Thermowell Diameters

• 18 mm (0.71 in), 24 mm (0.94 in), or 26 mm (1.02 in).

Insert Diameters

• 3 mm (0.12 in) or 6 mm (0.24 in).

Electrical

• Output Signals: 4 to 20 mA, HART®, PROFIBUS® PA, FOUNDATION Fieldbus™, PROFINET®.

Accuracy

• Thermocouple Accuracy: Refer to IEC 60584 and ASTM E230/ANSI MC96.1 for standard and special tolerances.
• RTD Accuracy: Refer to IEC 60751 for Class A, AA, and B tolerances.

Response Time

• Calculated at approx. 23 °C in running water (0.4 m/s flow rate, 10 K excess temperature). Specific values vary based on thermowell diameter, tip length, and sensor type (RTD/TC).
• Example for RTD, 18 mm thermowell, U=65 mm: t50 = 22 s, t90 = 60 s.
• Example for TC, 18 mm thermowell, U=65 mm, grounded: t50 = 7 s, t90 = 18 s.
• Insert response times: Faster values are provided for the insert alone, tested in flowing water.

Insulation Resistance
