Difference between DIN and JIS
Hi, all. I'd like to know the difference between DIN and JIS for a PT100 resistance thermometer. When using it with a digital temperature controller (Honeywell 1000 series), the controller asks for the type of RTD. How do I find out?.
Expert’s answer: Difference between DIN and JIS
Hi! To sum it up, you want to know the difference between DIN and JIS. Here, we have different types of standardization. DIN is the German Institute for Standardization, and JIS is the Japanese Industrial Standards. Usually, when you buy a new resistance temperature detector (RTD) from a manufacturer, you can choose which standard you want. Subsequently, when you configure a temperature transmitter or a control system, you need to know which standard your sensor follows.
When we talk about the JIS standard, the temperature coefficient is 0.003916 ohm per degree Celsius. The DIN standard has a value of 0.00385. Both calibrate to 100 ohms at 0 degrees Celsius (32 degrees Fahrenheit). Before configuring, make sure you have the right temperature coefficient for your standard. Also, remember that the market has more standards than those two.

Temperature loop transmitter?
A temperature loop system is receiving all information from the field directly into the PLC without a transmitter, which means that PLC is reading the RTD and thermocouple directly. So, is there any advantage to applying a transmitter in the field?
