Background technology
At present, the usual way of accelerating wear-resisting temperature sensor thermal response time has two kinds, and first kind for utilizing the fast characteristics of thermocouple temperature sensitive element hot junction temperature-sensitive, the thermal response time of quickening thermometric; Second kind for being made into the welding two-section type with the protection tube of wear-resisting temperature sensor; a joint wear-resistant protection pipe that is about to be equipped with temperature-sensing element saves the common stainless steel protection tube with another and is welded and fused, with this increase the scuff resistance of protection tube and the heat radiation that reduces to bring because of the wear-resistant protection thickness of pipe to the influence of temperature sensor thermal response time.Though both can both reach the effect of accelerating thermal response time, but, though first kind of mode thermal response time is very fast, its temperature measurement accuracy, particularly the temperature measurement accuracy of low-temperature zone is far below the platinum resistance thermometer sensor, temperature-sensing element, so be not used in this kind of low-temperature zone scheme usually.Though second method has strengthened the anti-wear performance of temperature sensor wear-resistant protection pipe; but it is to be cost with the thermal response time of sacrificing temperature sensor; the thermal response time of temperature sensor reduces not obvious; and because temperature-sensing element that adopts and wear-resistant protection pipe and structure do not have breakthrough change, so effect is not remarkable.
In rubber for tire sulfuration thermometric existing platinum resistance sensor thermal response time lag behind, wear-resistant and corrosion resistance is barely satisfactory, serviceable life is short.
The utility model content
The purpose of this utility model is: for guaranteeing the temperature control in the rubber for tire sulfuration production run, accelerate the thermal response time of temperature sensor and the thermometric accuracy that improves wear-resisting, corrosion-resistant and temperature sensor significantly, a kind of quick temperature measurement wear-resisting type platinum resistance thermometer sensor, is provided.
For achieving the above object; the technical scheme that is adopted is: a kind of quick temperature measurement wear-resisting type platinum resistance thermometer sensor; comprise wear-resistant protection pipe and the micro platinum thermal resistance that places described protection tube; it is characterized in that: in the described protection tube; the temperature-sensitive end is equipped with quick conductive that is connected with described platinum resistance thermometer sensor; described micro platinum thermal resistance and described protection tube inwall closely cooperate, and to therebetween minimum gap filling Heat Conduction Material.
Consider Si Taili (stellite) alloy wear-resisting, corrosion resistance and good, described protection tube selects for use stellite to make.
Described quick conductive is that the employing temperature conductivity is the highly heat-conductive material of 429W/mk, as silver powder.
Described platinum resistance thermometer sensor, is the only high-precision micro platinum resistance thermometer sensor, of 0.8mm of element diameter.
Described Heat Conduction Material is the silicone material, preferably adopts Thomas's high temperature heat-conducting glue.
The beneficial effects of the utility model are: be equipped with the high-precision micro platinum resistance thermometer sensor, that temperature element is of a size of conventional platinum resistance thermometer sensor, 1/2; make between micro platinum thermal resistance and the protection tube and closely cooperate; and the gap is filled with Heat Conduction Material; particularly in order to accelerate the thermal response time of wear-resisting platinum resistance thermometer sensor; increase quick conductive at protection tube temperature-sensitive end (hot junction), thermal conductivity improves 8 times.By selection to the protection tube material; the more conventional wear-resistant protection pipe of wear-resisting, decay resistance improves in more than three times; thermal response time was less than 5 seconds; be 1/3 of the wear-resisting platinum resistance thermometer sensor, product of routine; thereby; both satisfy corrosion-resistant in the rubber for tire sulfidation, abrasion resistance properties requirement, improved temperature sensor quick temperature measurement, the accurate effect of thermometric again.
The utility model compact conformation, convenient and practical, effect is obvious.
