  • Why spray sensors
  • Production
    • Accuraspray 4.0 – Thermal SprayThe Accuraspray 4.0 is an in-line thermal spray sensor that measures the spray plume temperature, velocity, dimension, orientation, intensity and stability. One sensor for all spray processes: APS, HVOF, Wire-Arc, Flame Spray, HVAF, SPS, VPS, LPPS, PTWA.
    • Accuraspray CS – Cold SprayThe Accuraspray CS is a production-friendly cold spray sensor that measures in-flight particle velocity and feed rate.
    • Shotmeter 4.0 – Shot peeningThe Shotmeter 4.0 is an in-line shot peening sensor that measures in-flight particle velocity. This is an easy-to-use sensor to monitor daily, equipment status, quality control, process development, and setup transfer.
  • Research
    • DPV evolutionThe DPV evolution is the industry’s standard for understanding the details of in-flight particle dynamics. It measures the velocity, temperature and size for individual particle.
