The protection casing is by outer to interior including stainless steel layer, graphite alkene layer or graphite layer. The utility model discloses a disc protective housing to set up graphite alkene layer in the protective housing, it is more even to enable to conduct heat. The heat exchange of air within on the other hand epoxy polymeric material keeps apart thermistor and protects the casing to keep apart the thermal signal, independently obtained the non -interfering thermal signal respectively, can improve temperature sensor's precision greatly.
Description
Technical field
The utility model relates to field of temperature measurement in hot melt adhesive production run, relates to temperature sensor particularly.
Background technology
Hot melt adhesive is a kind of plastic bonding agent, and in certain temperature range, its physical state changes with temperature change, and chemical characteristic is constant, and it is nonpoisonous and tasteless, belongs to environmental-protecting chemical product.Because its product itself is solid, be convenient to packaging, transport, store, pollution-free, non-toxic; And production technology is simple, high added value, advantages such as bonding speed is large, speed is fast and enjoy favor.Hot melt adhesive needs its heating temperature of Accurate Determining in industrial process, and this is to appraising the quality of a product, and seeks best production technology and plays very important effect.
Because the applied environment of temperature sensor is complicated, various acid, alkali, heat, electricity, luminous environment all can affect the measuring accuracy of temperature sensor.Thermally sensitive temperature sensor utilizes metal along with temperature variation, and the feature that its resistance value also changes carries out measuring tempeature.For different metal, temperature was once often changing, and resistance change is different, and resistance value can directly as output signal.In order to realize the rapid detection of temperature, traditional method adopts Heat Conduction Material to be encapsulated in conical containment vessel by thermistor, but the uniform heat conduction of thermistor and measuring accuracy cannot promote further.
Utility model content
The utility model provide a kind of can uniform heat conduction improve the temperature sensor of measuring accuracy, described temperature sensor comprises protective housing, the several thermistors be arranged in protective housing.Heat conduction adhesives is coated and be bonded and fixed in protective housing by thermistor, and several thermistor is kept apart by polymerization of epoxy resins material.It is characterized in that, described temperature sensor protecting housing is collar plate shape, and protective housing comprises stainless steel layer, graphene layer or graphite linings from outside to inside.
Described heat conduction adhesives encapsulation thermistor is also adhered in protective housing.
Described thermistor is posistor or negative tempperature coefficient thermistor.
Described temperature sensor also comprises wire, and for exporting the current signal of several thermistor, described wire is coated and be fixed on inside protective housing by heat-conducting insulation material.
Described heat-conducting insulation material is heat-conducting silicone grease.
Described heat conduction adhesives is heat-conducting silicone grease or the tackifier through conductive filler.
Utility model people of the present utility model breaches original technical thought, changes the conical containment vessel of temperature sensor into disc, is conducive to uniform heat conduction.By specific structure, the graphene layer in containment vessel contributes to uniform heat conduction, and stainless steel layer contributes to the corrosion resistance improving temperature sensor.Several thermistor isolated by polymerization of epoxy resins material; thermal signal is isolated; independently obtain non-interfering thermal signal; avoid the heat signal impact being subject to single direction or position; stop to carry out heat interchange between gas in protective housing and thermistor simultaneously, improve measuring accuracy.Although the aisle spare being conveyed into thermistor of thermal signal diminishes; but greatly can improve the precision of temperature sensor; simultaneously by the heat conduction transmission of wire, the uniformly transfer heat of containment vessel takes into account among the design of temperature sensor, improves sensitivity and the degree of accuracy of temperature sensor.
