RS-485 MODBUS only achieved due to physical layer cable displacement sensor devices from different manufacturers is difficult to solve systems coexist in the same issue. To this end, MODICON developed a RS-485 builds on the "application layer protocol" --MODBUS. Protocol specifies the format of the data packet, the command to achieve the like. Any equipment manufacturers, as long as it meets the MODBUS protocol can work in the same system. Uye MODBUS protocol only supports single host, and to achieve a shared channel by polling mode. Magnetostrictive displacement sensor metrological characteristics magnetostrictive displacement sensor main metrological characteristics are: sensitivity, the basic error of Miran displacement sensor, external displacement sensor linearity, hysteresis error, repeatability of measurement characteristics are as follows: Item Specification basic error (% ) ± 0.05 Linearity (%) ± 0.05 return error (%) 0.02 Repeatability (%) 0.02 magnetostrictive displacement sensor metrological characteristics magnetostrictive displacement sensor main metrological characteristics are: sensitivity, basic error, linearity, hysteresis error, Repeatability metrological characteristics are as follows: Item Specification basic error (%) ± 0.05 Linearity (%) ± 0.05 return error (%) 0.02 Repeatability (%) 0.02 ktf displacement sensor, Miran Technology (certified), displacement sensors provided by the Shenzhen Municipal Science and Technology Co., Miran.
