Thermometer resistance
WebbNickel resistance thermometers are standardized by the German Standard DIN 43760. As opposed to platinum, nickel has a higher temperature coefficient (alpha= 6,17E-03) which, compensating for its lower electrical resistivity, makes its sensitivity comparable to that of platinum thermoresistances. 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, … Visa mer Common RTD sensing elements for biomedical application constructed of platinum (Pt), nickel (Ni), or copper (Cu) have a repeatable [b] resistance versus temperature relationship (R vs T) and operating temperature range. … Visa mer The three main categories of RTD sensors are thin-film, wire-wound, and coiled elements. While these types are the ones most widely used in … Visa mer The advantages of platinum resistance thermometers include: • High accuracy • Low drift Visa mer Two-wire configuration The simplest resistance-thermometer configuration uses two wires. It is only used when high accuracy is not required, as the resistance of the connecting wires is added to that of the sensor, leading to errors of … Visa mer To characterize the R vs T relationship of any RTD over a temperature range that represents the planned range of use, calibration must be … Visa mer Resistance thermometers are constructed in a number of forms and offer greater stability, accuracy and repeatability in some cases than … Visa mer These elements nearly always require insulated leads attached. PVC, silicone rubber or PTFE insulators are used at temperatures below about 250 °C. Above this, glass fibre or ceramic are used. The measuring point, and usually most of the leads, require a … Visa mer
