随着机械自动化的发展,气动技术将更广泛地应用在生产实践中,因而,对气动传感元件提出了更高的要求。在气动技术应用中,信号来源占有重要地位。通常信号是靠按钮或行程开关产生的,但在某些特殊场合,由于受特定条件限制不能安装开关时(如无安装位置,工件压不动开关等),就需要选用气动传感器作为信号来源。现以简单的送料机构为例说明气动传感器在回路中的应用。如图1所示;从上工序来的
With the development of mechanical automation, pneumatic technology will be more widely used in production practice, therefore, the pneumatic sensor components put forward higher requirements. In pneumatic technology applications, the signal source occupies an important position. Usually the signal is generated by the button or the limit switch, but in some special occasions, due to the specific conditions can not be installed when the switch (such as no installation position, the workpiece pressure does not move the switch, etc.), you need to use the pneumatic sensor as a signal source. Now a simple feeding mechanism as an example of pneumatic sensors in the loop. Shown in Figure 1; from the process to
