Spring Loaded Thermocouple Temperature Sensor
The thermocouple with pocket and spring loaded DIN insert assembly comprises a 316 stainless steel pocket which can be either fabricated or drilled from solid fitted with a terminal head. Fitted inside is a spring-loaded insert, the thermocouple sensor can be fitted with your choice of terminal block or transmitter.
The spring-loading ensures that the tip of the sensor makes contact with the inside of the thermocouple pocket giving the best thermal transfer and therefore response and accuracy. All wetted parts of the probe are manufactured from 316 stainless steel.
Fabricated pockets are TIG welded and solid drilled thermowells are gun-drilled for the best concentricity and strength. Although commonly supplied with threaded connections, this style of probe can also be supplied with flanged or hygienic connections.
We stock a variety of terminal heads that cover all eventualities. The most popular is the aluminium alloy KNE head which is commonly used in the industry. 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.
As a UK sensor manufacturer, 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.
Additional Information About Spring Loaded Temperature Sensor
The spring loaded temperature sensor is also available as an PPL8 RTD/PRT sensor. We are also able to supply the thermocouple probe with your choice of thermistor sensor.
We offer a comprehensive calibration service and a wide variety of accessories.
Our PPL8-T temperature sensor is made to order based on your process in the UK. If you’d like more information on any of our sensors, or a free quote, please contact us.
What is a Spring Loaded Thermocouple?
A spring loaded thermocouple is a type of temperature sensor. It consists of two different metal wires joined together. The thermocouple working principle is designed with a spring mechanism that allows it to apply pressure when placed on a surface, ensuring good contact for accurate temperature measurement. A spring loaded temperature sensor is commonly used in industrial applications to monitor and control temperature.
