ＶＯＧＥＬＥ１８００型摊铺机上的料位传感器为接触式磁敏电阻传感器，其结构如图１所示。其作用是，通过改变刮料板马达的转速来调节摊铺机的供料速度，从而保证路面的摊铺质量。由于磁敏电阻的灵敏度很高，因此要求传感器的各传动件必须运动灵活。 该料位传感器的工作过程如
VOGELE1800 Paver on the material level sensor for contact-type magnetoresistive sensor, the structure shown in Figure 1. Its role is to change the speed of the scraper plate motor to adjust the speed of the paver feed rate, so as to ensure pavement quality pavement. Due to the high sensitivity of the magneto-resistive sensor, it is required that the transmission components of the sensor must be flexible in motion. The level sensor working process such as
