Apparatus for determining the temperature of a medium
View Patent ↗An apparatus for determining the temperature of a medium, in particular of a foodstuff, including a wireless transmitter, a temperature sensor, and a reception and evaluation means which is provided outside the transmitter. In order to make the apparatus more universally usable, and in order to allow a more precise determination of the temperature, the transmitter and the temperature sensor are configured as a mobile unit for direct temperature measurement in or on the medium, and the reception and evaluation means is arranged outside the medium.
1. An apparatus for determining the temperature of a liquid medium, comprising a wireless transmitter, a temperature sensor, a reception and evaluation means which is provided outside the transmitter, the transmitter and the temperature sensor are configured as a mobile unit for direct temperature measurement in the liquid medium, and that the reception and evaluation means is arranged outside the liquid medium, wherein the mobile unit includes a floating body for holding the temperature sensor at a predetermined depth in the liquid medium.
2. An apparatus according to claim 1 , wherein the mobile unit further includes a sensor body which can be attached to a solid medium.
3. An apparatus according to claim 2 , wherein the sensor body is configured as a spear for insertion in the solid medium.
4. An apparatus according to claim 1 , wherein the transmitter is an RFID tag, and the reception and evaluation means comprises an RFID reader and evaluator with integrated power supply.
5. An apparatus according to claim 1 , wherein the reception and evaluation means includes an alarm device.
6. An apparatus according to claim 1 , wherein the reception and evaluation means includes an indicating device.
7. An apparatus according to claim 1 , wherein the reception and evaluation means includes a manual input unit.
8. An apparatus according to claim 1 , wherein the reception and evaluation means includes a timer.
9. An apparatus according to claim 1 , wherein the reception and evaluation means includes a control unit for controlling a heating source.
10. An apparatus according to claim 1 , wherein the medium is a foodstuff.
11. A float comprising a temperature sensor and an RFID tag, wherein the float is configured such as to hold the temperature sensor at a predetermined depth in a liquid medium.
