The E type thermocouple senor is a high-precision temperature sensor based on the Seebeck Effect, consisting of a nickel chromium alloy (Chromel, positive electrode) and a copper nickel alloy (Constantan, negative electrode). It is known for its wide temperature measurement range, high sensitivity, and excellent stability, and is widely used in industry, scientific research, and temperature monitoring in extreme environments.
S type thermocouple senor is an internationally recognized precious metal thermocouple, consisting of platinum rhodium alloy (platinum 90%, rhodium 10%) as the positive electrode (SP) and pure platinum as the negative electrode (SN). Due to its excellent high temperature resistance, high precision, and long-term stability, it is widely used in industrial high-temperature measurement, scientific research experiments, and precision instrument fields, especially suitable for oxidizing and inert atmosphere environments.
T type thermocouple senor is a temperature sensor designed based on the Seebeck Effect principle, consisting of two different metal conductors (pure copper for the positive electrode and copper nickel alloy for the negative electrode, i.e. constantan). It has the characteristics of high stability and excellent low-temperature measurement accuracy. As one of the internationally standardized thermocouple types (compliant with IEC 584 standard), it is widely used in medium and low temperature measurement scenarios in scientific research, industry, medical and other fields.
J type thermocouple senor is a temperature sensor based on the principle of thermoelectric effect, consisting of two conductor materials: iron (Fe) and copper nickel alloy (CuNi). Its working temperature range is from 0 ° C to 750 ° C (up to 1000 ° C in a short period of time), and it has the characteristics of low cost, high sensitivity, and good stability. It is widely used in temperature measurement and control in industries, scientific research, energy and other fields.
Adhesive thermocouple is a sensor used to measure the surface temperature of objects, widely used in industries, scientific research, medical and other fields. It operates based on the thermoelectric effect, using thin sheets made of two different metal materials. One end is in contact with the object being measured to sense temperature, while the other end is connected to a measuring instrument to convert temperature into a voltage signal for measurement.
PT100 thermocouple is a temperature sensor based on the principle of thermal resistance, widely used for measuring the surface and internal temperature of metal equipment, as well as for measuring the temperature of bearing shells and other specific occasions. The "PT" in its name represents platinum resistance, and "100" indicates that the resistance value of the sensor at 0 ℃ is 100 ohms.
