Abstract
A temperature measuring device and method of using it are disclosed herein. A temperature sensing strip is disposed within a housing used for agitating a material, the temperature of which is to be measured. The strip has a series of sensor dots containing liquid crystal material.
Claims11
A device for measuring the temperature of a material, comprising:
- a rigid elongated housing for agitating the material;
- a temperature sensing strip disposed within said housing so that a portion of said housing engages the material to measure its temperature;
- said strip having a series of adjacent sensor dots, each having liquid crystal material contained therein for changing colors with changes in the temperature of the material to provide a visible temperature measurement readout;
- and
- wherein said sensor dots are each spaced from the interior of said housing to insulate the dots from the ambient environment so that the temperature readout is relatively stable.
2 more elements
A method of using a device for measuring the temperature of a material, comprising:
- using the device which is elongated and includes temperature sensors at substantially one end thereof;
- inserting the device into the material;
- moving the device to agitate the material;
- withdrawing the device from the material to permit viewing the temperature sensors for providing an indication of the temperature of the material;
- and
- re-inserting the device into the material to enable a further temperature reading to be taken for monitoring temperature changes of the material.
3 more elements
A method of making a device for measuring the temperature of a material, comprising:
- using an elongated, substantially rigid housing;
- inserting a temperature sensing strip having temperature sensors disposed thereon into the hollow interior of the housing and disposing the temperature sensors of the strip at the bottom portion of the housing;
- and
- sealing the housing to retain the strip therewithin in a liquid tight manner.
