Item# (PN): PR-16 Shipping and Payment
The PR-16 series, Omega's economical RTD handle probe, features an easy-grip molded handle. It has a 3-conductor retractable cable that is 1 foot long, expandable to 5 feet. Pt100 is available in standard lengths of 12, 18 and 24". The 12" length probe can be stored in toolboxes or other locations for easy access. Standard Pt100 termination is stripped-end lead wires. This comes with either Pt100 Ω or Pt1000 Ω element.
The online configurator may not contain all available options. If you do not find what you are looking for, please contact us.
Comes with bare stripped ends as standard. You can order the probe, including the installation of connectors. Put the required connectors in the basket together with the probe. If needed, order the required connectors separately, see "Related Products" below.

RTD Pt100 vs Thermocouple
It is not practical to compare RTDs (Pt100 and others) and thermocouples generally. However, if we compare their performance in terms of specific criteria, we can see which is best suited for specific applications. Thermocouples are best for working at high temperatures. New manufacturing techniques have improved the measurement range of RTD probes, but more than 90% of RTDs are designed for temperatures below 400°C.
In contrast, some thermocouples can be used at up to 2500°C. Thermocouples are generally cheaper than RTDs...
Origin Story of the RTD / Pt100
The same year (1821) that Thomas Seebeck made his discovery about thermoelectricity (Seebeck effect, see thermocouples), Sir Humphrey Davy announced that the resistivity of metals showed a marked temperature dependence. Fifty years later, Sir William Siemens proffered the use of platinum as the element in a resistance thermometer. His choice proved most propitious, as platinum is used to this day as the primary element in all high-accuracy resistance thermometers, Pt100, Pt1000 etc.
In fact, the Platinum Resistance Temperature Detector, or RTD Pt100, is used today as an interpolation standard from the oxygen point (-182.96°C) to the antimony point (630.74°C)...
What are RTD temperature sensors?
RTDs or Resistance Temperature Detectors, are temperature sensors that contain a resistor that changes resistance value as its temperature changes. The most popular RTD is the Pt100. They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability.
Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is usually quite fragile, so it is often placed inside a sheathed probe to protect it...
