RTD may refer to:
Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature by correlating the resistance of the RTD element with temperature. 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. The RTD element is made from a pure material, typically platinum, nickel or copper. The material has a predictable change in resistance as the temperature changes and it is this predictable change that is used to determine temperature.
They are slowly replacing the use of thermocouples in many industrial applications below 600 °C, due to higher accuracy and repeatability.
Common RTD sensing elements constructed of platinum, copper or nickel have a repeatable resistance versus temperature relationship (R vs T) and operating temperature range. The R vs T relationship is defined as the amount of resistance change of the sensor per degree of temperature change. The relative change in resistance (temperature coefficient of resistance) varies only slightly over the useful range of the sensor.
RTD - Resistance Temperature Detector - Temperature Sensor 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 ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum, nickel, or copper. The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature. As RTD elements are fragile, they are often housed in protective probes. RTDs, which have higher accuracy and repeatability, are slowly replacing thermocouples in industrial applications below 600 °C . In this video we learn about of Resistance Temperature Detector or RTD. More videos:- Sensor │...

Temperature is the most measured parameter in the process industry. This video explains the measuring principle of Pt100 thin-film sensors, which are primarily used. It also provides hints for installation in the process and describes the evaluation of the signals using temperature transmitters and displays. 4:35 minutes http://bit.ly/29VYfTJ
Dumb Ways to Die 3:06 minutes Denver’s Regional Transportation District (RTD) is bringing you Dumb Ways to Die, for first time in the United States. These guys are funny, but RTD takes safety seriously. In 2013, Metro Trains Melbourne launched Dumb Ways to Die, a safety awareness campaign that uses humor to have a serious conversation about safety. During their campaign, Metro Trains Melbourne has received over 75 million pledges worldwide from people committed to being safe around trains. At RTD, your safety is our number one priority. Please take a lesson from our colorful friends and be safe around buses and trains. It could save your life.
This is a brief overview of how a three wire RTD compensates for the natural resistance of the wires that it's made of. This video shows a formula. This video explains how resistance can be compensated for when trying to determining temperature and using a 3 wire rtd.

You know you're livin' a lie when you just can't win
Pulling in first prize ain't gonna give you a break
You know I'm kickin' back, I had a broken wing
Me and my shadow are the next best thing
I need someone
You know it might take more than you give to me
Are you gun-shy, are you listening?
What we got here is dead reckoning
And take me in for the night in the right time zone
We'll do what you like, make a left turn home
I put out the light, you're turnin' way too red
No stop sign straight up ahead
You need so much
So much sympathy
That's more than I can say
You know it's not too late
Are you gun-shy, are you listening?
What we got here is dead reckoning
And if it feels good, we'll do it again
See your way clear, dead reckoning
Tell me why, tell me why
Are you listening?
Are you listening?
Are you listening?
Are you listening?
You mean so much
So much to me
That's more than I can say
You know it's not too late
Are you gun-shy, are you listening?
What we got here is dead reckoning
And if it feels good, we'll do it again
See your way clear, dead reckoning, yeah
What we got here is dead reckoning
