The EX10xxA family of products provides a total of 48-channels, with an exception of RX10xx
products which has 32-channels, of high-performance thermocouple and/or voltage measurement in
a single instrument. This family includes the EX1000A, EX1000A-TC, EX1016A, EX1032A,
EX1048A, EX1000A-51C and RX1032. The last two digits of the model name indicate the number
of thermocouple channels/voltage channels available on the model. For example, the EX1016A has
sixteen thermocouple channels and thirty-two voltage channels. Its combination of measurement
performance and integrity, configuration flexibility, package density, and network connectivity
make it the most powerful, yet easy-to-use, instrument of its kind. The EX10xxA is a complete, self-
contained temperature measurement system that communicates over Ethernet. Unlike other data
acquisition offerings in its class, the EX10xxA 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.
EX1000A-51C is the enhanced version of the EX10xxA family of products, has 51 Voltage
Channels and has additional features such as additional sensors to measure internal box temperature
and additional API’s provided to read UTC offset & warmup time.
RX10xx is the rugged version of the EX10xxA family of products, has 32 Channels and most
importantly provides the user with the flexibility to place this instrument even in extreme conditions
and directly in the test cells because of its rugged build.
EX1044 is the customized version of the EX10xxA family of products, has 44 TC Channels and 2
channels for voltage/current respectively. This provides thermal labs customers the ability to place
instrumentation directly in the thermal test labs. The EX10xx product has already demonstrated
some of the highest accuracy in the market for Thermocouple measurements and the EX1044 will
continue to provide as good or better accuracy for gas turbine test cell users trying to improve engine
efficiency by better understanding temperature effects on the DUT.
The EX10xxA 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 EX10xxA, 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 transducer detection
system.
The EX10xxA 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 EX10xxA can be programmed with
