The AM25T 25-Channel Solid State Multiplexer increases the number of thermocouples that can be measured by a Campbell Scientific datalogger. The multiplexer interfaces with the datalogger and adds terminals for wiring additional thermocouples or other low-level voltage output sensors.

Benefits and Features

Greatly increases the number of thermocouples a datalogger can measure
Multiplexes up to 25 thermocouples
Includes an on-board PRT that serves as a reference junction
Allows several AM25Ts to be controlled by one datalogger increasing the number of thermocouples that can be measured
Uses a metallic, internal ground plane to reduce thermal gradients, which ensures more accurate measurements
Provides a vertical package for a smaller “footprint” that makes it easier to fit in a crowded enclosure
Supports a maximum cable length of 500 feet when lightning protection is used
