Applications
The U2802A thermocouple input device is designed for robust and demanding industrial
applications. This product is suitable and ideal for thermocouple measurement applications
such as;
Product thermal analysis and characterization
Environmental chamber profiling
Process monitoring in consumer electronics markets
Material properties testing in education environments
Study of electronic temperature properties
Appliances testing
The Keysight U2802A is a 31-channel
thermocouple signal conditioning
module with a built-in thermistor
for cold junction compensation.
The U2802A is designed to convert
low input voltage signals (less than
±100 mV) from a thermocouple into
an output voltage range suitable for
data acquisition devices (±10 V).
The U2802A device is to be used in
conjunction with the Keysight U2355A
or U2356A model DAQ device to
enable temperature measurements
using thermocouples. It works as
a standalone device attached to a
single DAQ device via two SCSI-II
68 conductor cables. Designed with
the compatibility to complement
eight standard thermocouple types, it
caters to a wide range of applications
in various industrial settings.
