Abstract
The utility model provides a weighing machine, comprising a sensor shield and a bottom casing. The sensor shield is arranged on the bottom casing, and a heating module is arranged in the bottom casing. According to the weighing machine provided in the utility model, the temperature can rise rapidly, the weighing machine is stabilized fast, and the preheating time for power-on waiting is substantially minimized.
Description
Technical field
The utility model relates to meter and resets technical field fully, particularly a kind of weighing machine.
Background technology
The high precision weighing machine (electronic scales) that pressure transducer is done, after the start power supply, because circuit has the reason of electric heating (especially sensor electric heating), can be because the electric heating temperature rise causes sensor output value, thereby influences the degree of accuracy of weighing machine.This temperature rise time is wanted 30 minutes at least.Total system just can be stablized in 30 minutes.This time period, can accurately not measure.
The utility model content
The utility model provides a kind of weighing machine that can be rapidly heated.
To achieve these goals, the utility model provides following technical scheme:
A kind of weighing machine comprises: sensor mask and drain pan, said sensor mask are installed on the said drain pan, are equiped with heating module in the said drain pan.
Preferably, be equiped with pressure transducer on the said drain pan, said pressure transducer is positioned at said sensor mask, and said heating module is positioned at said pressure transducer side.
Preferably, said heating module comprises: circuit board, heating resistor and temperature sensor, and said circuit board connects the MCU of said weighing machine, and said heating resistor connects said circuit board, and said temperature sensor connects said MCU.
Through implementing above technical scheme, have following technique effect: the weighing machine that the utility model provides, can be rapidly heated, make the fast and stable in this weighing machine, significantly reduce the preheating time of booting wait.
Description of drawings
The structural representation of the weighing machine that Fig. 1 provides for the utility model embodiment.
Embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of weighing machine, and is as shown in Figure 1, comprising: sensor mask 102 and drain pan 109, said sensor mask 102 is installed on the said drain pan 109, wherein, is equiped with heating module in the said drain pan 109.Also be equiped with pallet 101 on this sensor mask 102.
In the present embodiment, more preferably, be equiped with pressure transducer 104 on the said drain pan 109, said pressure transducer 104 is positioned at said sensor mask 102, and said heating module is positioned at said pressure transducer 104 sides.More concrete, said pressure transducer 104 is provided with sensor stand 103, and said sensor mask 102 is installed on the said sensor stand 103.
In the present embodiment; More particularly; Said heating module comprises: circuit board 108, heating resistor 105 and temperature sensor 106; Said circuit board 108 connects the MCU (microprocessor) 107 of said weighing machine, and said heating resistor 105 connects said circuit board 108, and said temperature sensor 106 connects said MCU107.
After drain pan and sensor mask install, form a totally enclosed space.In this space, be equiped with pressure transducer and heating module.The heat that heating module produces makes the air in this totally enclosed space, heats up rapidly, thereby pressure transducer is heated up rapidly.When the temperature inductor of heating module detects temperature and reaches design temperature, send signal to MCU, MCU stops the heating resistor heating according to this signal instruction circuit board, when temperature is lower than design temperature, and the heating of MCU instruction circuit plate control heating resistor.This heating temp is produced by electric heating much larger than pressure transducer temperature makes pressure transducer settle out rapidly.Ignored the influence of the electric heating of pressure transducer own.
More than a kind of weighing machine that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
