RTD Temperature Transmitter for 2-wire, 4 to 20-mA Current Loop Systems (TIDA-00095)

This comprehensive design provides a complete system that measures and processes temperature signals inputs from 2-wire, 3-wire, and 4-wire resistance temperature detectors (RTDs) and outputs a 4 to 20-mA current-loop signal corresponding to the temperature processed from the RTD inputs. It is intended as a reference design for process measurement applications in factory automation, field transmitters and building automation. With less than 0.17°C maximum measured error over -200°C to 850°C, extremely low loop power consumption 1.4mA (typical including RTD biasing currents) and IEC61000 pre compliance testing, this design significantly reduces the design time for development of high accuracy temperature transmitter systems. It also addresses system level calibration - both offset and gain that can be implemented to improve ADC and DAC accuracy as well as also includes linear interpolation to address the non-linearity of the RTD element.

Возможности

Input Compatible with 2-, 3-, and 4-wire RTD Probes Low power consumption of 1.4 mA (with RTD biasing currents) makes it ideal for loop powered systems 4-20 mA current-loop signal output with 0.25 µA resolution Maximum measured error: 0.11°C (-200°C to 200°C), 0.17°C (-200°C to 850°C) IEC61000-4-2: ESD: Air Discharge: ±8 kV Class A, Contact Discharge ±4 kV Class A IEC61000-4-4: EFT: ±2 kV Class A
