Abstract
The utility model relates to a screw type temperature sensor, comprising a temperature sensitive nut, a thermistor mounted in the temperature sensitive nut, and a wire connected with the thermistor, wherein the temperature sensitive nut is hexagon, one end of the temperature sensitive nut is provided with a mounting head, inside the temperature sensitive nut there is provided a temperature sensitive cavity, one of the temperature sensitive cavity, far from the mounting head is communicated with external environment, the other end of the temperature sensitive cavity extends into the mounting head, and the thermistor is mounted in the temperature sensitive cavity in the mounting head. The screw type temperature sensor is simple in mounting and easy in dismounting and replacing, is closer to a heat source, is rapid in temperature sensitive speed and accurate in temperature measurement; the heat conductive silica filled in the temperature sensitive cavity rapidly transmits the sensed heat to the thermistor, thereby further increasing the temperature sensing speed of the sensor; and a fixed rubber sleeve mounted at the root portion of the cylindrical mounting head of the temperature sensitive nut can ensure the sealing performance of the temperature sensitive end of the temperature sensitive nut, can ensure the accuracy of temperature detection, and enables the temperature sensitive nut to be firmly fixed.
Description
Technical field
The utility model relates to a kind of sensor, specifically, is a kind of screw-type temperature sensor.
Background technology
Temperature sensor is that a kind of being used for is converted into the components and parts that resistance is exported signal with temperature signal, is applied to nearly all field that needs the control temperature at present.
Present existing temperature sensor; Volume is bigger, can't be deep in equipment or the environment in the temperature zone to use, and traditional installing and fixing method is to be fixed on the temperature-sensitive head on the testee with the screw ring set; Cover the fluid sealant fixing seal then; The operation trouble needs amount of parts many, and cost is high.
The utility model content
The utility model can't deeply be installed to the original temperature sensor, and the installation procedure trouble, needs part many, and the shortcoming that cost is high has designed a kind of screw-type temperature sensor.
The utility model screw-type temperature sensor comprises the temperature-sensitive nut, is installed in the thermistor in the temperature-sensitive nut; The lead that links to each other with thermistor, described temperature-sensitive nut outer wall is a sexangle, temperature-sensitive nut one end is provided with installation head; Be provided with the temperature-sensitive cavity in the temperature-sensitive nut; The temperature-sensitive cavity communicates with the external world away from an end of installation head, and the temperature-sensitive cavity other end extends in the installation head, and thermistor is installed in the temperature-sensitive cavity in the installation head.
Preferably, described installation head is a column, and the installation head surface is provided with screw thread.
Preferably, described thermistor is connected with wire bonds.
Preferably, described installation head root also is equipped with fixedly gum cover.
Preferably, be filled with heat conductive silica gel in the described temperature-sensitive cavity, the temperature-sensitive cavity is coated with epoxy resin with an extraneous end that communicates.
The utility model screw-type temperature sensor; The temperature-sensitive nut is provided with installation head, and installation head is provided with screw thread, and installation head can screw in the threaded hole that testee is used for detecting; Because the outer wall of temperature-sensitive nut is a sexangle; Spanner directly turn temperature-sensitive nut is fixed on sensor on the testee, installs simply, and dismounting and change is easy.The installation head of temperature-sensitive nut is goed deep into testee, and more near thermal source, temperature-sensitive speed is fast, and it is accurate to measure temperature.The heat conductive silica gel that charges in the temperature-sensitive cavity is passed to thermistor fast with the heat of experiencing, and has further improved the temperature-sensitive speed of sensor.The fixedly gum cover of installing on the installation head root of temperature-sensitive nut column has guaranteed temperature-sensitive nut temperature-sensitive one end sealing, has guaranteed the accuracy of detected temperatures, and has made the temperature-sensitive fixed by nut firm.
Description of drawings
