Microcyber Corporation at Hannover Messe 2023 to introduce more details of Fieldbus, Profibus and HART equipment and technology.

Temperature transmitters are devices used to measure temperature and convert it into standard output signals. Their technical specifications typically include the following aspects

Microcyber presented fieldbus and industrial wireless products at the exhibition.

NCS-TT108 smart temperature transmitter, using the fieldbus technology, is a new generation of smart fieldbus temperature transmitter and it is an indispensable field device for process control. NCS-TT108 transmitter integrates abundant function blocks and realizes not only general measurement function but also complicated control strategy.

The role of temperature in the transmitter For the temperature range of the temperature transmitter, usually a transmitter will calibrate two temperature ranges, that is, the normal operating temperature range and the temperature compensable range. The normal operating temperature range refers to the temperature range when the transmitter is not damaged under working conditions. When the temperature compensation range is exceeded, the performance index of its application may not be achieved. The temperature compensation range is a smaller range than the operating temperature range. typical range. Working within this range, the transmitter will definitely achieve its due performance.

As a key member of the FieldComm Group (FCG) and PROFIBUS & PROFINET International (PI), we are committed to driving the standardization and adoption of advanced fieldbus technologies (FF, Profibus, HART, WirelessHART) worldwide.

This document aims to provide system engineers, hardware developers, and prgject decision-makers in the field of industrial automationwith a full-stack technology guide covering chip selection, hardware design. protocol stack development, and system integration.t helpslocal enterprises build independent and controllable HART technology capabilities.

The core challenge of HART hardware design lies in how to simultaneously carry a 4-20 mA DC analog signal, a 1200/2200 Hz FSK AC signal, and possible loop supply voltage on the same pair of wires, ensuring that the three do not interfere with each other and meet stringent industrial EMC standards. This chapter starts with the system architecture and analyzes the design key points layer by layer.

In the field of industrial automation, HART (Highway Addressable Remote Transducer) protocol serves as a core technological link connecting traditional analog equipment with modern digital management systems. Having undergone nearly forty years of industrial field validation, HART has become one of the most widely deployed field device communication protocols globally. By using Bell 202 FSK modulation technology, digital communication signals are superimposed on a traditional 4-20mA analog current loop, achieving dual-mode coexistence of " analog transmission + digital communication . " This design allows companies to endow existing equipment with digital capabilities such as remote configuration, real-time diagnostics, and multivariate transmission without interrupting existing control loops or re-laying cables.
