The invention relates to a device (1) and a method for measuring moisture in diecast molds (24), whose hollow space of the mold (25) is connected through a ventilation duct (31) with a ventilation device (28). The device (1) configured in a modular manner can be connected to the ventilation duct (31) and comprises an arrangement of sensors (S), by which the humidity of gases extracted from the hollow space of the mold (25) can be measured. The sensor arrangement (S) has a transmitter (7) that emits electromagnetic radiation and a receiver (14) that detects electromagnetic radiation. Due to the measured values determined during the evacuation process, it can be determined whether the amount of a mixture of water and mold release agent, which is injected before the smelting process proper in the hollow space of the mold (25), has to be modified . |
