b) Cold or Reference Junction: The other metal is connected to a body of known temperature. This means that the thermocouple measures unknown temperature of the body with reference to the known temperature of the other body. Thermocouples can measure a wide range of temperatures and they are se...
makes it straightforward to visualize the test flow and hence verify and debug the terminal’s behavior. Tests can be annotated, enabling easy identification of logical and functional blocks so that they may be re-used by “cutting and pasting” into a new test if required. Test flow is ...
Use niDMM Error Message to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI ran or FALSE (...
A Pt100/Pt1000 RTD is a type of temperature sensor. It consists of an element that uses resistance to measure temperature. Often platinum is used for the element which is the reason why they are often called platinum resistance thermometers (P...
RTDs could detect temperatures of up to 1000°C. However, it’s challenging to obtain precise readings at temperatures higher than 400°C. TCs can measure up to 1700°C. The recognized rule is: for precision, use an RTD for temperatures below 850°C; for temperatures beyond 850°C, use ...
In cases where numerous signal converters and other devices are mounted on a rack or panel, the CA51/CA71 can be used to check the input and output signals of each device, while simultaneously checking the power supply. There is no need for a separate multimeter to measure supply voltage....

What is the difference between and a resistance temperature detector (RTD) and a thermocouple? Both RTDs and thermocouples are sensors used to measure heat in scales such as Fahrenheit and Kelvin. Such devices are used in a broad range of applications and settings, often presenting people with ...
They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability. The RTD is one of the most accurate temperature sensors. Not only does it provide good accuracy, it also provides excellent...
By measuring this voltage, you can determine its resistance and that's how its temperature. The relationship between resistance and temperature is relatively linear. Typically, RTDs have a resistance of 100 Ohm at 0 °C and can measure temperatures up to 850 °C....
