Stratronics melt pool sensors heat flow sensorsThermaViz® is a complete system that delivers real-time, true temperature images and measurements with its melt pool and global heat flow sensors. The Melt Pool Sensor provides precise temperature measurement using 2-wavelength (λ) pyrometry technology and high resolution thermal images. The 2λ approach effectively eliminates sensitivity to emissivity; where as other 1λ technologies require the emissivity to be estimated and set.

A broad range of thermal and dimensional aspects of the melt pool are measured in real-time; peak and average temperature, solidification contour and dimensions (area, length and width), heating and cooling rates.

The DMLS ThermaViz Sensor has specific key enhancements over the Laser Metal Deposition Sensor to achieve the key requirements of capturing and resolving the smaller and higher speed melt pool in this advanced dynamic process. The Global Heat Flow (GHF) Sensor provides measurements of the deposit side view or the melt pool in an extended lower temperature range. Real temperature measurements are obtained from the GHF Sensor when correlated simultaneously to the Melt Pool Sensor data. All sensors are packaged for harsh environments.
