The VXI Technology EX1048 48-Channel, Precision Thermocouple Instrument is a
combination of measurement performance and integrity, configuration flexibility, package
density, and network connectivity makes it the most powerful, yet easy-to-use, instrument of its
kind. The EX1048 is a complete, self-contained temperature measurement system that
communicates over Ethernet. Unlike other data acquisition offerings in its class, the EX1048
offers a tightly integrated solution that frees the user from the complexity of marrying terminal
blocks, signal conditioning cards, digitizer, power supply, and chassis together.
The EX1048 also provides a level of measurement integrity and channel independence that far
exceeds the typical data acquisition system. Absent are caveats about scanning speed, channel
order, and overload effects. In the EX1048, channels have no influence on each other, regardless
of scanning speed or channel state. Excellent common mode rejection performance provides
immunity from not only power line interference, but also high frequency noise. Moreover, it aids
in maintaining overall system integrity by offering a high-performance open thermocouple
detection system.
The EX1048 provides a high level of configuration flexibility as well. Each channel can be
configured independently with regards to measurement function, hardware filter setting, and limit
values. In addition to measuring all standard thermocouples, the EX1048 can be programmed with
user-defined thermocouple polynomial equations or be used as a low-noise millivoltmeter.
Scanning speed is programmable up to a maximum of 1 kHz, independent of the number of
channels being scanned. This combination of filtering and scanning speed provides the EX1048
with the low noise performance required for sensitive applications as well as the speed necessary
to measure fast, fine-gauge thermocouples.
For highest accuracy and stability, the EX1048 provides an embedded isothermal input section
that is monitored by twelve precision thermistors, one for every four thermocouple channels.
Moreover, it features an internal calibration source that can be used to self-calibrate the unit upon
command. This extends the unit's high accuracy over a wide ambient temperature range. For
maximum utility, detailed temperature accuracy specifications are provided over an ambient
operating range of 15 °C to 35 °C, indicating accuracy limits with and without the use of selfcalibration.
The EX1048 VXI Technology 48-Channel, Precision Thermocouple Instrument may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
