Xiatech T6WZP05 Series Face-Mount Platinum Resistance Thermometers

Overview

The Xiatech T6WZP05 Series Face-Mount Platinum Resistance Thermometers are precision temperature sensing devices engineered for direct surface temperature measurement of rotating or stationary metallic components—particularly bearing housings, journal surfaces, turbine casings, and other critical machine interfaces where axial thermal gradients and rapid transient response are essential. Based on the fundamental principle of platinum resistance thermometry (Pt100 per IEC 60751:2022), these sensors utilize a thin-film or wound-wire platinum element tightly bonded to a flat, thermally conductive measuring face. This face-mount architecture minimizes interfacial thermal resistance and eliminates the lag associated with conventional axial-probe configurations, enabling true surface temperature capture with high spatial fidelity and sub-second thermal response times (typical τ₉₀ ≤ 1.5 s in oil-lubricated metal contact).

Key Features

• Face-mounted Pt100 sensing element conforming to Class A tolerance (±(0.15 + 0.002|t|) °C) per IEC 60751:2022, ensuring metrological traceability and long-term stability;
• Hermetically sealed stainless steel outer sheath (AISI 316L or equivalent) providing mechanical robustness, corrosion resistance, and IP67-rated environmental protection;
• Dense, high-purity alumina (Al₂O₃) ceramic insulation filling the internal cavity, delivering dielectric strength >1 kV AC and exceptional resistance to oil degradation, moisture ingress, and particulate contamination;
• Optimized thermal interface geometry: flat, polished 6 mm diameter measuring face with controlled surface roughness (Ra ≤ 0.8 µm) for consistent contact conductance across mating surfaces;
• Low thermal mass design achieved through minimal platinum wire mass and direct thermal coupling, supporting dynamic temperature monitoring in rotating machinery applications;
• Standard 4-conductor lead configuration with PTFE-insulated, shielded twisted-pair cabling for noise immunity and accurate 4-wire RTD measurement compensation.

Sample Compatibility & Compliance

The T6WZP05 series is validated for direct mounting onto machined steel, cast iron, aluminum, and bronze surfaces via threaded inserts (M6×0.75 or M8×1.0 standard), thermal paste application, or spring-loaded clamping fixtures. It complies with industrial installation requirements defined in ISO 10816-3 (vibration condition monitoring) and supports integration into condition-based maintenance (CBM) systems. While not certified for hazardous areas, its construction meets general-purpose industrial safety standards (IEC 61000-6-2/6-4 for EMC). The sensor’s temperature range (0 °C to +200 °C) aligns with common operational limits for hydrodynamic bearings, gearboxes, and electric motor end shields. Calibration certificates (as-found/as-left) are available per ISO/IEC 17025-accredited laboratories upon request.

Software & Data Management

As a passive analog transducer, the T6WZP05 requires connection to a compatible signal conditioning system—such as Xiatech’s TC-2000 series temperature acquisition modules or third-party DAQ platforms supporting 4-wire RTD input (e.g., National Instruments CompactDAQ, Keysight 34972A). When integrated into SCADA or MES environments, it supports time-synchronized data logging with timestamp resolution ≤ 10 ms. For quality-critical applications, the sensor may be deployed within GLP/GMP-compliant workflows when paired with calibrated readout instruments featuring audit-trail functionality and 21 CFR Part 11–compliant electronic records (where applicable). Raw resistance values (Ω) are linearized using the Callendar-Van Dusen equation in firmware or host software, ensuring traceable conversion to temperature units.

Applications

• Real-time surface temperature monitoring of plain bearings and thrust collars in turbomachinery;
• Thermal validation of lubrication film integrity in high-load journal bearings;
• In-situ temperature profiling across gearbox housing faces during endurance testing;
• Surface temperature mapping of motor stator frames and rotor end rings under load;
• Calibration reference points for infrared pyrometers in metallurgical furnace roll cooling zones;
• Validation of CFD thermal models for heat transfer at solid-fluid interfaces in rotating equipment.

FAQ

What is the recommended mounting torque for the T6WZP05 sensor?
For M6×0.75 threads, maximum tightening torque is 3.5 N·m; for M8×1.0, it is 6.0 N·m. Exceeding these values may deform the measuring face or compromise hermetic seal integrity.
Can the T6WZP05 be used in vacuum environments?
No—its ceramic insulation and internal fill are not rated for vacuum service; outgassing and thermal conductivity shifts may occur below 10⁻² mbar.
Is the sensor suitable for steam turbine casing applications?
Yes, provided surface temperature remains within 0–200 °C and thermal cycling does not exceed 5 K/min to avoid differential expansion stress at the interface.
Does Xiatech provide calibration services for this model?
Yes—NIST-traceable calibration at three points (0 °C, 100 °C, and 200 °C) is offered with uncertainty budgets compliant with ISO/IEC 17025.
How is interchangeability ensured across multiple T6WZP05 units?
All units undergo individual characterization and are supplied with unique R₀ (resistance at 0 °C) and Callendar-Van Dusen coefficients, enabling plug-and-play replacement without system recalibration.
