Abstract
A meter for determining the temperature of a grain sample comprises two long conductors (7, 8) having temperature dependent resistance and being bent to cover a certain area, a current sensor (9,10) connected to the conductors and means for calculating the resistance of the conductive element based on the measured current and the temperature based on the calculated resistance value.
Claims5
Meter for determining temperature of a grain sample, comprising:
- at least one elongate conductive element (7,8) having a resistance dependent on the temperature and being bent in a pattern so that it covers a certain area,
- a sensor (9,10) for measuring the current flowing in the conductive element (7,8) and
- means for calculating the resistance of the conductive element based on the measured current and the temperature based on the calculated resistance value.
Dependencies are inferred from the claim text.
