【Abstract】 The design of sensors for CDY-2 model instrument is based on principles of differential transformer i.e. the information of rock pressure is first converted into electrical signals by sensors, and then measured. The tonnage is directly readout. This instrument is intrinsically safe and integrated calculating amplifier is used. The performance, manufacturing, installation and use of the sensors are detailed in this paper.更多还原
