Round cartridge heaters are heating elements designed for industrial applications where localized and controlled heating is required. They are cylindrical in shape, typically made of stainless steel, and consist of a heating wire embedded within a ceramic or mineral insulation material.
Specifications
- Construction: Round cartridge heaters are composed of a stainless steel sheath that encloses the heating element. The sheath provides mechanical protection and prevents contact between the heating wire and the surrounding environment. The sheath is often corrosion-resistant to withstand harsh operating conditions.
- Insulation: The heating wire is embedded within a ceramic or mineral insulation material. The insulation serves two purposes: it electrically isolates the heating wire from the sheath, preventing short circuits, and it helps retain and direct the heat generated by the wire towards the intended target.
- Connection: Cartridge heaters have two lead wires that extend from one end of the heater for electrical connection. These leads are usually made of high-temperature-resistant materials and can be connected to a power source using appropriate connectors or terminals.
