Abstract
A face wind speed probe comprises a gas measuring module and a display module, the gas measuring module comprises a face wind speed module and a temperature compensation module, the face wind speed module is circular, a circular hole is formed in the middle of the face wind speed module, a temperature control element is arranged in the circular hole, the face wind speed module is connected to the temperature compensation module, and the temperature control element in the circular hole is used for guaranteeing the fact that the face wind speed module is in a constant temperature state. When gas measuring is carried out, heat of the face wind speed module can be taken away by gas flow, the temperature of the face wind speed module declines, after the temperature control element detects the temperature decline of the face wind speed module, compensation signals are sent to the temperature compensation module, the temperature compensation module is a compensation circuit, the compensation circuit generates corresponding compensation currents according to the declined temperature, the compensation currents are fed back to the face wind speed module to enable the face wind speed module to maintain constant temperature, meanwhile, the display module measures the size of the compensation currents, the numerical values of wind speed are displayed on an electronic screen after corresponding coefficient conversion is carried out, precision is higher, and errors are smaller.
Description
Technical field
The present invention relates to gasmetry field, relate in particular to a kind of face wind speed probe.
Background technology
Common face wind speed probe in the market, mostly adopt a feeler lever to be used as surveying the element of wind speed, feeler lever can be followed wind and be swung in use, the amplitude size that feeler lever swings can embody the size of wind speed, because the swing of feeler lever is difficult to see clearly, after simple mechanical connection, can adopt mechanical dial plate directly to indicate wind speed, but the shortcoming of mechanical dial plate is accurate not, the reading that detects by an unaided eye easily produces very large error, is also difficult to the trickle wind speed of reaction and changes.
Summary of the invention
The present invention aims to provide a kind of face wind speed probe.
For achieving the above object, the present invention by the following technical solutions, a kind of face wind speed probe, comprise gasmetry module and display module, described gasmetry module comprises face wind speed module and temperature compensation module, described face wind speed module is circular, middle part is provided with circular hole, in circular hole, be provided with temp-controlling element, face wind speed module connects temperature compensation module, temp-controlling element in circular hole is used for guaranteeing that face wind speed module is in temperature constant state, in the time carrying out gasmetry, air-flow can be taken away the heat of face wind speed module, the temperature of face wind speed module is declined, now temp-controlling element detects after the decline temperature of face wind speed module, send compensating signal to temperature compensation module, temperature compensation module is a compensating circuit, compensating circuit produces corresponding offset current according to the temperature declining, compensation current feedback to face wind speed module makes face wind speed module keep constant temperature, display module is measured the size of current of compensation simultaneously, after corresponding coefficient transforms, the numerical value of wind speed is presented in electrical screen.
As preferably, described electrical screen adopts LED screen.
In order to solve the coarse problem of reading of conventional face wind speed probe, the present invention adopts the test the speed mode different with face wind speed probe in the past, by script simply machinery test the speed and transfer electronic speed-determination to, precision is higher, error is less.
