Description

Fabricated thermowell with threaded process and thermometer connections Generally the material chosen for a specific installation is governed by corrosion conditions to which the thermowell is exposed. In some instances, strength is a primary requirement while corrosion resistance is secondary. For accuracy of the temperature measurement, the immersion length should be long enough to permit the entire temperature sensitive portion of the thermometer bulb, or the thermocouple element, to project into the temperature medium to be measured.

    • For accuracy, the immersion length should be long enough to permit the entire temperature sensitive portion of the thermometer bulb, or the thermocouple element, to project into the temperature medium to be measured.
    • Thermocouples have a short sensitive portion and can be used with protection tubes having short immersion lengths. Resistance (RTD) thermometers have sensitive portions between 25 and 50 mm long.
    • Generally the material chosen for a specific installation is governed by corrosion conditions to which the thermowell is exposed.
  • Field of application Thermowells serve as protective devices for the primary detecting elements, e.g. RTD's and thermocouples for temperature control, recording and indicating of various processes.
