Description Specifications Literature Description The Air Velocity Transducer 8475-12 (omnidirectional) is ideal in research and development labs, manufacturing processes, and other applications for both temporary and permanent installations for air velocity measurement. Model 8475-12 provides a linear signal output due to on-board electronics and calibration curves. This linear signal is sent out as either a current (mA) or a voltage (V) signal, allowing output to a variety of data loggers or data acquisition systems. In addition you have the ability to change the current and voltage output ranges easily in less than five minutes.Included Items:Probe attached to 16.4-ft (5-m) cable connected to control module Protective sleeveCompression fittings for mounting in duct workTwo holding clips to mount probe to parallel surfaceOperation and service manualNIST calibration certificate State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
