General-Purpose Thermocouple Configurator

Configuring a thermocouple for uses outside the plastics industry? Use this configurator instead.

Plastics Thermocouple Configurator

This configurator has been designed so that we can build any thermocouple it specifies. In addition, if you find that you need to create a thermocouple that isn't within the ranges allowed by this configurator or the standard thermocouple configurator, it might still be possible for us to build what you need. Just give us a call at (866) 685-4443 and we'll work on figuring out a solution for your application.

The thermocouple types listed below are commonly used in the plastic processing industry. These assemblies can be used in a variety of different applications, from extruders to surface temperature sensors. For other thermocouples, please use our standard thermocouple configurator.

To configure a thermocouple, just click on the type of thermocouple you're ordering, choose the specifications you need, and then press the Submit button to get your price.


Armor Adjustable Immersion Thermocouple

Melt Bolt Thermocouple

Info Img
The melt-bolt thermocouple is made of 300 series stainless steel and is constructed using a fiberglass or metal-sheathed MgO insulated element. This style of thermocouple is used on extruders and injection molding machines to directly measure the melt temperature of plastic as it moves down the extruder barrel.

Thermocouple Insulation:


Tip Diameter (in.):
"D" Dimension
5/32"


Tip Length (in.):
"T" Dimension
Adjustable range 0" to 1"

Threaded Nozzle Thermocouple

Info Img
The threaded nozzle thermocouple is generally used to measure the temperature of the nozzle of an injection molding machine. This style is not in direct contact with the molten plastic. Due to the relatively small size of this sensor, other general areas of use include mounting in bearing housings, sealing bars, heat plates, and other limited space applications.

Thermocouple Type:


Measuring Junction:


Tip Diameter (in.):
"D" Dimension

Nozzle Length:
"C" Dimension

Nozzle Threads:
1/4" - 28


Extension Leadwire:
"B" Dimension
Fiberglass Insulation

Ring Thermocouple

Info Img
These ring type assemblies have the thermocouples embedded either into a stainless steel stamping for grounded junctions or a brass ring for ungrounded junctions. Various ring sizes are available to measure the surface temperature of nozzles, extruder barrels, die heads, molds, and many other applicable surfaces.

Thermocouple Type:


Measuring Junction:


I.D. Ring Size (in.):

Width (in.): 3/8"
Length (in.): 5/8"
Screw Size: #6 - #10 4mm - 5mm


Extension Leadwire:
