It has a data storage function, and historical data can be randomly called, viewed, printed and output as serial data. Phone: 18651882886 (WeChat ID).
The instrument shell is made of dust-proof steel shell and can be placed on the on-site operation platform or control room for use. It is an advanced intelligent instrument specially used for on-line measurement in steelmaking, ironmaking and non-ferrous metals. Through software programming, the screen shows in detail the optional operation prompts for the operator's next step, guiding them to complete the operation process step by step. It can perform real-time signal measurement, thermodynamic formula calculation, display measurement data and curves, and perform optimized data processing, showing the evaluation level of the measurement data. It is equipped with input and output interfaces for peripheral communication, which can be conveniently and quickly matched with external auxiliary equipment such as PLC networks, printers, remote large-screen displays, measurement status indicator lights, buzzers, and conversion box control systems. All kinds of measurement errors during the instrument measurement process, such as the nature of errors like measurement errors and disconnection of the probe signal connection wire, are clearly displayed on the instrument display screen, which greatly facilitates on-site maintenance and repair for users. Various measurement parameters of the instrument, including the graduation number of the supporting thermocouple, measurement time, measurement start condition value, interface parameters, and formula parameters, can be modified and set through keyboard input according to the user's production process requirements, meeting the requirements of different steelmaking processes for users.
