Wire-wound RTDs (especially the inner-coil type) are the most accurate type of RTD. Those with glass cores can readily be immersed in many liquids, while those with ceramic cores can be used to accurately measure extremely high temperatures.

A single RTD Pt100 platinum coil element mounted inside a ceramic tube down to 1.0mm diameter or 8mm long minimum. Accuracies from class B (W0.3) down to 1/10DIN (W0.03) are available.

Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper (Cu).

Platinum-based RTDs are laser-trimmed for accuracy and flexibility. They are designed to offer stable and fast linear outputs. Accurate and interchangeable, the RTD temperature sensors have plastic or ceramic, miniaturized or surface mount housings (including printed …

The 634F series high temperature ceramic RTD probe is encapsulated in a ceramic, aluminum oxide tube which protects the sensor from impact damage and is ideal for use in high temperature applications.

May 15, 2018 · OMEGA RTD elements can be used for a variety of temperature applications. Models are available for temperature ranges as broad as -200 to 850°C. Dual element RTDs are also available for applications where two different instruments need to …

Wire-wound and thin-film ceramic RTD elements deliver accurate, reliable and repeatable temperature measurement over a wide temperature range. Minco ceramic elements provide excellent shock and vibration resistance when assembled into probes or potted directly into heat sinks and housings.

Thin-film RTDs are platinum elements that are constructed by placing a sensing platinum layer over a ceramic substrate, covered with passivation glass layers. This results in excellent shock …

spring-loaded insert RTD (Resistance Temperature Detector) with a ceramic block is a temperature sensor designed for use in applications where the sensor needs to be inserted into a thermowell or protection tube. The sensor consists of a sheathed RTD element, which is inserted into a ceramic block.

RTD sensors are specifically useful where linearity, accuracy, interchangeability, and repeatability are essential. Resistance temperature detectors are powered devices that sense changes in resistance and display temperature in °F or °C.
