Abstract

The invention discloses a double-range pressure sensing mechanism which comprises a base. A first pressure sensor is arranged above the base, a sleeve is arranged above the first pressure sensor, a second pressure sensor is arranged in the sleeve, a spring is arranged between the lower end of the second pressure sensor and the upper end of the first pressure sensor, and the range of the second pressure sensor is smaller than that of the first pressure sensor. According to the double-range pressure sensing mechanism, the second pressure sensor and the first pressure sensor are connected with a control unit through wires during installation, the pressure can be measured indirectly through the second pressure sensor if the acting force is small, and the display of the first pressure sensor does not serve as reference, and the pressure can be measured indirectly through the first pressure sensor if the acting force is large, so that a double-range pressure sensor is formed, the pressure sensor utilization range is increased, large and small acting forces can be measured, and the structure is simple.

Description

Double-range formula pressure sensing mechanism
Technical field
The present invention relates to a kind of pressure sensing mechanism, particularly a kind of double-range formula pressure sensing mechanism.
Background technology
In various device, often need at present the setting pressure sensing mechanism, be used for certain object effect force measurement, existing pressure transducer has fixing range, the pressure transducer of single range in use is restricted, can't satisfy the needs of wide range than the pressure transducer of small-range, the sensor of wide range hour is difficult to again accurately measure at acting force.
Summary of the invention
The purpose of this invention is to provide the double-range formula pressure sensing mechanism that a kind of large and small acting force all can be measured, usable range is wide, simple in structure, overcome the deficiencies in the prior art.
Double-range formula pressure sensing mechanism of the present invention, comprise base, above base, be provided with the first pressure transducer, above the first pressure transducer, be provided with sleeve, in sleeve, be provided with the second pressure transducer, be provided with spring between the upper end of the lower end of the second pressure transducer and the first pressure transducer, the range of the second pressure transducer is less than the range of the first pressure transducer.
Double-range formula pressure sensing mechanism of the present invention, the second pressure transducer and the first pressure transducer all join by wire and control device during installation, indirectly measure force value than I by the second pressure transducer such as acting force, the demonstration of the first pressure transducer is not for referencial use, and is larger such as acting force, can utilize the first pressure transducer indirectly to measure, form the double-range pressure transducer, increased the usable range of pressure transducer, large and small acting force all can be measured, and is simple in structure.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Embodiment
As shown in Figure 1: comprise base 1, above base 1, be provided with the first pressure transducer 2, above the first pressure transducer 2, be provided with sleeve 4, in sleeve 4, be provided with the second pressure transducer 5, between the upper end of the lower end of the second pressure transducer 5 and the first pressure transducer 2, be provided with the range of spring 3, the second pressure transducers 5 less than the range of the first pressure transducer 2.
The second pressure transducer 5 and the first pressure transducer 2 all join by wire and control device during installation, indirectly measure force value than I by the second pressure transducer 5 such as acting force, the demonstration of the first pressure transducer 2 is not for referencial use, larger such as acting force, can utilize the first pressure transducer 2 indirectly to measure, form the double-range pressure transducer, increase the usable range of pressure transducer, but large and small acting force is Measurement accuracy all, and is simple in structure.
