The Rota-Sonde TS5500 measures the position of a hot product (steel, copper, brass, other alloys) within its field of view and provides an output which is proportional to the angular position of the product within that field.
The Rota-Sonde TS5500 is a scanning measuring sensor, sensitive to infrared radiation emitted by hot products with a minimum temperature as low as 250 °C (480 °F).
