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.
