Kontaktilämpömittaukset

Kontaktilämpömittaukset refers to temperature measurement methods that rely on direct physical contact between a temperature sensor and the object or substance whose temperature is being measured. This is in contrast to non-contact methods like infrared thermometry. The sensor must be in thermal equilibrium with the object for an accurate reading.

Common types of contact thermometers include mercury-in-glass thermometers, bimetallic strip thermometers, and thermistors. Thermocouples are also widely used for contact temperature measurements, especially in industrial applications. The choice of contact thermometer depends on factors such as the desired temperature range, accuracy requirements, and the nature of the substance being measured.

Proper contact is crucial for accurate readings. Poor contact can lead to heat loss or gain from the surroundings, resulting in erroneous measurements. Therefore, ensuring good thermal coupling, such as by applying thermal paste or ensuring a snug fit, is important. Contact thermometry is a fundamental technique used in a wide array of fields, including science, industry, medicine, and everyday life.
