Fluke 26240A/2645A NetDAQ Networked Data Acquisition Unit

Fluke 26240A/2645A NetDAQ Networked Data Acquisition Unit

Product Documentation

Description

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.

Features at a glance:

  • Data acquisition, up to 1,000 readings per second
  • 20 analog input channels expandable up to 400 channels
  • Extensive optional plotting and trending capabilities
  • Optional wall, cabinet, or rack mounting
  • May be connected to Ethernet networks
  • Replaces chart recorders

NetDAQ systems are modular and expandable up to 400 channels. With the 20-channel units as building blocks, you can buy the number of channels you need for your application. Later, add units if you need them.

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.

NetDAQ’s Universal Input Module lets you easily measure just about any electrical or physical parameter without changing hardware or adding external signal conditioning. Any combination of dc voltage, ac voltage, thermocouples, current, RTD, resistance (2- or 4-wire), or frequency measurement can be connected directly to the input module. Fluke’s proprietary signal conditioning capability is built directly into the NetDAQ unit, thus eliminating the need to purchase external conditioning modules.

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.
