Tungsten filaments can be used to make high-performance sensors, mainly based on their unique physical and chemical properties. Here are some of the applications and benefits of tungsten wire in high-performance sensors:
- High Melting Point and High Temperature Resistance
High-temperature applications: Tungsten has a high melting point of 3422°C, making it ideal for sensors in high-temperature environments, such as gas temperature sensors and high-temperature pressure sensors.
- Excellent electrical conductivity
Current conduction: Tungsten has good electrical conductivity and can be used to make resistive sensors, such as thermocouples and resistance temperature detectors (RTDs), with high accuracy and stability.
- Strength and toughness
Mechanical properties: Tungsten’s high strength and toughness allow it to withstand mechanical shock and pressure, making it suitable for sensors used in harsh conditions.
- Corrosion resistance
Chemical stability: Tungsten performs well in many corrosive environments, so it can be used in environmental monitoring sensors, especially those in chemical or radiation environments.
- Thermal responsiveness
Thermal conductivity: Tungsten has high thermal conductivity, which helps the sensor respond quickly to temperature changes, making it suitable for sensors for precise temperature measurement.
- Application scenarios
High-temperature sensors: In fields such as aerospace, metallurgy, and nuclear energy, tungsten wire can be used in temperature and pressure sensors in high-temperature environments.
Current sensor: Tungsten wire can also be used in current sensors, especially in applications that require high precision and high stability.
- Considerations
Processing difficulty: The hardness and brittleness of tungsten may pose some challenges when processing into sensor components.
Cost: The relatively high cost of tungsten may limit its use in certain applications.
