A monitoring device for a milk collection tank with cooling system has a cooling switch (5-10) and a temperature switch (5-10). The cooling switch includes a timer circuit (7) and is connected to a temperature sensor (1) for tank temperature. It is designed to trigger an alarm if tank temperature has not fallen below a first temperature value within a first time interval from cooling switch activation when milk is poured in the tank. The temperature switch is also connected to the temperature sensor and is designed to be activated when tank temperature has fallen below the first temperature value within the first time interval. After activation, it triggers an alarm if tank temperature exceeds a second temperature value. A start switch (5-10) is designed to trigger an alarm if the cooling system is not activated within a second time interval from when milk is first poured in the tank. A washer switch (5-10) is designed to trigger an alarm if after the tank is emptied and the washer switch is activated, tank temperature has not reached a third temperature value.<IMAGE> |
