Introduction

The Agilent 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 Agilent

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. The U2802A is compatible with eight

standard thermocouple types and is suitable for a wide range of applications in

various industrial environment.
