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	A	B	d
 Meet ASME PTC 19.3 TW standard with flexible design
		t

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.

Order Thermowell Calculation option (R21) to receive a formal report with product shipment.

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 thermowell overview

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.

Rosemount 114C Flanged Thermowells

June 2019	Rosemount 114C

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





Adequate for	 Highest fatigue
most process	resistance per
applications	ASME PTC 19.3
Weld withstands	TW
same pressure	 Eliminates weld
and temperature rating as flange	qualifications and failures

 Emerson recommended option

 Lower cost than full penetration weld

 Used in extreme process applications
