上記、温度測定の技術に関しての面白そうな動画があったのでリスニングしてみた。
赤文字ははっきり聞き取れない部分。
青文字はそのように聞き取れるが、文法的にしっくりいかない部分。

Many people think that temperature measurement is simple. All you need are a few micrograms of platinum or thermo-coupled material and heaprest. You can measure the correct temperature. But, thermometer doesn't necessary equate to thermometer, nor does temperature equate to temperature.

The sensor, the heart of every temperature measurement point. For a long life, it must be very precisely built and well protected in its application. Always up-to-date, and continuously monitored. That is what we, the people for process automation, take care of. We make sure that it always delivers the correct temperature.

Basically, the sensor is only a resistor, whose value changes in line with the temperature. But how does it show us the exact value. For example, a hundred ohm at 0 degree celsius. First of all, pure platinum, a hundred times thinner than the human hair, is placed on to a highly pure ceramic substrate.

The so-called wafers are produced in dust-free clean rooms. Using processes from semiconductor technology, numerous small temperature dependent resistors are produced on the wafers. A highly precise laser trims them to the exact resistance value. In this case, a hundred ohm at 0 degree celsius.
heaprest か heaplest という単語は初めて聞いた。 検索してもそれらしいものは見つからず。
platinum(白金）や thermo-coulpled materialでの温度測定というのは関連図書で出てくる。
