Abstract
The utility model discloses the temperature measuring device of an electromechanical integration. The utility model is characterized in that a thermal resistance or a thermocouple is arranged on the capillary of the upper end of a thermometer bulb, and is covered with a metal cover; one end of the metal cover is connected with the thermometer bulb, and the other end of the metal cover is connected with the protection pipe of the capillary and the conductor of the thermal resistance; two sides of the metal cover are provided with a plurality of small holes; when the temperature is measured, a temperature measurement medium passes through the inner hole of the metal cover through the small holes; the indicator display can be obtained by the connection of the capillary and the elastic element, and the conductor is connected with an A/D converter to obtain the number display, having the direct-viewing pointer type display value and the accurate reading number display value.
Description
The utility model is the temperature value that records measured medium by thermal sensing element, removes to export two temperature displayed values by thermal sensing element specifically, the indicated number of a mechanical type dial plate, two dut temperature values that numeral shows.
General at present pressure-type thermometer commonly used shows dut temperature for the dial type pointer, its advantage is directly perceived, but the precision of reading is not high not to be possessed charactron again and shows, and the thermometer of digital display, though beating because of the quick fluctuating of charactron, reading accuracy height, tested temperature value be difficult to resolution directly perceived.
The purpose of this utility model provides the directly perceived and reading accuracy height of a kind of output signal, and output signal can be used for a kind of compound temperature sensor that pressure-type thermometer can be applied to the digital temperature display again.
The technical scheme of taking for the purpose of finishing foregoing invention: at the stationary heat resistance or the thermopair on the kapillary of drawing of thermometer bulb; this thermal resistance or thermopair are protected with metal cap; metal cap one end connects thermometer bulb; one end connects protection tube, and the lead of kapillary and thermal resistance or thermopair all passes through protection tube.Kapillary connects flexible member, makes dial plate produce pointer and shows, the lead of thermal resistance or thermopair connects A/D converter generation numeral and shows.The both sides of metal cap are provided with several apertures, and measured medium can directly be contacted with thermal resistance or thermopair by aperture, make it both to draw mechanical type dial plate temperature and show that the digital temperature of getting back shows.
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the compound temperature sensor structural representation.
According to shown in Figure 1; a kapillary 7 is inserted and fixed in upper end at thermometer bulb 8; on kapillary 7, use tinsel 4 stationary heat resistance or thermopair 5; and be equipped with metal cap 2 and protected, metal cap 2 one ends connect thermometer bulb 8 with screw thread 6, and the other end is connected with protection tube 1; kapillary 7 and lead 3 are all by protection tube 1; kapillary 7 connects flexible member thereupon, makes dial plate produce pointer and shows, the lead 3 of thermal resistance 5 connects A/D converter generation numeral and shows.Two sides at metal cap 2 are provided with several apertures 9, make measured medium can enter the endoporus of metal cap 2 by aperture, thermometer bulb 8 and metal cap 2 insert measured medium, medium feeds metal cap 2 endoporus by aperture, medium synchronous separate does not contact with thermal resistance or thermopair 5 with thermometer bulb 8, both occur the displayed value of pointer-type intuitively on the panel of temperature controller thereby make, and can occur the high digital displaying value of reading accuracy again, formed the dynamo-electric a kind of combined type temperature sensor that combines.
