CellaCast PA 83 was specially designed to measure the temperature of liquid metal poured from a foundry ladle or discharged from a bottompour ladle.
Features:
- Temperature range: 650 – 1700 °C
- Maintenance-free, wear-free system measures the pour stream temperature at casting machines
- Optics with rectangular target spot ensures reliable temperature data even when pour stream position varies
- ATD function automatically records a temperature for each cast object
- Dual wavelength technique yields accurate readings despite smoke or dust in the sight path
- Sighting options: through-the-lens sighting or video camera
