Embodiment 1

[0013] Such as figure 1 A pressure-type temperature measuring device with lighting function shown includes a temperature bulb, a capillary and an indicator 3, and the temperature bulb, the capillary and the indicator 3 are connected in sequence, and is characterized in that: the watch case 2 of the indicator 3 There is also a lighting device fixed on it.

[0014] When the light is relatively weak, start the lighting device and illuminate the pressure thermometer indicating table 3, and people can clearly read and judge the temperature value, and people can realize a clear temperature value without looking for other power sources such as a flashlight, which is convenient for people. Work brings great convenience.

Embodiment 2

[0016] This embodiment is basically the same as Embodiment 1, except that the lighting device in this embodiment is composed of at least one set of LED lights 1, a switch, and a power supply. The LED lights 1, the switch, and the power supply are connected in series through wires. The switch and the LED light 1 emit light to illuminate the indicating table 3, so that people can clearly read and judge the temperature value, which brings great convenience to people's work.

Embodiment 3

[0018] In the above-mentioned embodiment 2, the LED lamp 1 is installed on the periphery of the watch case 2 of the indicator 3, which can illuminate the indicator 3 more conveniently. The power supply in the above-mentioned embodiment 2 is a button battery or a dry battery. 3. The area is small and requires little light to illuminate, so button batteries or dry batteries are used. At the same time, the use of button batteries or dry batteries does not limit the use environment of the pressure thermometer. The head of indicator gauge 3 of the pressure thermometer is reasonably designed to ensure that the normal operation of the pressure thermometer is not affected, and the indicator gauge 3 is illuminated at the same time to facilitate reading data. The power supply for starting the LED lamp 1 selects button cell or dry battery according to the quantity of the LED lamp 1 and the size of the gauge 3 of the pressure thermometer, and the battery quantity is determined according to...

Abstract

The invention belongs to the technical field of pressure type thermometers, and provides a pressure type temperature metering device with a lighting function. The pressure type temperature metering device comprises a temperature bulb, a capillary tube and an indication meter. The temperature bulb, the capillary tube and the indication meter are connected in turn. The pressure type temperature metering device is characterized by further comprising a lighting device which is installed on the meter shell of the indication meter. A problem of inconvenience in numerical reading in weak light caused by the fact that the existing pressure type thermometers have no lighting device is solved by the pressure type thermometer. Numerical reading is facilitated by the pressure type thermometer via using the lighting device of the pressure type thermometer under the situation of weak light so that work of people is greatly facilitated.

Description

technical field [0001] The invention relates to a pressure type thermometer, in particular to a pressure type temperature measuring device with lighting function. Background technique [0002] At present, pressure thermometers are widely used in power plants, chemical plants, pharmaceutical production, food machinery, papermaking, ships and other places that need to detect and control temperature in the production process and the supporting installation of related machines. It is a mechanical temperature measuring instrument with the widest application range and the most comprehensive performance. However, because the current pressure thermometer has no lighting function, it cannot read normally when the light is relatively dark, and needs to rely on external light sources such as flashlights, which brings great inconvenience to people's work. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the current pressure thermome...
