The Pt 1000 sensor is the "big brother" of the Pt 100 sensor. Its nominal resistance at 0°Cis 1000 Ω. Resistance values of the whole series are higher by a factor of 10. The sensor
is used in the same way as the Pt 100 sensor. Its dimensions are slightly larger (4 x 5
uninsulated). Thermostats and sensors for Pt 1000 on request.
A Pt100 temperature sensor is a type of resistance temperature detector (RTD) that uses platinum as a sensing element. It has a resistance of 100 ohms at 0 degrees Celsius and its resistance changes with temperature. Pt100 sensors are commonly used in industrial applications due to their high accuracy and stability over a wide temperature range.
The force between two charges is inversely proportional to the square of the distance between them. This means that as the distance between the charges decreases, the force between them increases, and vice versa.
The distance between objects and the different is 0. The distance between the mass and an object is 1.
The force of gravity between two objects will increase if their distances decrease. The force of gravity or proportional to the objects' masses, and inversely proportional to the square of the distance between them.
A contrast between what is expected and what happens is called irony. Irony involves discrepancies between what is said and what is meant, or between what is expected and what actually occurs.
A PT100 is a PTC (Positive Temperature Coefficient), which means that it's resistance ascends with it's temperature
A PT100 is a resistor; more precisely said it's a PTC (Positive Temperature Coefficient), which means that it's resistance ascends with it's Temperature. The term "PT100" is used because PT100 are made out of Platinum (symbol: Pt)and it's resistance is 100Ω at a Temperature of 0°C or 273,15K. Because of this feature they are used as sensors by measuring the Ω and determine the consequent Temperature.

To check if RTD PT100 is working properly you need to check and make sure all the wires are connected. Take several readings and if they are the same, it is working properly.

The 'P' stands for "PLUS". The PT100P (or "PT100 Plus") model has an expanded magazine capacity. Its magazines hold 16 rounds of .40 S&W, while the original regular PT100 magazines only hold 11 rounds. The magazines for the two models are not compatible with each other. The PT100P 16-round magazines are wider than the older PT100 11-round mags.

If the resistance is 100 Ω and you use PT100, the temperature is O°C or 273.15K.
IAS - Indian Administrative Service where as ICS - Indian Civil Service. ICS were and are known as collectors. There are examinations held for IAS which is divided into preliminary exam, main exam and an interview. ICS was introduced by Lord Cornwallis, where as IAS was started after independence. ICS was practiced till independence
If you are referring to a Pt100, the resistance at 0°C is 100 ohm. At 100°C it is 138.5 ohm. In between the relation is not a linear one, and there is no formula, other than a polynome, to describe the relation. Look at http://www.jensenelectric.dk/extern/pt100din.htm for more information.
What is a thermocouple?Let's split the word: 'thermo and couple'. This means that it has to do with temperature and a couple (two).In the 19th century Mr Seebeck discovered that there was an electrical current flowing through a couple of metal wires (of different material) when they where joined at the two ends and if the two ends where at different temperature. This meant that if you could measure the current and the temperature of one end, you could calculate the temperature at the other end.In earlier times the temperature of the first end (the reference junction) was kept at melting ice temperature (called the cold junction). Nowadays we measure the temperature of the reference junction electronically, do some calculations and display the result.Two things on thermocouples must be said: first of all depends the relation between electrical current and temperature difference on the different metals used in the two wires and secondly it is absolutely non linear. From the first remark follows that there are different types of thermocouples (for different applications and ranges). So make sure that you have a thermocouple and an instrument for the same thermocouple type. Out of the second remark we learn that the mentionned calculations can compensate only partially with the linearity errors, which restricts the accuracy.What is a Pt100?As for the thermocouple, we split the word: Pt and 100. Pt is the chemical symbol for Platinum, 100 is the resistance in Ohm of the Pt100 at 0 °C. The resistance changes (fearly linear) with temperature are: 0.385 Ohm/°C for European and 0.392 Ohm/°C for American elements. So, by measuring the resistance we can calculate the temperature. Never use a European Pt100 with an American instrument unless you know that it is set for the right conversion factor (usually called 'alpha'). In english a Pt100 is also called a RTD element, meaning Resistance Temperature Detector.
An RTD or Pt100 sensor is connected with two, three or four wires to the measuring device.we learned that we are in fact measuring resistance to determine the temperature. Now when measuring the resistance of the sensing element, we also measure the resistance of the leads and cables used. This gives an error! To compensate for this, the three wire type (bridge) is used, giving enough accuracy in most industrial applications. Even better accuracy is possible with a four wire Pt100 (laboratory applications). Our Pt100 panel mounted indicators have an offset compensation when using two wire sensors.
