Thermocouples

Expert Thermocouple Manufacturer

Since 1997 we have been designing and manufacturing thermocouples for clients all over the world. Unlike some thermocouple suppliers we are focused solely on the manufacture of temperature sensors. We have seen the temperature sensor market mature but we continue to manufacture sensors to an ever growing range of industries, from traditional sensor users such as cryogenics and glass manufacture, to emerging industries such as low emission testing and industrial compost manufacture.

What is a Thermocouple?

A thermocouple (TC) is a sensor that is used to measure temperature. It consists of two wire conductors made out of different metals. When these metals are welded together, a junction is formed. The temperature can be calculated by working out the voltage generated when a temperature change is detected.  There are a number of different TC types and designs that  each performs best at certain temperatures and in specific environments.

If you are unsure exactly what you need, get in touch and we can help identify your requirements.

Our customer service and quality of our manufacturing has earned us great customer relationships:

“I found all the staff at Peak Sensors to be very friendly, professional and prepared to go the extra to make sure all our bespoke requirements were met. A top rate service that I would definitely recommend. ”

Designs we manufacture include:

Rare Metal Thermocouple Assemblies

Peak Sensors manufacture rare metal assemblies, also called noble metal thermocouples or Platinum/rhodium alloy thermocouples, and can provide bespoke/custom designed sensors to your process or work to your specification and drawings. All types of rare metal TC can be supplied including Type R, Type S or Type B.

Base Metal Thermocouple Assemblies

Base metal assemblies are commonly made from various nickel alloys. Different combinations of nickel alloys have become popular industry standards. We can manufacture bespoke/custom designed sensors to your process or work to your specification and drawings in all common thermocouple types including: Type K, Type J, Type N, Type E and Type T.

Mineral Insulated Thermocouples

MI thermocouples are a stable, durable temperature measurement solution. MI TC’s consist of an outer metal sheath, which has an inner filling of magnesium oxide powder. This powder surrounds the conductors providing great thermal conduction and also enabling the sensor to be bent into various shapes without affecting the measuring point.We are able to offer mineral insulated sensors in both simplex and duplex assemblies.

MTM

Cable Thermocouples

In cable thermocouples the sensor conductors are protected by flexible cable insulation. Depending on requirements the insulation can be PVC, Silicon rubber, PTFE or Glass fibre. There are many different designs of cable TC that are suitable for almost any application.

CTE

Thermocouple Inserts and Elements

Inserts can be inexpensive to produce and are ideal for insertion into an existing thermowell assembly. We can also supply various thermocouple elements for use in your own designs or to replace your existing broken elements.

MTI

Hand Held Thermocouple Probes

We can supply an extensive range of hand held thermocouple probes for use in a variety of environments. Most hand held probes come with a mini plug for connection to hand held instrumentation.
