Thermocouples Bare Wire R S B Type For Precision Temperature Measuring Instrument

Introduction:

Platinum-rhodium alloy thermocouple bare wire is a commonly used thermocouple temperature measurement device, which is composed of alloy wires of platinum and rhodium. According to different alloy compositions and structures, they can be divided into B-type, R-type and S-type thermocouple bare wires.

The measurement principle of these platinum-rhodium alloy thermocouple bare wires is based on the thermoelectric effect, that is, temperature changes cause a small potential difference between the alloy wires. By measuring this potential difference, the temperature of the environment can be accurately calculated. They offer good corrosion resistance and low thermocouple resistance drift, making them suitable for applications requiring high accuracy and long-term stability.

Thermocouple wire type B:

Type B thermocouple bare wire uses platinum-rhodium alloy wire (platinum 70%, rhodium 30%) and platinum-rhodium alloy wire (platinum 94%, rhodium 6%) as thermocouple materials. It has a wide temperature measurement range (usually from 0 degrees Celsius to 1820 degrees Celsius), high accuracy and stability, and is suitable for various temperature monitoring and control application scenarios.

• Temperature range: Suitable for high temperature measurements, typically measuring temperatures from 0°C to 1,820°C (32°F to 3,308°F).
• Advantages: It has good linear characteristics and stability, and is suitable for temperature measurement in high temperature environments.
• Specific parameters of interest: Thermoelectric potential output varies with temperature changes, typically at the microvolt (μV) level.
• Specific application fields: Widely used in high temperature measurement and control fields such as glass industry and ceramic industry.

Thermocouple wire type R:

Type R thermocouple bare wire uses platinum-rhodium alloy wire (87% platinum, 13% rhodium) and pure platinum wire as thermocouple materials. It has a wide high temperature measurement range (usually from 0 degrees Celsius to 1768 degrees Celsius), high accuracy and reliability, and is suitable for industrial control and scientific research applications in high temperature environments.

• Temperature range: Suitable for high temperature measurements, typically measuring temperatures from 0°C to 1,600°C (32°F to 2,912°F).
• Advantages: It has excellent linear characteristics and stability and can provide high-precision temperature measurement results.
• Specific parameters of interest: Thermoelectric potential output varies with temperature changes, typically at the microvolt (μV) level.
• Specific application areas: Often used for temperature measurement and control in high-temperature processes such as steel smelting and aluminum plants.

Thermocouple wire type S:

S-type thermocouple bare wire also uses platinum-rhodium alloy wire (platinum 90%, rhodium 10%) and platinum-rhodium alloy wire (platinum 94%, rhodium 6%) as thermocouple materials. It has a wide temperature measurement range (usually from 0 degrees Celsius to 1768 degrees Celsius), high accuracy and reliability, and is suitable for industrial control and scientific research applications in various high temperature environments.

• Temperature range: Suitable for a wide temperature range, typically measuring temperatures from 0°C to 1,600°C (32°F to 2,912°F).
• Advantages: It has excellent linear characteristics and stability and is suitable for a wide range of temperature measurement needs.
• Specific parameters of interest: Thermoelectric potential output varies with temperature changes, typically at the microvolt (μV) level.
• Specific application fields: Widely used in temperature measurement and control in the oil and gas industry, furnace and heat treatment industry, and steel metallurgy.
