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.

• System Configuration
• Application Software
• Accurate time stamping
• Choose the packaging that suits your application
• Easy calibration

Or, add NetDAQ units directly to your company's network. Sharing the network cabling and hardware that's already installed saves you time and expense. And, if you wish, all the users on your network have an easy way to access the data you're collecting (see fig. 2).

A third configuration option is to add an isolated NetDAQ system to your company's network. This method isolates your data acquisition application from your company's network while still providing the advantages of multi-user viewing. High-speed applications won't be slowed down by network operations, and critical applications are completely protected from network failure (see fig. 3).

High-speed communication makes it easier to get results. No matter how you set up your data collection system, high-speed networked communication offers you a number of benefits. It gives you the ability to implement distributed applications with NetDAQ units in multiple locations. In these applications, multiple PC users can monitor data, in real time, as it is collected. Support for up to 3,000 readings per second (rps) from multiple instruments keeps throughput high. And you're ensured of highly reliable results, even over long distances. 

Choose the level of performance you need

Because every application is different, we offer a selection of accuracies and measurement rates to match your application needs. The 2640A offers 0.01% V dc - 0.3ºC TC accuracy and 18 bit resolution, scanning 6 - 100 channels per second. The 2645A can scan at 48 to 1000 channels per second with 16 bit resolution and 0.01% V dc - 0.6ºC TC accuracy.

All models offer a totalizer input channel which counts up to 4,294,967,295 "on/off" events. This channel is continuously sampled and is recorded with each scan of the other input channels.

Each analog and calculated channel has two user-defined alarm limits which can be independently configured as high, low, or off, and assigned to one of the eight digital I/O lines which can initiate action based on alarm conditions. Or these digital I/O lines can be used independently as inputs for contact closures, switches, or TTL levels.

The Universal Input Module makes configuration a snap

The 2640A NetDAQ can measure up to 300V at up to 100 rps. The 2645A is the first instrument of its type capable of directly measuring multiple inputs of up to 50V at 1000 readings per second. With Mx+B scaling you can convert a wide range of signals (0-10V or 4-20 mA) into standard engineering units.

Using Fluke's patented technology, thermocouple reference junction compensation occurs automatically, by sensing the temperature of the input module's isothermal block. Excellent isothermal performance is achieved by thick copper layers embedded just beneath connection points, and an enclosure that protects inputs from changing environmental conditions. And strain relief protects sensor wires from accidental disconnection.

For calibration, or use in another application, you can leave your field connections set up at your site and merely plug and unplug the module when you want to move the NetDAQ unit.

If you need your NetDAQ close at hand but out of the way, either unit can be permanently mounted on a wall, or in a rack or cabinet with optional mounting accessories.
