensation.

The 28208A 8-Channel Thermocouple Conditioner is a member of the Precision 28000 family of signal conditioners.
