为了保障冲压生产者的人身安全和防止冲压设备事故的发生,近来太原无线电工厂研制成功了一种新型适用于各种压力机械等设备的人身安全保护装置—ZH-A自检式红外光电保护装置。通过生产实践和技术鉴定证实,该装置性能稳定可靠,便于安装,容易调整,特别是具有自检的优点。该装置已分别用在不同吨位的各种类型的压力机上。该装置是在危险区范围预先设置一道或多道不可见光束,一旦操作者的手或肢体以及不透明物体进入危险区而遮断光线时,则这种遮断的光信号就转为电信号,经放大后与启动电
In order to protect the personal safety of stamping producers and prevent the occurrence of stamping equipment accidents, Taiyuan Radio Factory recently developed a new type of personal safety protection device suitable for all kinds of pressure machinery and other equipment-ZH-A self-test infrared photoelectric protection device . Through the production practices and technical appraisal confirmed that the device performance is stable and reliable, easy to install, easy to adjust, especially with the advantages of self-test. The device has been used in different tonnage of various types of presses. The device is preset in the danger zone of one or more invisible light beam, once the operator’s hand or limbs and opaque objects into the danger zone to interrupt the light, then cut off the optical signal into an electrical signal, amplified After starting with electricity
