Platinum Resistance Thermometer with Pocket and Spring Loaded DIN Insert
The PRT temperature sensor provides high-quality temperature measurement whilst allowing the sensor to be easily replaced in the shortest possible time and with minimal effort.
The 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 which 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 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 thermowell 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.
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.
All temperature sensors at Process Parameters are designed and custom-built to your specifications, and manufactured in the UK.
The PPL8 is also available as a thermocouple PPL8 sensor. We are also able to supply the probe with your choice of thermistor sensor.
At Process Parameters, we offer a comprehensive calibration service and a wide choice of accessories such as compression fittings, signal conditioners, pockets/thermowells and extension cables.
The temperature sensor is suitable for the measurement of liquids and gases across a wide temperature range.
