Frequently Asked Questions

What are thermocouple connectors, and why are they important?
Thermocouple connectors are used to connect thermocouples to measurement devices or other equipment. They provide a reliable connection for transmitting the temperature signal from the sensor while ensuring accurate and consistent readings. The choice of connector material and temperature rating is crucial to ensure that the connector performs well in various environments, especially at high temperatures.
What are the different temperature ratings available for your thermocouple connectors?
We offer thermocouple connectors in three temperature ratings: 425ºF, 660ºF, and 1200ºF. The temperature rating you need will depend on the maximum temperature the connector reaches. For most applications, the 425ºF rated connector is suitable, while for more demanding applications with higher ambient temperatures, the 660ºF or even 1200ºF ceramic connectors are better suited.
Do you offer accessories for thermocouple connectors?
Yes, we offer a wide range of accessories for thermocouple connectors, including sensor and cable supports and adaptors, mounting brackets and protective covers. These accessories are designed to enhance the functionality and reliability of our thermocouple connectors, ensuring ease of installation and long-lasting performance. If you need specific recommendations, feel free to contact our engineers for assistance.
What is a thermocouple connector panel?
A thermocouple connector panel is a centralised unit designed to house multiple thermocouple connectors, allowing for organised and efficient connection of multiple thermocouple sensors to measurement equipment. It streamlines the wiring process and ensures secure, reliable connections in applications requiring multiple thermocouples. Available in both aluminium and stainless steel, these panels come in various configurations and capacities to suit different needs.

When to use a Thermocouple Connector

Although the simplest of thermocouples end in bare wires (as found in many laboratory and industrial/research applications, for example), there are many other applications where a connector is usually desirable to make life easier.

We manufacture miniature and standard size thermocouple connectors which are available for use with all common thermocouple types and for use with copper conductors in applications involving resistance thermometers. For thermocouple applications, thermocouple grade alloys are incorporated in the contact parts of the connector. This avoids the generation of unwanted EMFs if the connector is not held at uniform temperature.

The connector is usually used to connect the thermocouple sensor to thermocouple or extension cables, then on to the reference junction and the instrumentation concerned. The connectors allow for rapid fitting or exchange of sensors without sacrificing thermocouple conductor uniformity. Plug and jacks are designed so that their installation can be made simply and securely, with designed-in locking mechanisms. Plugs and jacks are polarized by size and are usually marked for negative and positive polarity. Although there is no standard as such, connectors are generally pin compatible with devices from several manufacturers.

In general, although connector bodies for thermocouples are color coded in accordance with the thermocouple standards (ANSI MC96.1), bodies of the higher temperature rated devices are colored brown or white (depending on maximum temperature), irrespective of their thermocouple code. Bodies are then marked with their thermocouple type letter only.

Accessories include connector panels (standard and miniature), for stacking of jacks in multiple thermocouple applications, and barrier terminal strips. The latter have lugs marked to identify both alloy and polarity, and are available for most of the common standard types of thermocouple as well as copper wires for resistance thermometers.
