Some of the more important parameters to be concerned about: the measurement accuracy (the smaller the value, the more accurate), the response rate (the smaller the value, the faster the response), work environment, temperature coefficient (the smaller the value by smaller temperature), work overload power supply. All DRO will need to work smart meter power supply, the power supply mainly DRO: 220Vac; 110 / 220Vac; 85-265VAC / DC switching power supply smart meter technology, 24Vdc (generally customized) smart meter company, 5Vdc (small panel table). Compared with traditional instrumentation, intelligent instrument has the following features: ① automatic operation. The entire measurement process instruments such as keyboard scan, range selection, switch to start closed, collection, transmission and processing of data and display the print so with a microcontroller or a microcontroller to control the operation to achieve fully automated measurement process. Smart meter technology | force measurement since the instrument (certified) | Guizhou intelligent instrumentation to provide the force measured by the Shanghai Automation Instrumentation Co., Ltd. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) is the Shanghai Zhabei District, flow meters leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Since the force measuring device leadership with the staff warmly welcome all inquiries negotiations to create the force measuring instrument since a better future.
