Flow temperature integrated transmitter

Product Overview

The NK500C series flow temperature integrated transmitter can monitor the liquid flow and temperature situation in pipelines in real time, provide flow alarm switch output, temperature 4-20mA signal or switch output, and use LED digital display to show the current temperature and flow rate. It can also set alarm contact output through the header to achieve integrated monitoring of temperature and flow in pipelines. Widely used in industries such as hydropower plants, petrochemicals, electricity, metallurgy, steel mills, papermaking, food processing, water treatment, battery factories, etc.

Working Principle

The NK500C series flow temperature integrated transmitter is a temperature transmission controller installed on the basis of a thermal conductivity flow switch (which is designed based on the principle of heat exchange), and achieves temperature flow integrated monitoring function through LED digital display.

The probe is equipped with a built-in heating module and a thermal sensing module, and the thermal conduction of the flow switch is closely related to the flow rate of the medium. When measuring, heat is generated by the heating module. If there is no medium flowing in the pipeline, the heat received by the heat sensing module is a fixed value; When a medium flows, the heat received by the thermal module will vary with the flow rate of the medium. The thermal sensing module converts this temperature difference signal into an electrical signal, which is then converted into a corresponding standard analog signal or contact signal output by the processor. The flow switch displays and controls the flow rate of the medium through this signal.
