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). The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature.
A resonant-tunneling diode (RTD) is a diode with a resonant-tunneling structure in which electrons can tunnel through some resonant states at certain energy levels. The current–voltage characteristic often exhibits negative differential resistance regions.
RTD may refer to: Science and technology. Real-time data; Residence time distribution; Resonant-tunneling diode; Round-trip delay time, in telecommunications;
The Callendar–Van Dusen equation is an equation that describes the relationship between resistance (R) and temperature (T) of platinum resistance thermometers (RTD). As commonly used for commercial applications of RTD thermometers, the relationship between resistance and temperature is given by the following equations.
The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.
For most people, Thanksgiving isn’t complete without a whole roasted turkey. Golden brown and glistening, it’s often the centerpiece of the meal. And, if done right, it can be — dare we say ...
Those ever-present TV drug ads showing patients hiking, biking or enjoying a day at the beach could soon have a different look: New rules require drugmakers to be clearer and more direct when ...
RTD replaced the major predecessor public agency, the Los Angeles Metropolitan Transit Authority, and took over eleven other failing bus companies and services in the Southern California region. [7] RTD was placed in charge of creating a heavy rail public transportation system for Southern California, and for planning for bus improvements.
