Abstract
The utility model provides an inductive probe. The inductive probe comprises a humidity sensor, a metal gas shield, a probe and a lead wire, wherein the metal gas shield is die-cast through metal and is cylinder-shaped, and the diameter of a cavity formed in the metal gas shield is matched with that of a fixed bracket. The metal gas shield in the inductive probe provided by the utility model can be placed in dust to be measured, and can enable water vapor in the dust to penetrate the clearance of the material of the metal gas shield per se to enter the fixed bracket due to the metallic property per se, then the humidity sensor can analyze the humidity data in the dust, and meanwhile, the metal gas shield can prevent the dust from penetrating through the clearance of the material of the metal gas shield per se to enter the fixed bracket. Therefore, the inductive probe can be used in mediums of dust class safely, and the effect of humidity measurement is good.
Description
Technical field
The utility model relates to a kind of inductive probe that is used for measuring the humidity of dust.
Background technology
Sensor usually is used for measuring indexs such as the temperature, humidity of testee more, and need directly touch measured medium.But self is made up of sensor electronic component, and for the medium of liquid type, dust class, sensor can not directly touch this type of medium, needs one and both can protect sensor, can touch the inductive probe of this type of medium again.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of easy to use, effective inductive probe of measurement humidity is provided.
For achieving the above object, the utility model adopts a kind of inductive probe, comprise humidity sensor, the metal gas guard shield, probe, lead, probe in a tubular form, the end of popping one's head in forms the wire insulation sheath, the other end extends to form fixed support, support bracket fastened diameter is less than the diameter of probe, radially offer one or more grooves on the support bracket fastened outer wall, form screw hole at support bracket fastened top, it is inner that wiring board is placed on probe, groove one side of the humidity sensor on the wiring board on fixed support, lead is arranged in the wire insulation sheath of probe, and lead is electrically connected with the wiring board formation; The metal gas guard shield is to use the die cast metal moulding, the metal gas guard shapes is a cylinder barrel shaped, the diameter and the support bracket fastened diameter of its inner cavity that forms are suitable, screw is formed on the top at the metal gas guard shield, the metal gas guard shield is set in fixed support one side of probe, and passes fixedlying connected of screw and screw hole formation metal gas guard shield and probe with screw.
The utility model provides novel inductive probe, metal gas guard shield in the inductive probe can be placed in the dust that will measure, the metal gas guard shield is because the characteristic of self metal, self material gap of steam permeable metal gas guard shield in the dust is entered in the fixed support, humidity sensor promptly analyzes the humidity data in the dust then, and simultaneously the metal gas guard shield can stop dust to enter self material gap again to enter in the fixed support.Therefore can be safely use, and it is effective to measure humidity at the medium of dust class.
In order to improve sealing, the utility model further is set between the inwall of the support bracket fastened top of probe and metal gas guard shield O-ring seal is set, and O-ring seal is set on the screw.
