Thermocouple with Hygienic Process Connection
All wetted parts of the PPL6-T hygienic thermocouple sensor probe are fabricated from 316 stainless steel and are TIG welded in our own workshop. The process of TIG welding gives a very clean consistent weld which is closely inspected to ensure there are no pits or crevices which may form dirt traps.
We can manufacture your thermocouple probe to almost any stock diameter with both metric and imperial sizes readily available. Most customers use 6mm but others are just as easy to provide from 3mm upwards.
The connection type is the choice of our customer and we generally supply whatever is needed to fit directly to the connections you already have fitted on your equipment. All we need to know is the pipe size and the fitting specification, we will do the rest. We stock the most common types such as Tri-Clamp, RJT and IDF. We don’t normally supply the seals or clamps but are happy to do so should this be necessary.
We stock a variety of terminal heads that cover all eventualities. The most popular for our hygienic sensors is 316 stainless steel. We do however also offer other materials such as Aluminium Alloy, ABS, Nylon and FDA-approved Polypropylene. 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.

The uses of a thermocouple PPL6-T sensor is suitable for the measurement of liquids and gases across a wide temperature range
The temperature sensor is also available as a PPL6-T resistance thermometer sensor. We are also able to supply the probe with your choice of thermistor sensor.
All of our type k thermocouples, r type thermocouples, n type thermocouple, n type thermocouple and thermal couplers are custom-built based on your application requirements. Please contact us for more information, or for a free quote.
What is a Thermocouple Used For?
A thermocouple is used for measuring temperature and comprises two dissimilar metallic wires joined together to form a junction. When the junction is hot or cold, a small voltage is generated in the electrical circuit of the thermocouple which can be measured, and this corresponds to temperature.
Any two metals can be used to make a thermocouple but in practice, there are a fixed number of types that are commonly used. They have been developed to give improved linearity and accuracy and comprise specially developed alloys.
Thermocouples can be made to suit almost any application. At Process Parameters, we design and manufacture custom-built thermocouples based on your requirements. Contact our experts for more information, or for a no-obligation quote.
