intelligent temperature transmitter adopts field bus technology, is a new generation of intelligent temperature transmitter, is an indispensable field device in process control. The device integrates a wealth of functional modules, which can achieve both general detection functions and complex control strategies.

According to the recent reader survey of Control Engineering Chinese Edition and CONTROL ENGINEERING in the United States, the application and development of industrial Ethernet technology show the following seven trends

By analyzing the needs of users, we can roughly divide the technical requirements and expectations of users on the fieldbus into the following three levels:

APC3 is a fieldbus dedicated chip for the development of PROFIBUS DP intelligent slaves, supporting the complete DPV0 protocol. APC3 is fully compatible with SPC3LV and VPC3 working in DPV0/3.3V/1.5K dual-port RAM mode.

NCS-TT105 supports HART, FF, and PA protocols. It can be widely used in the petroleum, chemicals, electricity, and metallurgical industries, etc.

HART temperature board MS0210, using the fieldbus technology, is a new generation of smart temperature module and it is an indispensable field device for process control. It can be widely used in the petroleum, chemicals, electricity, and metallurgical industries, etc.

Temperature Transmitters

A temperature transmitter is an instrument that converts a temperature variable into a transmittable standardized output signal, and is mainly used for the measurement and control of industrial process temperature parameters. The current transmitter converts the AC current of the main circuit under test into a standard signal of constant current loop, and sends it to the receiving device continuously.

The temperature transmitter is mainly used for temperature measurement, and the following aspects should be paid attention to when selecting models.

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.
