Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes.

Thermal cutoffs and thermal protectors are nonresetting, thermally sensitive devices designed to protect domestic electrical appliances and industrial equipment from fire.

Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level.

Calorimeters and thermal analyzers contain a heat source that can deliver a heat flux, at a distinct temperature, into a sample, and a temperature-measuring device that can read the resultant change in temperature

Gas flow switches and liquid flow switches, velocity, are used to measure the flow or quantity of a moving fluid in terms of velocity, such as feet per minute

Temperature instruments use contact or noncontact methods to measure temperature.
