Enabling greater control of production processes, the m&h RWP20.50-TP temperature probe measures part temperature in seconds, both before and during machining.

The m&h RWP20.50 drives high production quality by ensuring that workpieces are only machined when within the defined temperature parameters. Detecting longer wave lengths than infrared, the radio wave probe is ideal for use on large machining centres and 5-axis machines. 

m&h RWP20.50 probes are characterised by high measurement reliability, using the SCS (Self-Channel-Select) technology of the microprocessor-controlled receiver to continuously check surroundings and block any interfering signals from other radio wave sources. MDR (Multi Data Rate) technology in the 2.4 GHz range offers fast transmission of high data rates and large data sets.  

Offering high flexibility, the bidirectional m&h RWP20.50 is adaptable to changing application requirements; as a modular system, various measuring units, extension and cross-probes can be used.
