Phosphor bronze four-strand non-ferromagnetic phosphor bronze temperature measurement wire 36AWG

Phosphor Bronze Four-Core Twisted Pair Non-Ferromagnetic Phosphor Bronze Temperature Measurement Wire 36AWGThe Phosphor Bronze Four-Core Twisted Pair 2-pair 4-strand twisted temperature measurement wire (36AWG) is a precision wire specifically designed for temperature measurement applications. It combines the advantages of material properties, structural design, and specification parameters, making it suitable for temperature measurement scenarios that require high signal transmission accuracy and environmental adaptability. The following details its core elements:

1. Core Material: Phosphor Bronze
Characteristics: Phosphor bronze is an alloy based on copper, with the addition of phosphorus and small amounts of tin, lead, and other elements. It offers excellent electrical conductivity (close to that of pure copper, ensuring low-loss signal transmission), corrosion resistance (suitable for humid and mildly chemically contaminated environments), and mechanical strength (resistant to stretching and bending, extending the wire's service life).
Role in Temperature Measurement: As the conductor, phosphor bronze ensures stable transmission of weak electrical signals generated by temperature sensors (such as thermocouples or RTDs), reducing measurement errors caused by unstable material resistance.
2. Structural Design: 2-Pair 4-Strand Twisted Pair
Strand Count and Twisting Method: The wire consists of 4 individual strands, divided into 2 groups (each pair consists of 2 strands), using a twisted pair process (i.e., each pair of wires is twisted together).
Advantages:
Anti-Interference: The twisted pair structure of phosphor bronze cancels out external electromagnetic interference (e.g., from motors or high-frequency equipment), preventing interference signals from mixing with temperature measurement signals and ensuring data accuracy.
Structural Stability: The twisted design makes the wire more flexible, facilitating routing (especially in confined spaces or scenarios requiring bending), while reducing the risk of breakage due to uneven stress on individual strands.
3. Specification Parameters: 32AWG
Meaning of AWG: AWG (American Wire Gauge) is a standard for measuring wire diameter, where a larger number indicates a smaller wire diameter. 32AWG corresponds to a conductor diameter of approximately 0.202 mm (with insulation, about 0.5-0.8 mm).

Special Wire for Vacuum EnvironmentsFeatures:

Small Diameter Advantage: Suitable for scenarios with strict size limitations (e.g., inside precision instruments or for micro-sensor connections), saving installation space.
Limitations: Due to its small cross-sectional area, the long-term allowable current is relatively low (typically ≤0.5A). It is primarily used for transmitting weak signals (temperature measurement signals are often at mV or μA levels) and is not suitable for high-power applications.
4. Application Scenarios
Based on the above characteristics, this wire is mainly used in high-precision temperature measurement systems, such as:
Internal temperature measurement in industrial equipment (e.g., chips, motor windings, precision instrument chambers);
Medical devices (e.g., constant temperature incubators, localized human temperature probes);
Environmental monitoring (e.g., laboratories, cleanrooms, and other scenarios requiring anti-interference capabilities);
Aerospace applications (temperature monitoring of components in confined spaces).
5. Ultra-Low Temperature Sensor WireSummaryThe core value of the Phosphor Bronze Four-Core Twisted Pair 2-pair 4-strand temperature measurement wire (32AWG) lies in: ensuring signal transmission stability with phosphor bronze, enhancing anti-interference capabilities through the twisted pair structure, and adapting to precision scenarios with the 32AWG small-diameter design. The combination of these three factors makes it an ideal choice for weak temperature signal transmission, particularly suited for high-precision temperature measurement needs in space-constrained and electromagnetically complex environments.
