7.3.4 Measuring inserts: Diameter and standard lengths
The diameter the thermometer's measuring insert must have depends on the existence of a
thermowell and its tip:
• Thermowell with reduced tip: Measuring insert with Ø 3 mm / 0.12"
• Straight thermowell and thermowell with tapered tip: Ø 6 mm / 0.24"
• Version without thermowell: Ø 6 mm / 0.24"
Insertion-type thermometer (TRA/TCA-P10/20/40)
Threaded thermometer (TRA/TCA-S11/21)
INFORMATION!
The lengths given for the thermowells and measuring inserts in the following tables are
standard lengths. The manufacturer can provide other lengths on request.
