Abstract
The calorimetric sensor for determining foamed medium state is characterized by that it contains thermocouple coaxially suspended in ceramic tube, resistance wire winded round outer wall of the above-mentioned ceramic tube and conducting wire connected with it for heating it, ceramic insulating encapsulation body for radially encapsulating the resistance wire from interior to exterior in turn and metal enclosure, insualting material for covering thermocouple from interior to exterior in turn along the radial direction at end of resistance wire and its enclosure and armoured cable connected with metal enclosure. It also is a differential sensor formed from two above-mentioned calorimetric sensors whose tail ends are fixed and connected together. It can be used in several industrial fields of foam floatation, beer production, fire-fighting, paper-making and radioactive waste water concentration and detergent production etc.
Description
Technical field
A kind of calorimetric sensor of judging that the foam medium state is used belongs to calorimetric sensor manufacturing technology and foam medium state measurement field.
Background technology
At present, detection also judges that the method for foam medium state has following several: (1) radiation detection method: it will install radiation source in industry spot, may injure operating personnel, but also has the induced radiation problem of equipment, sensor places the outside of measured medium simultaneously, can influence measurement effect.For the less solution of density, because solution is low for radiation decrement, transducer sensitivity reduces, and usable range is restricted.(2) dielectric conductance mensuration: the terminal of its conductivity sensor is tiny conducting probe, when in high viscosity solution, using, and can be very fast because the detecting probe surface fouling makes sensor failure.(3) medium conduction state mensuration:, thereby can not be used in the inflammable and explosive solution because this method will be at medium conducted inside electric current.
Summary of the invention
The calorimetric sensor of the object of the present invention is to provide that a kind of adaptability is strong, highly sensitive, the judgement foam medium state of good reliability and long service life being used.
The invention is characterized in that it contains: the outstanding coaxially thermopair that is loaded in the ceramic pipe, the heating lead that is wrapped in the resistance wire of above-mentioned ceramic pipe outer wall and is attached thereto, radially live the ceramic insulation packaging body and the metal casing of resistance wire successively by lining and outer package, radially encase the insulating material and the involucrum thereof of thermopair successively by lining and other places in the resistance wire end, the four-core sheathed cable that links to each other with metal casing, it also is a kind ofly to be fixedly connected at the differential type that above-mentioned calorimetric sensor together forms by two at tail end and to judge the sensor that the foam medium state is used.
Use proof: it has reached intended purposes.
