Our PPL3-T thermocouple sensor is a general purpose probe with a choice of terminal housings for use in many applications. It is suitable for the measurement of liquids and gases across a wide temperature range. All sensors are made to order so it is generally possible to meet all of your requirements.
The plain stem of the probe is made from 316 stainless steel the tip is TIG welded closed to give a pressure tight housing for the sensor. The fitting into the terminal housing is also normally welded rather than being a compression fitting. Many metric and imperial probe diameters are available from 2mm upwards.
We stock a variety of terminal heads that cover all eventualities. The most popular is the aluminium alloy KNE head that 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 the 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 intrisically safe transmitters or those with HART protocol. We can also fit in head displays if required.
The PPL3-T is ideal for use with compression fittings or our PPL50-TW pocket making them easy to install in your process. The PPL3 is also available as a Resistance Thermometer sensor. We are also able to supply the probe with your choice of thermistor sensor.
