RTD Sensor Resistance Thermometer with Fixed Process Connection & Lead
The PT100 RTD sensor is suitable for the measurement of liquids and gases across a wide temperature range. All of our temperature sensors are designed and custom-built to your specifications.
The plain stem of the RTD probe is made from 316 stainless steel and the tip and the fitting are TIG welded to give a pressure-tight housing for the sensor and your application. Many metric and imperial probe diameters are available from 2mm upwards. Threads are generally BSP or NPT but we can supply others to your requirements such as Metric, UNF etc.
We stock a range of cables for use in our sensor manufacturing from low-cost PVC to high-performance PTFE (Teflon) and high-temperature glass fibre insulations. We can cover almost any requirement whether this is low or high temperature or other environmental considerations such as moisture ingress protection or protection against corrosive substances.
Other optional extras include pointed tip probes for insertion into semi-solids such as food, reduced diameter sensing tips for improved response times and pre-bent probes to fit your application perfectly.
A – PVC/PVC Screened (-10 to +105°C)
B – Silicone Rubber Unscreened (-60 to +180°C)
C – PTFE/PTFE Screened (-200 to +250°C)
D – Glass Fibre Stainless Steel Overbraid (0 to 350°C)
(Other cables available upon request).
Additional Information about PRT Sensor
The PPL2-P is ideal for installation directly into your process or with our PPL51-TW pocket. The PPL2 flying lead sensor is also available as a thermocouple PPL2 sensor. We are also able to supply the probe with your choice of thermistor sensor.

FAQ about RTD Sensors & Probes
What is an RTD sensor probe?
An RTD sensor, also known as a Resistance Temperature Detector, is a type of temperature sensor that operates on the principle of changes in electrical resistance with temperature. RTD sensors are commonly used for temperature measurement in various industrial and scientific applications.
RTD sensors consist of a resistive element made from pure metals, such as platinum, nickel, or copper, which exhibit a predictable change in resistance with temperature. Platinum is the most commonly used material due to its high accuracy and stability over a wide temperature range. The resistive element is typically wound into a coil or formed into a thin film on a ceramic substrate.
