The Type B thermocouple significantly improves high-temperature resistance and anti-interference performance. Its small size, light weight, and easy installation make it widely applicable to various temperature measurement applications.

Superior Temperature Measurement Performance

Rugged and Flexible Structural Design
SISCO B type thermocouple is widely used in applications such as industrial furnaces, heat-treating equipment, ovens, and kilns, especially where reducing or vacuum environments are present. It is also common in plastic extrusion and injection molding machines, as well as food processing and HVAC systems that operate within its moderate temperature range.

Q1: What is a thermocouple?
A1: A thermocouple is a commonly used temperature-measuring component in a temperature-measuring instrument. It directly measures the temperature and converts the temperature signal into a term electromotive force signal, which is converted into the temperature of the measured medium by an electric meter (secondary meter). The shape of various thermocouples is often very different due to the needs, but their basic structure is almost the same, usually composed of the hot electrode, insulating sleeve protection tube and junction box, etc., usually with a display instrument, recording instrument and electronic adjustment Used in conjunction with the device.
Q2: What is a K-type thermocouple used for?
A2: As a transmitter for measuring temperature, industrial K-type thermocouples are usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure the surface temperature of liquid, vapor and gaseous media and solids ranging from 0°C to 1000°C in various production processes.
Q3: How does a thermocouple work?
A3: A thermocouple is the connection of two different conductors or semiconductors into a closed circuit. When the temperature of the two junctions is different, an electromotive force will be generated in the circuit. This phenomenon is called the hot spot effect, also known as the Seebeck effect. The end directly used to measure the temperature is called the working end, and the other end is called the cold end. The cold end is directly connected to the instrumentation or supporting equipment, and the display instrument will point out the electromotive force generated by the thermocouple.
Tips: What are the Advantages of Type B Thermocouple?
Its main advantages lie in its extremely high upper temperature limit (approximately 1800℃ for short-term use, 1700℃ for long-term use) and excellent stability. It exhibits strong resistance to oxidation and volatilization at high temperatures, is not prone to degradation, and is particularly stable in oxidizing atmospheres. Since both thermoelectrodes are made of platinum-rhodium alloy, the thermoelectric potential is extremely small at room temperature, typically eliminating the need for compensating wires.
