Abstract
The utility model relates to a solar-energy-powered thermometer with double display modes. The thermometer comprises a display unit housing, a thermometer body, a temperature-measuring pipe, a power voltage detecting unit, and a solar-energy storage battery. The temperature-sensing element of a first field thermometer and the temperature-sensing element of a second field thermometer are both installed at the bottom of the temperature-measuring pipe. The first field thermometer and the second field thermometer have independent display units. When the power voltage is determined to be lower than preset voltage, the thermometer is powered by the solar-energy storage battery. The solar-energy-powered thermometer with double display modes has characteristics of compact structure, easy installation, low cost, and safe use, and can be widely used in industries such as petroleum, chemical industry, steel, printing and dyeing, and pharmacy or the like.
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 and a kind of metering system conventionally, and power supply mode is single, and when a kind of display mode fault, a kind of metering system fault or power-off, 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 pair of display mode thermometer is provided, and have two metering systems, can rely on sun power and battery to maintain continued power, the more accurately permanent effectively metering system of safety is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pair of solar powered thermometer of display mode, have display unit shell, body and temperature tube, 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 the first power 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 second source 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; Also comprise supply voltage detecting unit, it connects respectively the first power module and second source module and solar storage battery, supply voltage detecting unit has voltage comparison unit and change-over switch, when the first power module and/or second source module voltage being detected lower than predeterminated voltage, by change-over switch, cut off the first power module and/or second source module and replace the first power module and/or second source module is that above-mentioned primary scene thermometer and/or secondary scene thermometer are powered with solar storage battery.
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, when undertension, adopt solar storage battery power supply simultaneously.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, it is the thermometer power supply of described primary scene that the first Graphics Processing module connects the first display unit 7, the first power modules 8; 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 second source 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.Also comprise supply voltage detecting unit 14, it connects respectively the first power module and second source module and solar storage battery 15, supply voltage detecting unit 14 has voltage comparison unit 16 and change-over switch 17, when the first power module and/or second source module voltage being detected lower than predeterminated voltage, by change-over switch, cut off the first power module and/or second source module and replace the first power module and/or second source module is that above-mentioned primary scene thermometer and/or secondary scene thermometer are powered with solar storage battery.Solar storage battery 15 also comprises and is subject to tabula rasa 18.
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 service time is long, 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.
