Description
Technical Field
The utility model relates to a resistance rule technical field, concretely relates to NTC resistance rule.
Background
The resistance gauge refers to a sensor for measuring a degree of vacuum. The traditional resistance gauge adopts tungsten wires as resistors, has short application time under the conditions of high humidity or serious pollution, usually can be damaged within 1-2 weeks, and has short service life.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that current resistance gauge adopts the tungsten filament as resistance, and the time of application is not long under the occasion that humidity is big or pollute more seriously, and life is shorter, therefore, the utility model provides a NTC resistance gauge, through adopting NTC thermistor to with the pin nickel plating of octagonal seat, seal the structural encapsulation through the glass, with the life of extension resistance gauge in the occasion that humidity is great or pollute seriously.
The utility model discloses a following technical scheme realizes:
an NTC resistance gauge comprises a tube body, an octagonal seat and an NTC thermistor, wherein the NTC thermistor is connected to a resistance gauge wire pin of the octagonal seat; the octagonal seat is fixedly arranged on the pipe body.
Furthermore, the NTC thermistor is connected to a pin of a resistance gauge wire of the octagonal seat in a welding mode.
Further, the inner edge of the bottom of the octagonal seat is hermetically installed with the top of the pipe body through an encapsulant.
Further, the encapsulant adopts epoxy resin glue.
Further, the model of the NTC thermistor is B57540G 1502.
Further, the length direction of body is provided with a shielding section of thick bamboo, and the diameter size of a shielding section of thick bamboo is 5.5 mm.
Further, the NTC resistance gauge is packaged by adopting a glass sealing structure.
The utility model provides a pair of NTC resistance gauge replaces the tungsten filament as resistance through NTC thermistor to connect on the resistance gauge wiring pin of octagonal seat, then with octagonal seat fixed mounting on the body, seal the structure encapsulation through the glass at last, with the corrosion resistance that improves the resistance, thereby prolong the life of resistance gauge in the great or serious occasion of pollution of humidity.

The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an NTC resistance gauge includes a tube, an octagonal seat and an NTC thermistor c connected to a resistance gauge wire pin of the octagonal seat by welding. Generally, the pins of the resistance gauge wire of the octagonal seat are a second pin 2 and a third pin 3, one end of the NTC thermistor is connected to the second pin 2 of the octagonal seat in a welding manner, and the other end of the NTC thermistor is connected to the third pin 3 of the octagonal seat in a welding manner; and coating an encapsulant on the inner edge b of the bottom of the octagonal seat to be hermetically mounted with the tube body. The encapsulant of this embodiment adopts epoxy glue to realize the fixed of octagon seat and body, and reach insulating purpose.
Wherein, eight regions of eight octagonal seats are respectively provided with a pin, specifically a circle a of each region in fig. 1.
In this embodiment, a shielding cylinder B is arranged in the length direction of the pipe body A; the diameter size of the shielding cylinder B is 5.5 mm.
Further, the NTC thermistor is model B57540G1502 by TDK corporation. And plating nickel on the pins of the octagonal seat. The size of the tube body is as follows.
Further, the NTC resistance gauge is packaged by adopting a glass sealing structure.
Specifically, the NTC thermistor is fixedly arranged on a pin of the octagonal seat, the octagonal seat is fixedly arranged on the tube body, and finally the tube body is packaged through the glass sealing structure, so that the service life of the resistance gauge on occasions with high humidity or serious pollution is prolonged. In addition, the service life of the resistance gauge in the occasion with high humidity or serious pollution is prolonged by plating the pins of the octagonal seat with nickel.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
