From RS Pro a high-quality and reliable Pt100 PRT (Platinum Resistance Thermometer) or RTD (Resistance Temperature Detector). This Pt100 RTD has a sensing element that is encased in silicone rubber patch so it can be used to measure the temperatures on surfaces. The 4 cores have a durable and flexible PFA outer jacket. This platinum resistance thermometer provides accurate and reliable temperature measurement for a wide range of applications.

An RTD is a type of temperature sensor based on the correlation between metals and temperature. As the temperature of a metal increases so does its resistance to the flow of electricity. This resistance can be measured and converted to a temperature reading. In a Pt100 RTD, the ’Pt’ stands for platinum (platinum wire or film) and ’100’ means that the temperature sensor has a resistance of 100 Ohms at 0°C. Platinum is the most reliable metal due to its linear resistance to temperature relationship over a large temperature range.

A Pt100 silicone patch sensor is designed to measure the temperature on surfaces. The temperature sensor element is embedded inside a silicone patch. One side of this patch has a self-adhesive aluminium foil backing allowing the sensor to be stuck firmly in place. The other end of the sensor is terminated by 4 wire tails which are connected to the temperature measuring equipment.

These Pt100 PRT silicone patch sensors with their compact and versatile design are most commonly used in pipe or surface measurement.
