Humidity sensor

Cavity sensors for die casting processes which is built in the vacuum supply for the die casting mold and records humidity changes during the injection process.

Residual water in the mold after the process can result in substantive quality losses. With a specific LFS humidity sensor, the remaining humidity in the mold can be measured during evacuation. Since a mold evacuation is performed within a short period (within a couple of seconds), the use of fast and modern humidity sensors is required. Humidity is indicated in percent and shown graphically (Fig. 1).
