Abstract
The utility model discloses a monolithic sintered internal wound spring-type platinum thermal resistor, which comprises a ceramic core. Wound spring-type platinum wires thread through the holes of the ceramic core; filling materials are arranged around the platinum wires; both ends of the ceramic core are provided with glazed end seals. Two outlet lead wires come from the platinum wires from the glazed end seals. The monolithic sintered internal wound spring-type platinum thermal resistor is characterized in that the filling materials are quartz sand sintered bodies formed in the way that after quartz sand is filled, the monolithic platinum thermal resistor is sintered. The performance of the monolithic sintered internal wound spring-type platinum thermal resistor is stable; and the service life is dozens of times longer than the service life of the prior internal wound-type platinum resistor. The monolithic sintered internal wound spring-type platinum thermal resistor can measure the temperature ranging from 200 DEG C below zero to 800 DEG C.
Description
Technical field
The utility model belongs to a kind of temperature sensor, specifically is a kind of integral sintered interior wrap spring type platinum resistance thermometer sensor.
Background technology
Traditional interior wrap spring type platinum resistance thermometer sensor,, include diplopore or four hole ceramic cores, be installed with the wrap spring type platinum wire in the hole of ceramic core, around the platinum wire is inserts, and there is glaze end-blocking head at the ceramic core two ends, and platinum wire is drawn two from glaze end-blocking head and drawn lead, inserts generally adopts high temperature insulating material such as aluminium oxide or silica flour, to guarantee platinum filament spring inertia in ceramic hole, play fixedly platinum filament effect, thereby make it in the medium-term and long-term work of high low temperature.But in producing the assembling use vibration is arranged unavoidably, the strong vibration meeting causes resistive platinum wire short circuit and disconnection, thus accurate thermometric just.
The utility model content
The utility model can be loosening in the strong vibration environment at powder filler, a kind of integral sintered interior wrap spring type platinum resistance thermometer sensor, is provided, inserts is replaced with a kind of integral sintered mixing new material, make inserts become as a whole with platinum resistance thermometer sensor, silk, ceramic core, and Vacuum Package forms, thereby makes the platinum resistance can be high temperature resistant, and low temperature is corrosion-resistant, antivibration, anti-high-intensity magnetic field, anti-heavy current.
The technical solution of the utility model is as follows:
Wrap spring type platinum resistance thermometer sensor, in integral sintered, include diplopore or four hole ceramic cores, the wrap spring type platinum wire penetrates in the ceramic core hole, around the platinum wire is inserts, there is glaze end-blocking head at the ceramic core two ends, platinum wire is drawn two from glaze end-blocking head and is drawn lead, it is characterized in that described inserts for after mixing silica sand and filling through high temperature with the integral sintered solid that forms of platinum resistance thermometer sensor.
The utility model adopts silica sand as inserts, to mix silica sand inserts and platinum resistance thermometer sensor, silk, the ceramic core sintering of heating then, make it into as a whole, thereby around the shortcoming of formula platinum resistance, reach tens times than interior around the formula platinum resistance around the formula spring formula platinum resistance stable performance life-span in integral sintered in having changed.Energy measurement-200～800 ℃ can be used for the armoured thermal resistance of all size.
