Style F - Transition Assembly

Style F – Transition Assembly

1. Transition

Select One:

A durable stainless tube which allows for the mechanical and electrical attachment of the lead wire to the metal sheathed, minerally insulated thermocouple probe.

2. Calibration

Select One:

Maximum temperature limits for each ANSI type thermocouple material vary by sheath material, application atmospheres, wire gauge, insulation, and epoxy.

3. Junction

Tip Style:		Tip style defines the shape of the thermocouple sensing tip. Tip junction type affects performance and life, e.g., ungrounded for isolation, grounded for faster response.
Type:

4. Element Type

Select One:

Up to three thermocouples in one sheath. Each can be wired separately if ungrounded.

5. Sheath Operating Temperature

Select One:

Application temperature affects sensor calibration, material, and size.

6. Sheath Material

Select One:

Material depends on application conditions. 304SS/316SS are common; others for corrosion/high temp.

7. Sheath Diameter

Select One:

Size impacts durability and temperature rating. Larger sizes preferred for high-temp use.

8. Sheath Length “L”

Enter Inches:

Although the accuracy of the thermocouple is not affected by the length of the sheath, consult the factory when the probe length exceeds 120 inches.

9. Leadwire Construction

Material:		Know the application atmosphere and limitations – temperature, moisture, corrosion, and abrasion. Flexible wire is available in solid or stranded conductors with many sizes, insulations and calibrations to meet nearly all applications.
Configuration:

10. Leadwire Gauge

Select One:

Insulated wire, solid or stranded, in a variety of insulations is carried in the most common sizes from 16 to 24 gauge.

11. Leadwire Length “A”

Enter Inches:

There is no limit to the leadwire length, however when the distance to the instruments is 150 feet or more, a 4-20ma signal conditioner is recommended.

12. Leadwire Terminations

Select One:		The type of termination selected may be restricted by the wire gauge.
	For Plugs and Jacks Only:

Temperature:
Clamp:

13. Fittings

Select Type:		Fittings of all thread sizes, materials and design are available for most applications.
	(For Compression Fittings and Fixed Bushing only)
Select NPT:

14. Fitting Location “F”

Enter inches from tip (“N” for None, “L” for Loose):

Measured from the first thread to the tip of the sheath. Allow for the thread-in insertion length of the fitting when determining location.

15. Special Options

These are the most common options for this assembly. Click “more info” for other options and choose all that apply.

16. Bend Angle

Select One:

Mineral insulated thermocouples should not be bent on a radius smaller than twice the outside sheath diameter.

17. Bend Location “C”

Enter inches from tip (“N” for None):

There are minimum bend locations for all Mineral Insulated sensors – dependent on sheath diameter.
