Miniaturized Thermocouple Scanner


Miniature Thermocouple Scanner

Product Description

The all new miniaturized multichannel thermocouple scanner comes with a handful of features in a compact ruggedized enclosure. Developed as part of an integrated data acquisition system, the thermocouple scanner comes with 16 input channels and built+-in cold junction compensation. Screw type terminals accessible from the top make it easy to connect the thermocouples. All 16 channels share a single signal conditioning path using time shared multiplexing controlled by the master controller. A high speed 18 bit ADC digitizes the data and transfers the data stream to an Ethernet port in real time.
