Uncooled thermal imaging camera secures data in rigorous applications

If you can't stand the heat, get a real-time thermal imaging camera that can. Heat contains valuable data about production process efficiency and resulting product quality. However, cryogenically cooled thermal imaging cameras often can't handle continuous, unsupervised process monitoring and control, while spot sensors often provide too little information for true thermal profiling and c...

Rate/RPM/Frequency Input DPM

Tucson, Ariz. —Model 210 digital panel meter accepts input signals from magnetic pick-ups, photocells, encoders, proximity detectors, transmitters, and power lines. Its Frequency-Voltage technique converts these inputs to a 0-2 V dc for the 4.5 digit A/D. The F-V system allows frequency measurement and control without the need for specific gear ratios.
