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 with 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.

Which PR electronics temperature transmitters support the HART 7 protocol, and what advantages does it provide?
HART 7 is supported by multiple series including the PR 5437 (A/B/D), PR 6437 (A/D), PR 7501 (field-mounted), PR 3113, and PR 3337. HART 7 enables bidirectional digital communication superimposed on the 4-20 mA analog signal, allowing remote configuration, diagnostics, and multi-variable data access without interrupting the process signal. Compared to HART 5, HART 7 offers faster communication, burst mode, and enhanced device descriptions.
What sensor types can PR electronics temperature transmitters accept as input?
PR electronics transmitters support a wide range of sensor inputs. RTD types include Pt10 through Pt10000, Ni10 through Ni10000, and Cu5 through Cu1000. Thermocouple types include B, E, J, K, L, N, R, S, T, U, W3, W5, and LR. Additionally, many models accept linear resistance (0-100 kΩ), bipolar millivolt signals (-800 to +800 mV), and potentiometer inputs. The PR 5437A, for example, accepts all these input types in a single unit, reducing spare part inventory.
What is the operating temperature range for PR electronics head-mounted temperature transmitters?
The PR 5437A and PR 6437A head-mounted transmitters operate from -50°C to +85°C in standard mode and -40°C to +80°C in SIL-rated mode. The field-mounted PR 7501 operates from -40°C to +85°C. The DIN-rail mounted PR 3100 series (e.g., 3101, 3102) operates from -25°C to +70°C. Storage temperature for head-mounted models is -50°C to +85°C. These wide operating ranges make PR electronics transmitters suitable for extreme industrial environments.
