RF-linked dataacquisition eliminatesthe obstacles togathering data

With the Fluke Wireless Logger,you can collect and transmitdata via a secure RF link fromvirtually any location—no matterhow inaccessible—without theexpense or hassle of runningcable long distances.

Spread spectrumRF technology clearsthe way

Unlike traditional narrow band RFtransmission that is susceptible toelectromagnetic interference, thespread spectrum technology usedin the Wireless Logger is ideal inareas where narrow band equip-ment fails. It was developed formilitary communications systemsrequiring exceptional immunity toelectromagnetic interference andhigh data transmission integrity.This means you won’t have toworry about motors, solenoids,walkie-talkies, and other sourcesof severe electrical interferenceinterrupting your transmissions.It transmits up to 120 metersthrough walls and floors, or up to300 meters in line-of-sight appli-cations using the modem.

This technology also allowsthe Wireless Logger to coexistwith other electronic equipment.Its power output is lower thancellular phones. The spreadingtechniques and frequency dwelltimes used by the WirelessLogger modems produce an

effective peak power at anyfrequency that is lower thanequivalent narrow band trans-mission—too low to disrupt orinterfere with other electronicinstrumentation. And, it complieswith FCC part 15C and does notrequire an FCC site license. Theoptional 2.4 GHz modem is ETSIcertified for operation in mostEuropean and many othercountries.

Saves on hazardous dutyThe Wireless Logger thrives ontough jobs that would put peopleat risk. Whether it’s placed atthe top of a smokestack, or sur-rounded by toxic materials, highvoltage, or exhaust fumes, theFluke Wireless Logger is quick toset up and can take the heat.

Fault tolerance preventsdata lossEach Wireless Logger satellitecan store more than 2000 scansin its nonvolatile buffer. If your PCgoes down during data acquisi-tion, the Wireless Logger satellitecontinues to collect measure-ments. When your PC comes backon line, the data collected in theinterim can be transferred to yourdata file automatically.

The Wireless Logger satelliteconsists of a Hydra Data Logger(2625A) and a 2.4 GHz wirelessmodem, both housed in a pro-tective soft-sided carrying case.Built-in signal conditioningeliminates the need to addadditional components forsignal or sensor interfacing.

Back at the office, attachthe wireless base stationmodem to the RS-232 porton your PC, install WirelessLogger for Windows software,transmit your setup informa-tion and you’re ready to startcollecting data.

Fluke measurementspecificationphilosophy

The accuracy specifications forHydra and NetDAQ instrumentsare calculated conservatively sothat they include three standarddeviations from the nominalvalue—this is referred to as3-Sigma. Greater than 99.7% ofthe instruments produced willperform within the error limits.Rigorous screening and testingprocedures catch and correct thethree out of 1000 instrumentswhich could have fallen outsidetheir published specifications.Many other products use a ‘root-sum-square’ scheme, or onlyspecify the error band within onestandard deviation (1-Sigma) ofnominal. This method produces aspecification that appears to bemore accurate, but the resulting“typical” specifications correctlycharacterize only ~66% of theinstruments produced. Thismethod is kind of like knowinghow accurate “most of the instru-ments” will be. NetDAQ’s3-Sigma specifications tell youhow accurate ALL of the instru-ments will be.Note: Listed specifications are summary innature. Accuracies listed are most favorablewithin the stated range. You may obtaindetailed specifications by contacting theoffices listed on this page.
