RTD Pt100 Probe Platinum Resistance Thermometer, PTFE Lead (-50 to +250°C)
The RTD probe PPL1-P temperature sensor is suitable for the measurement of liquids and gases across a wide temperature range of -50 to +250°C. The 3-wire class thermocouple sensor gives excellent accuracy across the full measuring range.
The plain stem of the probe is made from 316 stainless steel and the tip is TIG welded closed to give a pressure-tight housing for the platinum resistance thermometer. We offer standard diameters of 3mm and 6mm in various standard lengths to suit your needs. The 3mm sensors have a pot seal to accommodate the cable.
The flying temperature lead sensor is fitted with 2 metres of high-performance PTFE (Teflon) screened lead which is practically chemically inert and is suitable for the full operating range of the sensor. The plated copper braid screen provides mechanical protection as well as providing the opportunity for electrical screening should it be required.
Additional Information about RTD Temperature Sensor
RTD Pt100 probes, also known as platinum resistance thermometers, offer high accuracy in temperature measurement due to their precise temperature coefficient of resistance tolerance.
These probes employ a sensing element made of platinum, which changes its electrical resistance predictably with temperature changes. The Pt100 is the most common RTD element type, calibrated at 0°C (32°F) to a resistance value of 100 ohms.
With a wide measurable temperature range from -50°C to +250°C and standard tolerance classes, our Pt100 probes provide reliable temperature readings across various applications.
However, the PTFE lead wire used in this particular model may exhibit a slightly wider tolerance band, resulting in less accuracy compared to higher-grade RTD probes. Nonetheless, Pt100 probes remain a preferred choice for their high accuracy and stability in temperature measurement tasks.
The PPL1-P is ideal for use with compression fittings or our PPL50-TW pocket making them easy to install in your process. The PPL1 RTD probe with PTFE lead is available as a thermocouple PPL1 sensor, and we’re also able to supply the RTD probe with your choice of thermistor sensor.
We offer an in-house comprehensive calibration service and a wide variety of accessories. Have a look at our other RTD Pt100 sensors, and platinum resistance thermometers.

FAQs
What is an RTD Temperature Probe?
An RTD temperature probe is a sensor used to measure temperature. RTD stands for Resistance Temperature Detector. It consists of a wire made of a material whose resistance changes with temperature. By measuring the resistance of the wire, the temperature can be determined accurately and reliably.
What is a Pt100 Probe?
What is a PTFE Lead?
A PTFE lead refers to a lead or wire that is insulated with PTFE (polytetrafluoroethylene) material. PTFE is a type of fluoropolymer known for its excellent electrical insulation properties and high resistance to heat, chemicals, and moisture.
PTFE leads are commonly used in various applications, including electrical and electronic industries, where reliable and durable insulation is required for transmitting signals or power while maintaining protection against external factors. The PTFE insulation ensures good electrical performance and flexibility while offering resistance to harsh environments.
