Abstract
The temperature of the milk from animals such as cows is measured during the milking process to indicate the health of an animal. An abnormal temp. may indicate infection of a teat or that the animal is on heat. This allows the veterinary surgeon to be alerted. A power supply (11) rectifies an AC supply to power a sensor (10) containing a thermistor (8). This is mounted in the common output from the four teat cups to measure the milk temperature. A differential input amplifier (13) compares the sensor output with a reference (14) and the difference signal (15) is applied to a memory circuit (16). A switch (19) resets the memory to zero. The memory output drives an oscillator (17) to flash a lamp (18) when the temperature in outside a given limit.
