Definitions

  • the present invention relates to a method for fast, facile and accurate method is significantly increases when a greater number of components is to be applied and fixed within the thermometer tip, and as much as the accuracy of the relative spatial positioning of said components is important (such as in heat-flux-sensitive thermometers i.e., thermometers which calculate the temperature of a heat source without really measuring it, but by swiftly calculating it according to the differences between temperature data supplied to a calculation means from two apart heat sensors having different distances from the measured heat source).
  • the present invention relates to a method for a fast, facile and accurate placement and fixation of heat sensors or other components requiring a very accurate spatial positioning relatively to each other within the tip of a thermometer.
  • the present invention further relates to a thermometer produced according to the said method.
  • thermometers Up to date, electronic components are placed and fixed within the tip of electronic thermometers as separate free elements and are being wired to the main electronic circuit of the thermometer by means of separate wires.
  • the components are firstly have to be placed, then adhered to the interior of the thermometer tip using adhesive materials naturally requiring a predetermined hardening time, and then to be wired to the electronic circuit by soldering.
  • This is a relatively long and complicated process by which the efficiency of the production line is significantly decreased.
  • the problem is worsened as the number of components to be place within the thermometer tip grows, and as much as the accuracy of their relative spatial positioning is important, which is the situation with heat-flux-sensitive thermometers.
  • thermometers The accuracy of heat-flux-sensitive thermometers depends essentially on the accurate spatial positioning of the heat sensors relatively to each other. This is since the heat flux is calculated according to the temperature difference between the two sensors, which depends on the tiny gap between the sensors through which crosses the heat coming out of the measured heat source. In other words, the two sensors need to be located along the same axis, because heat flux must be defined along a well defined axis.
  • thermometer tip usually has relatively small dimensions, and the thermometer probe is relatively thin (i.e. having a small cross-section diameter), such that the placement and fixation of the heat sensors and their associate electrical connections is very difficult, especially in terms of mass-production.
  • the heat sensors (and other optional components such as associate resistors using as heaters) must be placed accurately in the required spatial position relatively to each other within the probe tiny tip.
  • the wiring of the said components through the relatively thin probe to the main electronic circuitry is also a relatively complicated matter, wherein up to six different wires should be passed through the casing and be connected at the one end to a tiny electrical component, and at the other end to the main electronics circuit board. Thus, a fast facile and accurate method for the production of thermometers is essentially required.
