VOLKE FGS Stable high quality thermal diffusion flow switch NPN / PNP

Product Description

FGS heat guide flow switch monitors the liquid flow of the pipeline in real time, provides switch output, 6 LED display the fluid status in real time, and can realize the following monitoring functions: medium reduction / increase of flow rate; medium presence / absence; medium flow / rest.It is suitable for the monitoring of fluid flow rate and flow break in the pipeline to prevent pump idling.It is widely used in petrochemical industry, electric power, gold treatment, steel mills, paper making, food products processing, water treatment, battery plant and other industries



Operating principle of FGS flow switch:



The FGS heat guide flow switch is designed based on the principle of heat exchange.

The heating module and heating sensing module are built in the probe. The heat conduction of the flow switch is closely related to the flow speed of the medium,

When measuring, the heat module emits from the heat guide flow switch. If there is no medium flow in the pipeline, the heat received by the heat sensor module is a fixed value; when the medium flows, the heat received by the heat sensor module will change with the flow rate of the medium. The heat sensor module transforms the temperature difference signal into an electrical signal, and then converts it into the corresponding standard analog quantity signal or contact signal output through the processor, which displays and controls the flow rate of the medium through this signal.



Its characteristics:



1. The probe anti-scale coating can effectively prevent the attachment of dirt and rust dirt in the pipe pipeline, and has stronger anti-pollution ability.

2. The full waterproof shell is designed for a wide pipe diameter, the high pressure type of any adjustment set point, and the pressure resistance of up to *0MPa indicator directly shows the flow change.

3. Effectively prevent the winding objects.
