Abstract
The invention discloses a kind of double upper limit electric contact bimetallic thermometers of high-precision; including scale, watchcase, temperature-sensing probe, bimetal leaf, protection pipe, relay; the scale is in watchcase; the watchcase is connected to one end of protection pipe; the bimetal leaf is in protection pipe; the relay is in protection pipe close to watchcase position; the temperature-sensing probe is connected to the other end of protection pipe; the present invention can accurately measure the temperature of measured matter; long service life; and nonhazardous, no pollution to the environment, use are safer.
Description
Technical field
The invention belongs to thermometer technical fields, and in particular to a kind of double upper limit electric contact bimetallic thermometers of high-precision.
Background technique
Temperature is seven basic one of physical quantitys in the International System of Units, and people's lives production etc. all be unable to do without temperature
Measurement, thermometer is exactly the tool for detecting temperature, and now more is all mercurial thermometer etc., the measurement of these temperature
Accuracy of measurement is not high, and the scope of application is small, and these substances of mercury are poisonous and harmful, is not grown using the time.
Summary of the invention
To solve the above problems, the invention discloses a kind of double upper limit electric contact bimetallic thermometers of high-precision, Neng Goujing
The quasi- temperature for measuring measured matter, long service life, and nonhazardous, no pollution to the environment, use are safer.
In order to achieve the above objectives, technical scheme is as follows:
A kind of double upper limit electric contact bimetallic thermometers of high-precision, which is characterized in that including scale, watchcase, temperature-sensing probe, double gold
Belong to piece, protection pipe, relay, for the scale in watchcase, the watchcase is connected to one end of protection pipe, and the bimetal leaf exists
In protection pipe, for the relay close to watchcase position in protection pipe, the temperature-sensing probe is connected to the other end of protection pipe.
Preferably, the bimetal leaf in protection pipe in the shape of a spiral.
Preferably, alarm is provided on the watchcase.
Preferably, the bimetal leaf is copper sheet and zinc metal sheet.
Preferably, temperature-sensing probe is stated to be stacked by copper sheet and zinc metal sheet.
Preferably, the protection tube material is stainless steel.
The beneficial effects of the present invention are:
The bimetallic that the present invention uses is safer compared to traditional mercury as temperature-sensing element, does not pollute, and relay can be with
Real-time monitoring is carried out to temperature according to the temperature bound of setting, if temperature is more than the upper limit of setting or lower than under setting
Limit, relay will be such that the contact of bound connects, so that alarm is sounded an alarm, it is more safe.
Detailed description of the invention
Fig. 1 is schematic diagram of the present invention.
Reference signs list: 1, scale, 2, watchcase, 3, protection pipe, 4, bimetal leaf, 5, temperature-sensing probe, 6, alarm, 7,
Relay.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
With reference to Fig. 1, a kind of double upper limit electric contact bimetallic thermometers of high-precision, which is characterized in that including scale, watchcase,
Temperature-sensing probe, bimetal leaf, protection pipe, relay, for the scale in watchcase, the watchcase is connected to one end of protection pipe,
The bimetal leaf is in protection pipe, and for the relay close to watchcase position in protection pipe, the temperature-sensing probe is connected to guarantor
The other end of pillar, the bimetal leaf in the shape of a spiral, are provided with alarm, the bimetallic in protection pipe on the watchcase
Piece is copper sheet and zinc metal sheet, states temperature-sensing probe and is stacked by copper sheet and zinc metal sheet, and the protection tube material is stainless steel.
The bimetallic that the present invention uses is safer compared to traditional mercury as temperature-sensing element, does not pollute, relay
Real-time monitoring can be carried out to temperature according to the temperature bound of setting, if temperature is more than the upper limit of setting or lower than setting
Lower limit, relay will be such that the contact of bound connects, so that alarm is sounded an alarm, it is more safe.
The technical means disclosed in the embodiments of the present invention is not limited only to technological means disclosed in above embodiment, further includes
Technical solution consisting of any combination of the above technical features.
