Temperature transmitters
What is a temperature transmitter?
A temperature transmitter converts the small signal from a temperature sensor - typically a thermocouple or RTD - into a more robust 4...20 mA or digital signal for interfacing into other control equipment. To ensure accuracy, a temperature transmitter converts the signal from a temperature sensor—typically an RTD or thermocouple—into a more robust and standardized output. This output may be analog (such as 4–20 mA) or digital, using protocols like HART, PROFIBUS PA, or FOUNDATION Fieldbus. The signal conditioning process includes isolation, amplification, linearization, and noise filtering to ensure reliable data transmission.

RTD vs TC: Choosing the right sensor
When choosing between RTD vs TC, it's important to understand their unique advantages. RTD sensors are ideal for precise temperature measurement in stable environments, offering excellent long-term accuracy. They are commonly used in food production, HVAC systems, and pharmaceutical manufacturing. Thermocouple sensors, with their ability to measure extreme temperatures, are better suited for high-temperature applications, such as in oil and gas or metal processing. Both sensor types are fully supported by our temperature transmitters, ensuring optimal performance for any application.
