powiedziano mi, że jest albo spirala albo pręt i to trzeba jako drugie zaznaczyć w nazwie

W takim termometrze spirala.... Nie spirala, ale pręt.

Solids also change their volume as temperature changes. When solids are organized in long rods,
that change is best manifested in the length dimension. Different solids have different
temperature expansion properties, and if we look at the response of several rods made of
different metals we will see that each rod expands by its own characteristic length when the
temperature changes by, say, 1 degree C. When rods of two metals with different temperature
expansion properties are fused or stuck together, a change in temperature will distort them, i.e.,
cause a change in their configuration in relation to a reference point. Mechanical bimetal
thermometers are based on this principle: differential expansion causes a bimetal shaft to twist
and move a pointer on a scale. Bimetal thermometers are often used for temperature higher than
boiling point (e.g., in oven thermometers or in “meat” or “candy” thermometers). They are also
the basis for many thermostats in high-temperature equipment. This type of thermometer is
seldom used for environmental monitoring at the range of ambient temperatures, therefore it has
not been included in the Method Menu abov

I to jest właśnie kontekst.

Jak na złość to tylko pozycja w ofercie na instalację pomiarową do piwa (ciśnienie, temp., natężenie przepływu, objętość, stężenie, poziom alkoholu, gęstość brzeczki podstawowej)

Obawiam się, że bez szerokiego kontekstu trudno będzie pomóc.
