Industrial Thermocouple Sensor with KNE Connection Head & Thread
The custom-built PPL4-T thermocouple temperature sensor is suitable for the measurement of liquids and gases across a wide temperature range of -50 to +250°C.
All wetted parts of the threaded thermocouple probe are normally made from 316 stainless steel are TIG welded to give a pressure-tight housing for the sensor.
Many metric and imperial probe diameters are available from 3mm upwards. Many thread types are available. They are generally BSP, BSPT or NPT types but we can supply others to your requirements such as Metric, UNF etc.
At Process Parameters, we stock a variety of terminal heads that cover all eventualities. The most popular thermocouple head is the aluminium alloy KNE head which is commonly used in the industry for industrial thermocouple probes.
We do however also offer other materials such as ABS, Nylon, FDA approved Polypropylene and of course 316 stainless steel for the most demanding applications. Most of our terminal heads have IP ratings of IP67 or IP68.
We can fit a number of options inside the terminal heads that best fit your requirements. The simplest is a terminal block allowing you to connect directly to the sensor.
Alternatively, we can supply temperature transmitters with either a 4-20mA or a 0-10V output. Other options include intrinsically safe transmitters or those with HART protocol. We can also fit in head displays if required.
Thermocouple Head Types:
- A – KNE Aluminium Alloy, IP68
- B – KSE Aluminium Alloy, IP68
- C – ABS, IP67
- D – Glass Filled Nylon, IP65
- E – 316 stainless steel, IP68
(Other heads available upon request)
Thermocouple Head Options:
- A – Ceramic Terminal Block
- B – In Head Transmitter—SEM203P (Specify Range)
- C – Tails for Customers Own Transmitter
Additional Thermocouple PPL4-T Information
The PPL4-T thermocoupler is ideal for direct installation into your process or for use with our PPL51-TW pocket. The PPL4 is also available as a resistance PPL4-P thermometer sensor. We are also able to supply the thermocouple with your choice of thermistor sensor.
We offer a comprehensive calibration service and a wide choice of accessories.
Our PPL4-T is made to order based on your application. If you’d like more information or have any questions, please contact us for a quote.
What is a Thermocouple?
A thermocouple is a temperature sensor made of two different metal wires joined together. When exposed to heat, it produces a small electrical voltage that changes with temperature. It’s commonly used to measure temperature in industrial processes and provides a simple and reliable way to monitor and control temperature.

How Does a Thermocouple Work?
A thermocouple works by taking advantage of the fact that different metals produce a small electrical voltage when they are heated. By connecting two different metal wires together, the temperature difference between the junction and the other end generates a voltage that can be measured to determine the temperature.
