The invention relates to a device (1) for measuring moisture in pressure molds (24), the mold cavity (25) of which is connected to a venting device (28) by a vent line (31). The device (1) is connectable to the vent line (31) and comprises a sensor arrangement (S) by means of which the measurable moisture in the gases extracted from the mold cavity (25) is measurable. The sensor arrangement (S) comprises at least one transmitter (7) emitting electromagnetic radiation. On the basis of the measured values found during the venting, it is possible to determine whether the amount of the mixture of water and the separating means to be injected into the mold cavity (25) is to be changed before the actual casting process. |
