Also, where do you put the temperature probe in a turkey? Slip your meat thermometer into the thickest part of the turkey thigh, pricking the bird just above the crease between the thigh and the place where the turkey breast begins, and driving it into the thigh meat. When the counter reads 165 degrees, your turkey is ready.
Besides,How does a fiber optic GaAs temperature probe work?
fiber–optictemperatureprobe must be in contact with the material it is measuring. The more intimate the contact, the faster the crystal will respond to the temperature changes. A tiny crystal of GaAs with a dielectric mirror is bonded to one end of a cleaved optical fiber (see Figure 3). PTFE is then used to cover the entire assembly, serving as an excellent buffer.
Similarly,How does a thermocouple probe work in a gas tank?
Threaded Thermocouple Probe Transmitters for Liquids and Gases Send temperature readings from tanks, containers, and pipes to devices such as remote displays and programmable logic controllers (PLCs) without the hassle of direct wiring.

How does a meat thermometer work and how does it work?
The needle will turn as the temperature goes up in the probe’s temperature sensing area. The drawback of this thermometer is that the temperature sensing area of the probe is over 2 inches and displays the average temperature of this area. So for any meat that is thinner than this, you won’t get an accurate reading.

Why do we use the four probe method instead of the two?
The reason using four probes instead of two by having force and sense probes is to eliminate contact resistance and increase accuracy. If the current used is not constant and has a time varying components, the parasitic probe capacitance and inductance would affect the measurement hence reduce the accuracy of the measurement.
How big of a probe do you need for a meat thermometer?
You’re looking to find the lowest internal temperature—that’s the most accurate temperature for the core of the meat. Most thermometers require you to insert the probe at least 1/2 inch into the meat (only 1/8 inch for Thermoworks models), but if the meat is thicker than an inch, you’ll probably want to go deeper than that to reach the very center.
How do you find the lowest temperature for meat?
The best way to find the lowest temperature of whatever you’re cooking is to insert the thermometer not only into the thickest part but as far as the meat thermometer will go into the food. Then you want to slowly pull the meat thermometer through the food while trying to find the lowest temperature.
What causes a thermometer to display an inaccurate temperature?
You will need to replace the probe for your unit. 10-20° Inaccuracy: This is usually a result of moisture seeping into the probe and throwing off the temperature detected by the device within that reads temperature.

Why does a plasma have a higher electron current?
Although a plasma is electrically neu- tral, and the electron and ion densities are very nearly equal, a floating probe will tend initially to draw a higher electron current because the electrons reach the probe faster than the more massive ions.
How are ion and electron densities in plasma?
Plasma is then a collection of the various charged particles that are free to move in response to fields they generate or fields that are applied to the collection and, on the average, is almost electrically neutral. This means that the ion and electron densities are nearly equal, nine, a condition commonly termed “quasi-neutrality.”

Finally, if all of that seems too complicated, provide a hole in your end-bells/bearing support and place it your thermocouple.
What happens to the current as voltage decreases?
According to the graph as voltage decreases, current increases. The only way I can explain it using the equation V=e-rI is that for some reason internal resistance r increases and as eloctromotive force stays the same, this means decrease in voltage V so both sides equal each other again. But wait!
