Abstract
The invention discloses a series-type full-scale tension sensing device suitable for large-scale variable loads, which is characterized in that it includes: a guide rail, a transmission box, a tension sensor, a clamper, a connecting hook, a connecting rod and a data acquisition system, Rollers are installed at the bottom of the transmission box, and the transmission box can move relative to the guide rail through the rollers; the tension sensors are connected in series through dowel rods in sequence according to the range; each holder is fixed in the transmission box and is located at any two adjacent tension Between the sensors; the connecting hook is connected to one end of the minimum range tension sensor and connected to the transmission box; the connecting rod is connected to one end of the large range tension sensor and protrudes from the through hole on the side wall of the transmission box; transmitter and multiplexer. The invention has the advantages of simple structure and strong applicability, and is especially suitable for full-scale and high-precision measurement of loads with large variation ranges.
Description
technical field [0001] The invention relates to a series-type full-scale tension sensor device suitable for large-scale variable loads, which belongs to the field of electromechanical measurement engineering. Background technique [0002] The tension sensor is a conversion output device that converts the tension signal into an electrical signal. It has the advantages of simple structure, convenient use, low price, and good reliability. It is widely used in engineering and daily life. [0003] Depending on the application, tension sensors usually have different measuring ranges, ranging from a few newtons to tens of tons. At the same time, due to the different structures, sizes and materials of the tension sensors, the tension sensors have different resolutions and minimum measurement values. Large-range tension sensors usually have lower resolution and larger minimum measurement values, which are suitable for measuring large loads; while small-range tension sensors generall...
