Abstract
The utility model discloses a thermometer bulb structure which comprises a temperature bulb (1) and an inner tube (3). A temperature sensor (2) is installed in the inner tube (3). According to the utility model, the temperature sensor is disposed at the bottom of the inner tube inside the temperature bulb. That is to say, the temperature sensor is placed in the middle position of the temperature bulb in a vertical thermal field. Thus, measuring difference caused by different placement depths of the temperature bulb and the temperature sensor is eliminated.
Description
Technical field
The utility model relates to a kind of thermometer temperature sensing parts.
Background technology
In order to carry out remote monitoring, current temperature controller is generally equipped with two groups of independently temperature measuring equipments simultaneously: the temperature measuring equipment (thermometer bulb) of scene temperature indication and temperature measuring equipment (temperature sensor) for remote monitoring.
In traditional structure, the position of temperature sensor occupy top or the below of thermometer bulb, because the temperature field of dut temperature is subject to the impact of environment temperature to have a vertical temperature band, temperature sensor and thermometer bulb are due to the difference of upright position of living in, between temperature sensor and thermometer bulb, there is the temperature difference, cause both measurement data variant.
Summary of the invention
The technical problems to be solved in the utility model: two groups of problems that independently temperature measuring equipment measurement temperature there are differences for present temperature controller, provide a kind of thermometer bulb structure that can overcome temperature contrast.
Technical solutions of the utility model:
A thermometer thermometer bulb structure, comprises thermometer bulb and inner tube, it is characterized in that: mounting temperature sensor in inner tube.
Temperature sensor is platinum resistance.
Temperature sensor is arranged on the bottom of inner tube.
The utility model beneficial effect:
Temperature sensor is held in place to inner tube in thermometer bulb bottom, i.e. temperature sensor centre position in thermometer bulb in vertical temperature, thus eliminate thermometer bulb and the degree of depth different measurement difference that causes of temperature sensor temperature sensitive resister because of set-point.
accompanying drawing explanation:
Fig. 1 is the schematic diagram of traditional structure.
Fig. 2 is the structural representation of the utility model embodiment 1.
embodiment:
Embodiment 1: in thermometer bulb 1, be filled with temperature sensing medium, middle part is provided with inner tube 3, and temperature sensor 2 is arranged in inner tube 3, is positioned at the bottom of inner tube 3; 4 one of resistance leads are connected with temperature sensor 2, and draw from the head of inner tube 3 other end.Temperature sensor 2 can be the simple metal such as platinum, Jin Huotong, also can adopt rhodium iron or phosphor bronze alloy; Because platinum resistance is the most accurate, so in the present embodiment, temperature sensitive resister 2 is platinum resistance.
Claims (3)
1. a thermometer thermometer bulb structure, comprises thermometer bulb (1) and inner tube (3), it is characterized in that: the interior mounting temperature sensor of inner tube (3) (2).
2. thermometer thermometer bulb structure according to claim 1, is characterized in that: temperature sensor (2) is platinum resistance.
3. thermometer thermometer bulb structure according to claim 1, is characterized in that: temperature sensor (2) is arranged on the bottom of inner tube (3).
