在测力上电子拉力机均采用负荷传感器。如需求取较为复杂参数,微机控制电子拉力机是您更好的选择。从性价比来说,选择力量在30T以内的,电子拉力机更有优势。
In force measurement, load sensors are used in electronic tension machines. If you need more complex parameters, computer-controlled electronic tension machine is your better choice. From a cost-effective point of view, the choice of power within 30T, electronic tractor has more advantages.
在结构特点上,目前主要有两种形式,同步带和减速机；在测力上电子万能试验机均采用负荷传感器。液压拉力机主要采用高压液压源为动力源,而电液伺服类拉力机则是采用伺服阀或比例阀作为控制元件进行控制,有些已经采用高精度负荷传感器来进行测力。
At present, there are two main forms of structure, synchronous belt and speed reducer, and load sensors are used in all kinds of electronic universal testing machines. Hydraulic tension machine mainly uses high-pressure hydraulic source as power source, while electro-hydraulic servo tension machine uses servo valve or proportional valve as control element, some of which have adopted high-precision load sensor to measure force.
