PT1000 sensors are the second most common type of platinum resistance thermometer. Often resistance thermometers are generally called PT1000 sensors, even though in reality they may not be the PT1000 type. Pt refers to that the sensor is made from Platinum (PT). 1000 refers to that at 0°C sensor has a resistance of 1000 ohms (Ω). PT1000 sensors are used over PT100 sensors in two wire applications as PT1000s make lead resistance less significant.

RTD sensors with thermowells are designed for processes where corrosion, pressure, abrasion or shear force may threaten the life of the element. Thermowells, machined from a solid bar stock or fabricated from a pipe, shield the RTD element from external aberrations. Fabricated thermowells offer a lower cost alternative and are used in applications where high pressure is not a consideration.

Platinum RTDs (Resistance Temperature Detectors) are sensing elements that are made of pure platinum wire coil (wire wound) encapsulated in ceramic or glass, or a thin film platinum deposited on a ceramic substrate. Platinum RTDs have a positive temperature coefficient. The electrical resistance increases as temperature rises in a known and repeatable manner. Their linearity and unmatched long term stability firmly establish platinum RTD elements as an ideal sensor for most industrial applications.
