Type TP TN TP 0.1mm Copper Constantan Thermocouple Bare Wire Type T

Introduction:

T-type thermocouple bare wire is a common temperature measurement device, widely used in industrial control and laboratory research fields. Copper-copper-nickel thermocouple (T-type thermocouple), also called copper-constantan thermocouple, is the best cheap metal thermocouple for measuring low temperatures. Its positive electrode (TP) is pure copper, and the negative electrode (TN) is a copper-nickel alloy, often called constantan. It is common with nickel-chromium-constantan constantan EN, but not with iron-constantan constantan JN, although they are both called constantan.

Copper - Copper-nickel thermocouple measuring temperature range is - 200~350°C.

The structure of the T-type thermocouple bare wire is relatively simple. It consists of two slender metal wires. One end of the two wires is connected together to form a measurement point, and the other end is connected to a temperature measurement device, such as a temperature transmitter or data sensor. Acquisition System. Typically, T-type thermocouple bare wires have smaller wire diameters to increase sensitivity and response speed.

When measuring temperature, the measuring point of the bare wire of the T-type thermocouple is exposed to the environment that needs to be monitored. Temperature changes will cause a slight potential difference between the metal wires. There is a specific relationship between this potential difference and temperature, known as the thermoelectric effect. By measuring this potential difference, the temperature of the environment can be accurately calculated.

However, it should be noted that T-type thermocouple bare wires may oxidize and corrode in high-temperature environments, so in specific applications, protective measures may be required, such as the use of protective sleeves or coatings to extend their service life.

Characteristic:

• Thermocouple material: T-type thermocouple bare wire is composed of copper (Copper) and copper-nickel alloy (Constantan). Copper is the positive electrode of the bare wire of the T-type thermocouple, and Constantan is the negative electrode.
• Temperature range: Type T thermocouple bare wire is suitable for lower temperature ranges, typically measuring temperatures from -200°C to 350°C (-328°F to 662°F).
• Linear characteristics: T-type thermocouple bare wire has good linear characteristics and can provide relatively accurate temperature measurement.
• Low drift: T-type thermocouple bare wire has low drift characteristics and can maintain relatively stable temperature measurements.
   

Advantage:

• Widely used: T-type thermocouple bare wire is widely used in industrial control and laboratory environments.
• Corrosion resistance: T-type thermocouple bare wire has good corrosion resistance and is suitable for temperature measurement in some humid and corrosive environments.
• Fast response: T-type thermocouple bare wire has fast temperature response capability and can quickly reflect temperature changes.
