From RS Pro a high-quality and reliable Pt100 PRT (Platinum Resistance Thermometer) or RTD (Resistance Temperature Detector) sensing probe. This RTD probe has a robust construction with the sensing element encased in a rigid 316 stainless steel sheath. The leads have a durable and flexible silicone rubber insulation. This platinum resistance thermometer provides accurate and reliable temperature measurement for a wide range of applications. What is an RTD? 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 Ohm at 0°C. Platinum is the most reliable metal due to its linear resistance to temperature relationship over a large temperature range. What is a Pt100 Probe? A Pt100 probe is the most rugged form of RTD. The Pt100 sensor element is mounted inside a metal sheath or probe. This protects it from being damaged by the surrounding environment when it is inserted into the process to be measured. The other end of the probe is terminated by an insulated lead comprising of 4 wire tails which are connected to the temperature measuring equipment. High stability sensing element with a precision output • IEC 60751 Class B accuracy/tolerance • 4 lead wires for accurate readings • Leads connect to any 2 3 or 4 wire PT100 instrument • Rigid 316 corrosion resistant stainless steel sheath for protection of sensing element
