Fluke 2645A NetDAQ Data Acquisition Unit
NetDAQ Data Acquisition Units give you a powerful combination
of hardware and software that's ideal for small-to-medium scale process
monitoring and test systems. They answer the escalating need for measurement,
recording, and analysis tools that enable you to improve quality, maximize
process efficiency and meet regulatory requirements. Building blocks of
20 channels can be expanded into integrated systems of up to 400 channels.
Choose between two models for speed up to 1000 rps and accuracy up to
0.01%. All NetDAQs utilize Fluke's patented Universal Input Module which
accepts any combination of analog input types for each of its 20 channels
- without the need for external signal conditioning. Simply pre-wire the
Universal Input Module to directly measure temperature, dc volts, ac volts,
resistance, 4-20 mA, and frequency. (For more information refer to the
Universal Input Module in this section.)
Distributed NetDAQ systems plug right into your existing
networks to send data directly to a PC. This saves the cost of setting
a new network and allows multiple users to simultaneously view data in
real time. A NetDAQ unit can also be used as a portable dedicated system
connected to a notebook computer for maintenance, product validation,
research, and troubleshooting applications.
