Industrial production——
- Metallurgical industry: used to measure the temperature of
high-temperature furnaces, heating furnaces, steel rolling
equipment, etc. For example, in the steelmaking process, the
temperature in the furnace needs to be accurately measured to
control the smelting process.
- Chemical industry: used to monitor and control the temperature in
chemical reactors, distillation towers, heating furnaces and other
equipment to ensure the normal progress of chemical reactions.
- Machinery manufacturing: used to measure and control the
temperature in heat treatment equipment, forging furnaces, and
casting furnaces to ensure the performance of materials.
- Power industry: used for temperature monitoring of power generation
equipment, such as boilers, steam turbines, etc., to ensure the
safe operation of equipment.
- Temperature compensation function: reduces the measurement error
introduced by the cold end temperature fluctuation and improves the
stability of temperature measurement.
- Low resistance: The compensation wire is usually made of
high-purity copper or copper alloy material with low resistance
value, which can effectively reduce the voltage drop during signal
transmission and ensure the integrity of the measurement signal.
- Anti-interference ability: During the design and manufacturing
process, the compensation wire usually adopts shielding measures,
such as braided shielding or aluminum foil shielding, which can
effectively resist external electromagnetic interference and ensure
the stability and accuracy of the measurement signal.
