Insulation type magnetic flap application scope and principle of the thermometer

magnetic flap thermometer is in the tank farm using common a kind of liquid level measuring instrument, in the process of actual use, the magnetic flap thermometer is a widely used in industrial production of liquid level measuring instrument, has been widely used in food, chemical, pharmaceutical and other industries. Insulation type magnetic flap thermometer is according to the requirements. Thanks to the fall in outdoor tanks will because winter temperatures part of vats of liquid icing, magnetic flap thermometer by the principle of communicating vessels, once tested inside the tank of liquid icing, cause the liquid to flow, so the magnetic flap the level measurement of the thermometer will not be able to undertake, so we need to the magnetic flap thermometer for thermal insulation of pipeline operation. Generally we often use the methods are divided into two kinds, one is electric heating/electric thermal insulation, another is a vacuum jacketed insulation, electric heating/electric heating is through the wire coil in the magnetic resistance thermometer supervisor on turning liquid heating pipe to make the pipe above freezing, ensure the liquid in the tank will not because temperature is too low and freezing, vacuum jacketed heat preservation principle, and we are of the same household heat preservation principle of the vacuum flask, main external vacuum to eliminate heat transfer and convection, so can reduce the outdoor temperature at night when certain heat preservation effect, the purpose of heat preservation is to prevent being detection of temperature in the tank is too low, make the detection of liquid ice and freezing. When vacuum jacketed magnetic flap thermometer over a period of time, after the use of vacuum value rise means, vacuum jacketed need new extraction vacuum, we this time in a vacuum jacketed valve is installed in a vacuum pump, vacuum pump of vacuum jacketed for vacuum operation, to ensure that the vacuum jacketed tightness, guarantee the tested liquid will not be frozen, because temperature is too low to ensure the accuracy of the liquid level monitoring.
