5.2 Recomendaciones de reemplazo
Insufficient temperature range: Adopt 68 standard sheath model 6R8HCI-68, range extended to -50°C～400°C
Higher accuracy required: Select 7R8HCI-58-C (Class A accuracy, ±0.15°C @ 0°C)
Severe corrosion environment: Use 6R8HPI-58-C (Hastelloy) or 6R8HCI-58-T (Titanium) sheath
Faster response required: Choose 68Q fast-response series, response time reduced to 5 artículos de segunda clase
4-wire measurement needed: Select 6R8HCW-58-C to eliminate all lead resistance error
5.3 Precauciones de aplicación
- Trim the 58C sheath to required length with a standard pipe cutter before installation; reserve sufficient length for connection head assembly.
- Keep three lead wires equal in length for optimal resistance compensation in 3-wire connection.
- Avoid long-term operation above 392°F (200°C), exceeding the 58C sheath temperature limit.
- Ensure full contact between sensor tip and thermowell bottom during installation to minimize measurement error.
- Regularly inspect connection head sealing to prevent moisture ingress and accuracy drift.
- When matched with temperature transmitters (p.ej. Rosemount 3144S), correctly configure sensor type and parameters in the transmitter.
