• Process control involves measuring variables such as temperature, pressure, and flow rate.

• Control systems use this data to adjust process parameters and maintain optimal conditions.

• Examples include controlling the temperature in a chemical reactor or the flow rate of water in a pipeline.

• Process control is essential for ensuring product...read more

RTD stands for Resistance Temperature Detector.

• RTD is a type of temperature sensor that measures temperature by correlating the resistance of the RTD element with temperature.

• It is commonly used in industrial applications where accuracy and stability are important.

• RTDs are made of pure metals or alloys with a known temperature-resistance relationship, such as platinum.

• They provide accurate and reliable temperature meas...read more

RTDs and thermocouples are both temperature sensors, but they differ in terms of principle, accuracy, range, and cost.

• RTD stands for Resistance Temperature Detector, while thermocouple is a temperature sensor based on the Seebeck effect.

• RTDs are more accurate and have a higher temperature range compared to thermocouples.

• RTDs are more expensive than thermocouples.

• RTDs have a linear relationship between resistance and te...read more
