| 拉力试验机的传感器，传感器能把被测拉力物理量转换成电信号。 The sensor of the tension testing machine can convert the physical quantity of the measured tension into electrical signal. 传感器可按以下分类： Sensors can be classified as follows: 1、 弹簧传感型式，优缺点：测试传感方式粗糙，测试精度不高，价格相对低廉； 1. Spring sensor type, advantages and disadvantages: the test sensor is rough, the test accuracy is not high, the price is relatively low; 2、“S”型电子传感器，优点：可数字显示，电脑显示，测试精度较高缺点：材料结构单薄，承受拉压力在100KN以下； 2. "S" type electronic sensor, advantages: digital display, computer display, high test accuracy shortcomings: thin material structure, withstanding tension pressure below 100 KN; 3、轮幅式传感器，通过权型数字电路，抓取材料受力变形后引起电阻线性变化而引起的电压变化，可承受较大的拉压力 3. Wheel-amplitude transducer, through weighted digital circuit, can withstand large tension pressure by grasping the voltage change caused by linear change of resistance caused by material deformation under force. 4、液压传感器，最大优点测量量程大，量程小反而不准确。 4. Hydraulic sensor, the biggest advantage of measurement range is large, but the measurement range is small but inaccurate. |
