- Q:What is a thermal conduction flow switch?
- The thermal conductivity flow switch is also called thermal conductivity type electronic flow switch.
Now use the FR series of electronic thermal conductivity flow switch to illustrate the thermal guide flow switch to explain the working principle:
The FR series thermal conductivity switch is made up of two temperature sensors, power supplies, signal processors and output relays or NPN / PNP transistor outputs.
The temperature sensor for this type of thermal conductivity flow switch is manufactured using special semiconductors.
The physical characteristics of these two sensors are very close, and separated by a certain distance, mutual heat can be ignored.
The sensor paired the temperature of the tracking media. The voltage drop of these sensors is proportional to the temperature and is accurate over a wide temperature range. One of the sensors (Sensor1) is heated to be higher than the medium temperature.
Another sensor (Sensor2) is the same as the medium temperature we have for the reference sensor.
The same constant current flows through the two sensors to produce a voltage difference that is inversely proportional to the amount of heat that Sensor1 takes away by the media.
As the medium flow rate and take away the heat is proportional to, so by measuring the voltage difference between the two sensors, we can see the flow rate of the media at this time, so as to know through the flow of media.
As shown in the picture ~!
- Q:Wiring Principle and Diagram of Target Flow Switch
- And the user does not need to install and wiring the site, also to avoid the installation of the target water flow switch is not accurate lead to the unit
- Q:The flow switch is used in air conditioning
- Flow switch can be a good solution and maintenance of this problem, the German Kewell plunger flow switch FP53 series of the principle of structure: on-line installation, mechanical flow switch for liquid or gas media. Sturdy plastic, aluminum or stainless steel housing optional. The medium pushes the plunger spring to the set position to exert a passive on-off signal by the magnetic field acting on the reed switch.
- Q:Huawei glory 5s set the flow switch where
- Switch traffic somewhere in the phone settings:
Open the settings, you can see the top of the data network (flow switch)
Click on the cellular data switch, and then the top of the switch fluctuations to the left, you can, if the fluctuations to the right, is to open.
- Q:Apple phone on how to switch the Bluetooth switch switch
- There is also a reason, that is, Europe and the United States infinite flow package is quite popular
If you really need to change, you can install the plug-in to add traffic shortcut switch.
- Q:My phone always automatically open the data flow switch, sometimes attached to wifi also so.
- If it is abnormal switching and non-misuse of the case can only repair the test
- Q:Water flow switch wiring need to pay attention to what
- The When wiring, the power should be switched off
The In addition to the micro-switch terminals, grounding screws other than the other screws can not touch, micro-switch wiring can not be too much force, or may be broken
- Q:Do you want to set the flow switch for the self - sprayed outlet of the high fire water tank?
- or alarm valve pressure switch and other switching signals should be able to automatically start the fire pump.
- Q:General fire tank with what style flow switch
- National standard GB 50974-2014 "fire water supply and fire hydrant system technical specifications" 11.0.4 provides: fire pump should be pump water pipe on the set of pressure switch, high fire water tank outlet pipe on the flow switch, or alarm valve pressure switch Signal directly to start the fire pump. Fire water pump room pressure switch should be introduced into the control cabinet. That is, the fire tank installed on the outlet pipe flow switch, is the statutory mandatory requirements.
- Q:Millet note2 how to use the software flow switch to open?
- Second, and then in its page to find the [flow] button icon, click on the choice of [network control] column
