Pt100 RTD Sensor Assembly

Overview

The industry-standard 100 Ω at 0°C platinum RTD with temperature coefficient α = 0.00385 Ω/Ω/°C. Pt100 elements are calibrated to IEC 60751 and offered with NIST-traceable certification for the most demanding measurement applications.

Key Features

• 100 Ω nominal resistance at 0°C, α = 0.00385 standard
• Thin-film and wire-wound elements for full range coverage
• Accuracy classes AA, A, B, and 1/3 DIN to suit any tolerance budget
• Fast t90 response — as low as 0.15 s in thin sheath, moving water
• Self-heating coefficient ≤25°C/W (typical) minimizes measurement error
• Insulation resistance >100 MΩ at 25°C for stable long-term operation
• Optional NIST-traceable, multi-point calibration with R-vs-T data

Applications

• Precision laboratory and metrology references
• Pharmaceutical and biotech process monitoring
• Semiconductor fabrication tools
• Aerospace test cells and engine instrumentation
• Power generation and steam-cycle measurements
• Custody-transfer and energy-balance calculations
