The electric heater combines aluminum alloy and silicone rubber through a special process, and uses imported electric heating wires internally, which has the characteristics of flat and ultra-thin. This series of heaters has good heating effect, and the heating body of the product uses nickel chromium alloy wires and heating blocks, with high thermal efficiency and long service life.

Moisture-proof silicone rubber and alkali free glass fiber double insulation make the insulation performance of the heater more reliable. Aluminum plates assist in heat dissipation, improving the thermal efficiency of the heater and extending its service life. Easy installation. Cabinet heaters can be used for heating and insulation of various cabinets and boxes. For example, switch cabinets, communication cabinets, lighting cabinets, anti condensation boxes, computer cabinets, etc.

Firstly, let's introduce thermocouples. Thermocouples are the most widely used temperature devices in temperature measurement. Their main characteristics are wide temperature measurement range, stable performance, simple structure, good dynamic response, and the ability to remotely transmit 4-20mA electrical signals, making it easy for automatic control and centralized control. The temperature measurement principle of thermocouples is based on the thermoelectric effect. When two different conductors or semiconductors are connected into a closed circuit, when the temperatures at the two contacts are different, a thermal electric potential will be generated in the circuit. This phenomenon is called the thermoelectric effect, also known as the Seebeck effect.

Secondly, we will introduce the thermal resistance in electric heaters. Although thermoelectric resistance is widely used in industry, its application is limited due to its temperature measurement range. The temperature measurement principle of thermoelectric resistance is based on the characteristic that the resistance value of a conductor or semiconductor changes with temperature. It has many advantages, such as the ability to transmit electrical signals remotely, high sensitivity, strong stability, good interchangeability, and accuracy. However, it requires power excitation and cannot measure temperature changes instantaneously. Industrial thermistors generally use Pt100, Pt10, Cu50, Cu100. The temperature measurement range of platinum thermistors is generally -200 to 800 degrees Celsius, while copper thermistors are -40 to 140 degrees Celsius. Thermal resistors have the same distinguishing type as thermocouples, but they do not require compensating wires and are cheaper than thermocouples.
