Abstract

A device for measuring a temperature, comprising a circular printed circuit board comprising a circular inner material comprising a controller, a power supply and a transmitter, and an outer material which is arranged radially around the circular inner material; and at least one thermal sensor which is arranged at the outer material of the circular printed circuit board.

Claims (12)

1 . A device for measuring a temperature, comprising

a circular printed circuit board comprising a circular inner material comprising a controller, a power supply and a transmitter, and an outer material which is arranged radially around the circular inner material, wherein the outer material comprises a plurality of tongues which are radially arranged around the inner material; and

a plurality of thermal sensors surrounding an outer circumference of the circuit board, wherein each tongue of the plurality of tongues comprises at least one thermal sensor which is arranged on the upper surface of the respective tongue of the plurality of tongues.

2 . The device of claim 1 , wherein a double T-shaped bridge is arranged in a tongue for thermally connecting the lower surface of the tongue to the upper surface of the tongue, and wherein each T-shaped bridge comprises at least one sensor which is arranged on the upper surface of the double T-shaped bridge.

3 . The device of claim 1 , wherein the power supply is rechargeable.

4 . The device of claim 1 , wherein the power supply is a battery.

5 . The device of claim 1 , wherein the transmitter is a wireless transmitter.

6 . The device of claim 1 , wherein the bridge is made of metal.

7 . The device of claim 1 , wherein the outer material is thinner than the inner material.

8 . The device of claim 7 , wherein the outer material has a thickness of ≤0.2 mm and the inner material has a thickness in the range of 1 to 2 mm.

9 . The device of claim 1 , wherein the inner material has a centrally arranged hole.

10 . The device of claim 9 , wherein the hole has recesses for receiving corresponding structures of an axis.
