Temperature Probe RWTP20.44

RWTP20.44 - fully automatic part temperature measurement at any stage of the machining process (patented)!

The temperature probe RWTP20.44 is intended for use on large machining centres and 5-axis machines when infrared transmission is not sufficient. It acquires, fully automatically, the part temperature before and during the machining (patented). This enables improved control of the production process and tuning of machining parameters during ongoing production. Temperature-dependent parameters can thus be determined with certainty before the part is taken to the next machining step with a tolerance specification, ensuring a uniformly high manufacturing quality
