Abstract
The utility model relates to a novel platinum resistance thermometer used for measuring surface temperature. The utility model is provided with a temperature sensing element of a thick-film resistor, a thin-film resistor or an inner winding type small-sized ceramic platinum resistor element, and the temperature sensing element is arranged in a flat casing which is made of heatproof polymer material, metal or alloy. The flat casing is filled with heatproof oxide or heatproof resin insulative material, and is welded onto a down-lead of the platinum resistor element by using a three-core or four-core polytetrafluoroethylene insulated conducting wire as an extension wire. The flat casing is entirely encapsulated. The utility model can be widely applied to surface temperature measurement for various mechanical parts, and the utility model is especially suitable for the temperature measurement of coils of stators and rotors in generators.
Description
The utility model relates to a kind of surface temperature measurement platinum-resistance thermometer, and it can be used to the surface of metal, non-metallic component and pipeline in the machinery and carries out temperature survey accurately and reliably, the thermometric of applicable especially generator unit stator and rotor winding.
As everyone knows, garden column resistance temperature-sensing element is not suitable for surface temperature measurement, at it inconvenience is installed, shortcoming such as anti-vibration and thermal response difference not, developed a kind of plane platinum-resistance thermometer of mica frame, it is that platinum filament is wrapped on the mica frame, clamping mica frame with stainless steel substrates again makes, this version, the unrelieved stress that makes platinum filament be produced when coiling can not get eliminating fully, and when under extraneous pressure condition, using, the winding platinum filament can directly be subjected to external force, these factors can make the resistance value of element change, thereby have reduced the temperature measurement accuracy and stability of element, in addition, the also easily contaminated in use and damage of mica platinum resistance, serviceable life is not long, and thermal response is unhappy, can not satisfy thermometric requirement accurately and reliably.
The purpose of this utility model is the shortcoming that overcomes the plane platinum-resistance thermometer of mica frame, adopt membrane type platinum resistance element or interior around the small-sized ceramic platinum resistance element of formula as temperature-sensing element, and in the flat valve jacket with its overall package of packing into, substitute original mica platinum-resistance thermometer with this novel platinum-resistance thermometer.
The technical solution of the utility model be with thick film, sheet resistance or interior around the small-sized ceramic platinum resistance element of formula as temperature-sensing element, and it is packed in the flat valve jacket that heat-proof macromolecule material, metal or alloy make, the filling compacting has refractory oxides or heat-resisting lipid insulating material in the valve jacket, the temperature-sensing element lead-in wire is gone up with extending out from valve jacket after the wire bonds, and valve jacket is packaged into an integral body, promptly make the surface temperature measurement platinum-resistance thermometer.
This practical embodiment is illustrated in conjunction with the accompanying drawings.
Fig. 1 is a heat-proof macromolecule material type surface temperature measurement platinum-resistance thermometer structural drawing,
Fig. 2 is metal mold surface temperature measurement platinum-resistance thermometer structural drawing.
Embodiment 1:
As shown in Figure 1,1. temperature-sensing element, 2. substrate, 3. brace, 4. mounting hole, 5. stuff, 6. lead, 7. valve jacket.This is a kind of heat-proof macromolecule material surface resistance thermometer, with thick-film platinum resistance, film platinum resistor or interior temperature-sensing element 1 around the small-sized ceramic platinum resistance element of formula.Be encased in the flat valve jacket of making by heat-proof macromolecule material 7, filling compacting refractory oxides or heat stable resin class insulating material 5 in the shell, the lead 6 welding backs of silver, nickel, copper or their alloy wires that insulate with three cores or the poly-tetrafluoro of four-core on the lead-in wire of platinum resistance element extend out from valve jacket 7, valve jacket is packaged into an integral body, stick on certain size again, on the substrate 2 of definite shape (substrate available metal sheet), promptly become the platinum-resistance thermometer that a surface temperature measurement is used, operating temperature range is-50~+ 150 ℃.
Embodiment 2:
This be a kind of metal mold surface resistance thermometer and the foregoing description main difference be that valve jacket 7 is flat valve jackets of being made by metal or alloy, operating temperature range is-200~+ 650 ℃.
The utility model shows with on probation after tested, when under 2 tons of following static pressures, using, the application performance of temperature-sensing element is unaffected, its technical indicator meets our professional standard ZBYBO1-85 and international standard IEC751, the calibration of thermometer number is Pt100 and Pt1000, and built-in element is that unit piece or dual-element all can. Characteristics of the present utility model are: can hold high pressure, volume thin little, reliable and stable, reflection is very fast, vibration strength is good, not contaminated, long service life, easy to use, the forms such as available screw installation and bonding fixed installation, be fixed on the surface of testee, also can be embedded in the silicon steel film trap of mechanical part such as generator unit stator, or press solidly between the unit under test object, can be widely used in each mechanical part surface temperature measurement, be specially adapted to the thermometric of generator unit stator and rotor coil.
