Monitoring unit and monitoring procedure

Abstract

Monitoring unit for a temperature control system (2) for a mold (3) and / or a forming machine (4), wherein the monitoring unit (1) includes an input module (5) and a processor (6), and wherein the input module (5) is configured to receive a first input, which represents a thermodynamic quantity, in particular a temperature, and / or a composition of a temperature control medium, and to receive a second input, which represents a pressure of the temperature control medium, wherein the processor (6) is configured to compare the minimum pressure with the vapor pressure and to generate an output signal if the minimum pressure is lower than the vapor pressure and / or lower than the vapor pressure plus a defined offset.
