Introduction:
Type E thermocouple bare wire is a commonly used thermocouple type used for temperature measurement and control. It is composed of nickel-chromium alloy (Chromel) and copper-nickel alloy (Constantan). Type E thermocouple bare wire is suitable for medium temperature ranges, typically measuring temperatures from -200°C to 900°C. This type of thermocouple has good linear characteristics and low drift, providing relatively accurate and stable temperature measurements.
E-type thermocouple bare wire is widely used in industrial control fields, including heating equipment, furnace temperature monitoring and heat treatment processes. It is also widely used in environmental monitoring, such as weather stations, greenhouses and warehousing environments. In scientific research and laboratories, E-type thermocouple bare wires are often used to measure sample temperature and conduct thermodynamic experiments.
Characteristic:
- Thermocouple material: Type E thermocouple bare wire is composed of nickel-chromium alloy (Chromel) and copper-nickel alloy (Constantan). Chromel is the positive pole of the E-type thermocouple and Constantan is the negative pole.
- Temperature range: Type E thermocouple bare wire is suitable for medium temperature ranges, typically measuring temperatures from -200°C to 900°C (-328°F to 1652°F).
- Linear characteristics: E-type thermocouple bare wire has good linear characteristics within its operating temperature range and can provide relatively accurate temperature measurements.
- Low drift: Type E thermocouple bare wire has low drift characteristics and can maintain relatively stable temperature measurements.
Advantage:
- Widely used: Type E thermocouple bare wire is one of the most commonly used thermocouple types and is widely used in various industrial fields and laboratory environments.
- Corrosion resistance: E-type thermocouple bare wire has good corrosion resistance to oxidizing and reducing gases, and is suitable for temperature measurement in some chemical industries and corrosive environments.
- Fast response: E-type thermocouple bare wire has fast temperature response capability and can quickly reflect temperature changes.
Relevant specific parameters:
- Temperature range: -200°C to 900°C (-328°F to 1652°F)
- Thermoemf output: Varies based on temperature changes, usually in the microvolt (μV) level.
- Linear characteristics: has good linear characteristics.
- Sensitivity: Varies based on specific model and manufacturer.
