lämpötilabulbi

A lämpötilabulbi, often translated as a temperature bulb or sensing bulb, is a component used in various temperature measurement devices. Its primary function is to house and protect the temperature-sensitive element, such as a thermocouple, thermistor, or RTD, while also facilitating efficient heat transfer from the environment to the sensor.

The bulb's construction is typically made of materials that conduct heat well, like copper, brass, or stainless steel, to ensure a rapid and accurate reading of the surrounding temperature. The design of the bulb can vary depending on the application. Some are simple, sealed tubes, while others may feature fins or other surface enhancements to increase the surface area for better heat exchange, especially in moving fluids or gases.

In many industrial and scientific contexts, lämpötilabulbs are used in conjunction with temperature probes or sensors to measure the temperature of liquids, gases, or solids. They are found in applications ranging from HVAC systems and industrial process control to laboratory equipment and medical devices. The protective nature of the bulb also shields the delicate sensing element from mechanical damage, corrosive substances, or other environmental hazards, thereby extending the lifespan and reliability of the temperature measurement system.
