Technical Learning
Measuring temperature and humidity in warehouses, etc.
Do you need to monitor temperature or humidity at different locations in your warehouse, production hall, archive or perhaps in a museum? Do you want to have an up-to-date overview of all measured locations in one place? Do you need to monitor temperature or humidity exceeding a specified range? Do you not want to interfere with the building structure by installing cabling and do you require reliability?
Then it is necessary to deploy a suitable measuring system that guarantees simple installation and reliable wireless connection of sensors. Our measuring system meets exactly these requirements...
Differences Between 2, 3, and 4-Wire RTDs
Resistance Temperature Devices (RTDs) are widely used in industrial and commercial applications due to their accuracy and stability. However, RTD wire configuration can significantly impact measurement precision. Selecting the right configuration ensures optimal performance, minimizes errors, and enhances system reliability.
RTDs are typically manufactured in three different wiring configurations: 2-wire, 3-wire, and 4-wire. Each configuration is designed to compensate for lead wire resistance to varying degrees, impacting measurement accuracy. The 2-wire setup is the simplest but most susceptible to errors...
