Abstract
The utility model relates to a thermometer with double power supply modes. The thermometer includes a display unit casing, a thermometer body and a temperature measuring tube, wherein temperature sensitive elements of first and second onsite thermometers are mounted at the bottom of the temperature measuring tube, the first onsite thermometer is a bimetallic thermometer, the second onsite thermometer is a thermocouple thermometer, and each of the first and second onsite thermometers includes an independent display unit and power supply mode. According to the utility model, the thermometers in two different measuring manners are combined, each thermometer includes the independent display unit for value display, and a storage battery and a solar battery respectively supply power for the two thermometers, so that measurement can be still implemented under the condition that the storage battery is powered off. The thermometer with double power supply modes is compact in structure, convenient to install, lower in the cost and safe in use, and can be widely applied to industries including petroleum, chemistry, steel, printing and dyeing and pharmacy.
Description
Technical field
The present invention relates to a kind of scene temperature measurement mechanism, especially a kind of thermometer.
Background technology
Existing scene temperature meter only has a kind of Presentation Function, a kind of metering system and a kind of power supply mode conventionally, and when a kind of display mode fault, a kind of power supply mode fault or a kind of metering system fault, it is just completely ineffective.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of duplicate supply mode thermometer is provided, have two metering systems, and have separately independently power supply mode, the more accurately metering system of safety is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of duplicate supply mode thermometer, there is display unit shell, body and temperature tube, and the temperature-sensing element of primary scene thermometer and secondary scene thermometer is installed in temperature tube bottom; Described primary scene thermometer adopts bimetallic system cell, the temperature-sensing element of bimetallic system cell is bimetallic strip, bimetallic strip is arranged on temperature tube bottom, connect the first testing circuit and carry out temperature detection, testing result is sent to the first Graphics Processing module, the first Graphics Processing module connects the first display unit, and battery module is the thermometer power supply of described primary scene; Described secondary scene thermometer adopts thermocouple thermometer, the temperature-sensing element of thermocouple thermometer is thermopair, the installation of TC is in temperature tube bottom, connect the second testing circuit and carry out temperature detection, testing result is sent to the second Graphics Processing module, the second Graphics Processing module connects the second display unit, and solar module is the thermometer power supply of the described secondary scene; The first display unit and the second display unit are positioned at display unit shell.Described solar module comprises the external tabula rasa that is subject to.
The bimetallic strip of bimetallic system cell and the installation of TC are in same temperature tube bottom, and therefore, when user installation is used, measuring channel only need be offered a thermometer hole.
The invention has the beneficial effects as follows: the present invention combines the thermometer of two kinds of metering systems, adopt respectively corresponding independent display unit to carry out numerical value demonstration, adopt independently power supply mode to power simultaneously, guaranteed not have electric in the situation that and still can measure at accumulator.Compact conformation of the present invention, easy for installation, cost is lower, uses safety, can be widely used in the industries such as oil, chemical industry, iron and steel, printing and dyeing, pharmacy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
Two displays temperature meters as shown in Figure 1, have display unit shell 1, body 2 and temperature tube 3, and the temperature-sensing element of primary scene thermometer and secondary scene thermometer is installed in temperature tube bottom; Described primary scene thermometer adopts bimetallic system cell, the temperature-sensing element of bimetallic system cell is bimetallic strip 4, bimetallic strip is arranged on temperature tube bottom, connect the first testing circuit 5 and carry out temperature detection, testing result is sent to the first Graphics Processing module 6, the first Graphics Processing module connects the first display unit 7, and battery module 8 is the thermometer power supply of described primary scene; Described secondary scene thermometer adopts thermocouple thermometer, the temperature-sensing element of thermocouple thermometer is thermopair 9, the installation of TC is in temperature tube bottom, connect the second testing circuit 10 and carry out temperature detection, testing result is sent to the second Graphics Processing module 11, the second Graphics Processing module connects the second display unit 12, and solar module 13 is the thermometer power supply of the described secondary scene.The first display unit and the second display unit are positioned at display unit shell.Described solar module comprises the external tabula rasa 14 that is subject to.
Bimetallic strip and the installation of TC are in same temperature tube 3 bottoms, and therefore, when user installation is used, measuring channel only need be offered a thermometer hole.The present invention designs succinctly, diverse in function, use safety, accuracy of reading, and easy for installation, and installation cost reduces.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on instructions, must determine its technical scope according to claim scope.
