DIN and JIS are different kinds of standardization: DIN is short for Deutsche Institut für Normung, or the German Institute for Standardization. JIS stands for Japanese Industrial Standards.

Usually, when you buy a new resistance temperature detector (RTD) from a manufacturer, you can choose between DIN and JIS standards. Subsequently, when you configure a temperature transmitter or a control system, you need to know which standard your sensor follows.

DIN and JIS standards

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?
