A thermocouple is a temperature sensor made from two conductors of dissimilar metals joined at one end, which generates a small voltage proportional to the temperature difference between the measuring junction and the reference junction.
RTD is a temperature sensor that measures temperature by the change in
electrical resistance of platinum, which has a nominal resistance of 100 ohms at 0°C.
A mica band heater is an electric heating element designed to clamp around cylindrical surfaces such as barrels, pipes, and nozzles to deliver uniform heat through conduction.
A ceramic band heater is a high-temperature electric heating element designed to wrap around cylindrical surfaces such as barrels, pipes, and nozzles to provide uniform, controlled heat.
A cartridge heating element (or cartridge heater) is a tube-shaped, heavy-duty industrial electric heating component designed primarily for insertion into drilled metal holes to provide localized, high-density contact heating.
Incoloy heating elements are electric heating components encased in an outer sheath made from Incoloy a high-performance superalloy composed primarily of nickel, iron, and chromium
Ceramic withdrawables (often referred to as ceramic withdrawable heating elements or bobbin heaters) are industrial electric heating units designed for easy removal and replacement.
In industrial and chemical processing, an Over-The-Side immersion heater is an electric heating unit designed to be installed through the open top of a tank or vessel rather than through drilled side walls.
