Technical field
This utility model relates to sensor technical field, refers in particular to a kind of temperature sensor.
Background technology
Temperature is the physical quantity characterizing the cold and hot degree of object, is a critically important and universal measurement parameter during industrial and agricultural production.The measurement of temperature and control are to ensureing that very important effect is played in product quality, raising production efficiency, the saving energy, production safety, the development of promotion national economy.Due to thermometric universality, the quantity of temperature sensor ranks first in various sensors, accounts for 50%.
Existing temperature sensor, its detection part has good contacting with measurand, reaches thermal balance by conduction or convection current, so that the indicating value of temperature sensor can directly represent the temperature of measurand, general measure precision is higher.In certain temperature-measuring range, temperature sensor also can Temperature Distribution within Measuring Object.But the object the least for movable body, Small object or thermal capacity then can produce bigger measurement error, and conventional temperature sensor has bimetallic thermometer, glass liquid thermometer, pressure-type thermometer, resistance thermometer, critesistor and thermocouple etc..They are widely used in the departments such as industry, agricultural, business.Along with cryogenic technique is in extensively application and the research of superconductor technology of the departments such as defence engineering, space technology, metallurgy, electronics, food, medicine and petrochemical industry, the cryogenic temperature sensor measuring 120K temperature below is developed, such as cold-gas temperature meter, vapour tension thermometer, acoustical thermometer, paramagnetic salt thermometer, quantum thermometer, Low Temperature Thermal resistance and low temperature thermocouple etc..Cryogenic thermometer requires that temperature-sensing element volume is little, accuracy is high, repdocutbility and good stability.Utilizing the carbon-containing glass thermal resistance of porous borosilicate glass carbusintering is exactly a kind of temperature-sensing element of cryogenic thermometer, can be used for measuring the temperature in the range of 1.6～300K.
Refrigerator is also required to use temperature sensor.The Chinese utility model patent of Patent No. " 201520531666.X " discloses a kind of refrigerator temperature sensor, including: critesistor, connection wire, the first epoxy resin layer, the second epoxy resin layer and cabinet；Described cabinet is the pipeline shape of one end open；Described critesistor by resistance welding with the described wire that is connected, forms the first epoxy resin layer described in encapsulating capitiform after weld coating epoxy resin cure, inserts in described cabinet inner chamber；Described connection wire one end is placed in the inner chamber of described cabinet, be filled with described second epoxy resin layer in the inner chamber of described cabinet to carry out solidification fixing with the described gap being connected wire, and the other end of described connection wire is drawn from the opening of described cabinet.Existing refrigerator temperature sensor main problem is that: properties of product are unstable, the response time is inaccurate, waterproof effect is poor.
Therefore, defect based on above-mentioned existing temperature sensor, need existing temperature sensor is improved.
Summary of the invention
The purpose of this utility model is to provide a kind of temperature sensor for the deficiencies in the prior art, and this sensor solves existing for existing temperature sensor: the defects such as properties of product are unstable, the response time is inaccurate, waterproof effect is poor.
For achieving the above object, this utility model is achieved through the following technical solutions:
Temperature sensor, including sensor critesistor, sensor critesistor is connected to connect terminal by wire rod, and sensor critesistor is wrapped with band glue heat-shrinkable T bush, scribbles moistureproof silica gel outside sensor critesistor.
Wire rod is arranged with locking plate with being connected terminal junction.
Sensor critesistor is placed in plastic housing, coats the first epoxy resin layer, the second epoxy resin layer between sensor critesistor and plastic housing.
Posting indicateing arm outside wire rod, indicateing arm can use electrical adhesive tape.
Connecting terminal connection and have multiple sensor critesistor, a plurality of wire rod is tied by electrician's glue.
The Standard resistance range of sensor critesistor is: R5 DEG C=5.06K Ω ± 2%, B5/25=3839K ± 2%.
The beneficial effects of the utility model are: at the outside wrap glue heat-shrinkable T bush of sensor, use locking plate connecting terminal, can increase the water proofing property of product, stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
See that Fig. 1, this utility model temperature sensor include: sensor critesistor 1, connection terminal 2, band glue heat-shrinkable T bush 3, indicateing arm 4, electrician's glue 5, locking plate 6.
This utility model includes sensor critesistor 1, sensor critesistor 1 is connected to connect terminal 2 by wire rod, connect terminal 2 and insert on the panel of refrigerator, sensor critesistor 1 is wrapped with band glue heat-shrinkable T bush 3, the water proofing property of sensor critesistor 1 can be strengthened with glue heat-shrinkable T bush 3, scribble moistureproof silica gel outside sensor critesistor 1, use this coating, the moisture resistance of sensor critesistor 1 can be greatly improved, so that the performance of sensor gets a promotion.
Further, sensor critesistor 1 is placed in plastic housing, coats the first epoxy resin layer, the second epoxy resin layer between sensor critesistor 1 and plastic housing.
Wire rod is arranged with locking plate 6 with being connected terminal 2 junction, wire rod can be played invigoration effect with the connection being connected terminal 2 by locking plate 6 one aspect, on the other hand fixation can also be played, certainly, some sensor critesistor 1 need not be put in the refrigerating chamber of refrigerator, it is possible to need not wrap glue heat-shrinkable T bush 3.
