多年来,莫斯科包乌曼高等技术学校“压力加工机械及其自动化”教研室,在所属实验室里已成功地将变形测定用压力发送器(图1)应用在水压机的试验工作中。这些发送器借助МПО-2型示波器记录液体压力。发送器的感受元件是一个小圆筒1,其表面上贴着基面长20毫米、电阻为200欧姆的工作电阻丝片2。圆筒是发送器的可更换元件。圆筒材料按照预测 Over the years, Bauman High School of Technology in Moscow “pressure processing machinery and automation ” teaching and research room, has been successfully applied in the laboratory deformation transmitter pressure transmitter (Figure 1) in the hydraulic press test work. These transmitters record liquid pressure with the aid of a МПО-2 oscilloscope. The sensory element of the transmitter is a small cylinder 1 with a working resistance piece 2 attached to the surface with a length of 20 mm and a resistance of 200 ohms. The cylinder is the transmitter’s replaceable element. Cylinder material as predicted
