Pyrometer CellaCast PA

Jan. 21, 2017

KELLER's pyrometer CellaCast PA80 is specially designed to measure the temperature of liquid metal in the runner of a blast furnace or cupola furnace while the PA 83 model is designed to measure the temperature of liquid metal poured from a foundry ladle or discharged from a bottom pour ladle.

The PA80 features a round target spot for steady targets, while the PA83 features a rectangular target area for moving targets (moving side-to-side).  As long as the target fills 1/3 of the rectangular area, the PA83 is able to produce good, repeatable temperature data.

Both models are available with different optics, for a range of viewing distances.  Hand-held versions are also available.
