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 is capable of isolating, amplifying, linearizing and filtering noise from the temperature sensor signal.

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.
