OMEGA TVS-1000-Series Air Velocity and Temperature Measurement System

The TVS-1004 and TVS-1008automatic temperature and velocityscanners are portable, 4- and8-channel hot wire anemometersystems. The TVS-1100 series arefactory expandable for up to 32 totalsensors. Fully automated, theseresearch-quality instruments takeaccurate single- or multi-pointmeasurements of air temperature,velocity and surface temperature incomplex environments, such asPCBs and electronics enclosures.When used as temperature loggers,they can measure both fluid andsolid temperatures.

The TVS-1000 series employpatented, fast response, omnidirectionalsensors, which measureboth temperature and velocity. Thispatented single-sensor technologyeliminates errors introduced as aresult of air flow being non-isothermal.Each precisely calibrated sensor isflexible and robust with a low-profileconfiguration that allows minimallyintrusive mounting throughout thepeaks and valleys created by the PCB components. Thesesystems require a PC tooperate and utilize theprovided software fordata acquisition andreporting.

The candlestick stylesensor, is a flexible,robust, base-and-stemdesign sensor that measures bothtemperature and air velocity forcharacterizing thermal conditions inelectronic systems. The candlesticksensor is narrow and low profile tominimize the disturbance of theheat flow in the test domain. Itfeatures a flexible, plastic-sleevedstem, which facilitates installationand repositioning during the testingprocess. Sensors are calibrated forlow (natural convection) and highvelocity flows. They are capable oftemperature measurements rangingfrom -30 to 150°C ±1°C. Velocitymeasurements range from 0 to 20 m/s (4,000 ft/min). Higher ranges available, contact Omega for details.The use of a single sensor to measure bothtemperature and velocity eliminateserrors that can occur when airflowis non-isothermal. Multiplecandlestick sensors can be easilyinstalled to thoroughly map asystem’s thermal and airflowconditions. Their robust natureallows for continuous repositioningand reading.
