Rosemount 114C Thermowell
Product overview
Temperature sensors are rarely inserted directly into an industrial process. They are installed into a thermowell to isolate them from the
potentially damaging process conditions of flow-induced stresses, high pressure, and corrosive chemical effects. Thermowells are
closed-end metal tubes or barstock installed into the process vessel or piping and become an integral pressure-tight part of the process
vessel or pipe. They permit the sensor to be quickly and easily removed from the process for calibration or replacement without requiring
a process shutdown and possible drainage of the pipe or vessel.
The Rosemount 114C Thermowell is made from solid barstock to ensure strength and integrity. The Rosemount 114C was designed to
accommodate a host of industry standard configurations, but has the flexibility to adapt to special configurations for different types of
applications.
Flexible design modifiers accommodate many process requirements
Different sizes of root (A), tip (B), and bore (d) diameters
Different tip (t) thickness as required
Numerous combinations for various industrial applications
Meet ASME PTC 19.3 TW standard with flexible design

Thermowell calculations ensure thermowell design is compatible with process conditions
Thermowells inserted into any process are subjected to forces
from the fluid flow.
ASME released design standard PTC 19.3 TW that defines a
series of qualitative calculations to determine design suitability
to withstand process conditions.
Calculations are based on process conditions, process fluid,
installation method, thermowell geometry and material.
The thermowell calculation tool from Emerson is designed to
meet the ASME standard.
The free online software version can be used for preliminary
calculations. Click here to access the tool.
Formal calculations by our expert team of engineers are
available prior to order placement to ensure design is
acceptable.
Recommendations are also made if thermowell design is found
to be unacceptable for the application.

Selection guide
Ensure sensor fits thermowell
Rosemount 114C Head length (H) + Immersion length (U) = Rosemount 214C Sensor insertion length (L).
Basic selection guide
Selecting the proper thermowell for an application is an important activity as it impacts plant safety and measurement efficiency.
Thermowells are considered a wetted part; they physically become part of the pressure retaining system.
The four major factors to consider when selecting a thermowell for an application are described below:
Thermowell length
There is no standard formula to determine thermowell immersion length. However, there are a few common practices that the
process industry follows along with good engineering judgment. Ideally the thermowell tip should be located near the centerline in
turbulent flow conditions because this represents the most accurate process temperature.
To ensure optimal performance, a general guideline for immersion length into a pipe is as follows:
10⫻ the thermowell root diameter for air or gas
5⫻ the thermowell root diameter for liquids
Another guideline is at least one-third the way into the pipe for any measurement. The American Petroleum Institute (API) has a
specific recommendation of using an immersion length of the sensing element plus 50 mm (2-in.).
Mounting configuration
Consider how the thermowell is mounted on the pipe or tank. The process designer typically specifies what mating connection will
be used and the thermowell selected should match that connection. Temperature, pressure, and material are usually taken into
consideration to ensure the process connection will be adequate for the application. Welded, threaded, flanged, and Van Stone are
standard mounting configuration options.
Thermowell stem profile
Factors to be considered when selecting a stem style include the process pressure, required response speed of the measurement,
drag force of the fluid flow on the well, and the wake frequency. The stem or shank is the part of a thermowell inserted into the
process piping or vessel. Straight, stepped and tapered stem styles are available. Each profile has its advantages depending on the
need and situation.
Thermowell material
Rosemount Thermowells are supplied in most materials required for industrial applications. Standard materials are 316/316L
Stainless Steel, 304/304L Stainless Steel, and A105 Carbon Steel. For corrosive environments, special materials such as Alloy C-276
and Alloy 600 are also available. See the ordering table for a complete listing of standard materials. Contact your local Emerson
representative for additional material availability.

Threaded thermowells are threaded into a process pipe or tank, allowing for easy installation and removal when necessary. While this
is a common mounting method, it has the lowest pressure rating of all mounting configuration options.

Threaded installation
Threaded thermowells are screwed into the process using a threaded fitting or directly into a tapped pipe if there is sufficient wall
thickness. Tapered threads will deform to each other to create a seal. Thread sealant and appropriate torque should be applied to
reduce risk of leaks.

Flanged thermowell overview
All Rosemount flanged thermowells are manufactured in accordance with ANSI B16.5. The flange to stem weld is in accordance to
ASME Section IX. There is also full traceability with material certifications available on request. Rosemount flanged thermowells are
available in two manufacturing configurations: full and partial penetration welds.
Full penetration weld (F) Partial penetration weld (P) Forged, no welds (G)
Stronger weld
joint per ASME
PTC 19.3 TW
Used for heavy
duty
applications
Emerson recommended option
Figure 8. Standard Offering–Flanged
Adequate for
most process
applications
Weld withstands
same pressure
and temperature rating as flange
Lower cost than full penetration weld
Highest fatigue
resistance per
ASME PTC 19.3

Eliminates weld
qualifications and failures
Used in extreme process applications
The common options shown in Figure 8 represent a partial offering; reference the Rosemount 114C Flanged Ordering Information
for a full list of available options.
