178 REFERENCE MEASURING INSTRUMENT Data measurement at several sites using the laptop/pc The measurement system The simultaneous measurement of data at several sites is carried out by the "slave" loggers. PC insert card The slave loggers are connected directly (without control unit) to the PC insert card (PCMCIA) for the laptop/pc. Data is measured online using the laptop/pc or the loggers save the data independently via a freely definable measurement program. The logger has an internal memory for up to 250,000 readings and is also capable of logging without laptop/pc. The measurement data can be analysed at a later stage in the laptop/pc. Testo data bus Communication between PC insert card and loggers is enabled by the Testo data bus. Using the Testo data bus, you have the option of operating loggers at different sites. Distances of up to several hundred metres pose no problem for the Testo data bus. Power box The power box is used to supply power to the Testo data bus thus increasing the operating life in the field. Advantage: A convenient and clear presentation of the readings from all of the loggers connected in one view is possible when measuring online with the PC insert card.

The measuring range of the Pitot tube depends on the differential probe used. The new 100 Pa probe can therefore be used for the exact measurement of the flow speed from approx. 1 to 12. The Pitot tube yields optimum results in the higher velocity range. An additional criterion when selecting the correct velocity probe is the temperature. Thermal sensors can normally be used at up to approx. +70. Special design vane probes can be used to maximum +350. Pitot tubes are used for temperatures above +350.
