The microcomputer calorimeter is divided into two kinds of one-chip computer control and pc machine control. Is one of the commonly used coal testing equipment. It is suitable for the measurement of coal, coke, petroleum, cement, raw materials, bricks and other solids or liquids, etc. Combustible materials such as electricity, coal, metallurgy, petrochemical, quality inspection, environmental protection, cement, paper, geological survey, research institutes and other industries. The calorimeter controlled calorimeter has the functions of automatic water injection, drainage, automatic water temperature adjustment, automatic stirring, auto-ignition, and micro-printer printing results. It is easy to operate and can measure continuously for a long time. Full Chinese menu operation interface, easy to operate. With the function of converting high and low heat after the experiment. The experimental process is automatically cooled and corrected, and the use of ambient temperature is relaxed.
The pc-controlled calorimeter runs on a Windows 98 and above system. Automatic injection, drainage, will not overflow, do not need to adjust the temperature. Using scientific and effective algorithms, automatic correction of constants, high data accuracy. The system is stable and reliable, and data processing can be performed after the test. Using serial communication technology, the failure rate is low. The use environment is loose.
Microcomputer automatic calorimeter system and hardware components Microcomputer automatic calorimeter according to structure and function can be divided into calorimeter body, computer system, measurement system and control system, as described below.
1. Calorimeter body: oxygen bomb, inner cylinder, outer cylinder, etc.;
2, microcomputer system: host, monitor, printer, etc.;
3, the control system: ignition, mixing control and switching circuits, etc. microcomputer automatic calorimeter working principle is the use of sensors that are very sensitive to temperature changes as a temperature measuring element, such as the primary resistance thermometer, quartz or semiconductor thermometer. When the temperature of the thermometer is changed, the physical characteristics such as the resistance and the frequency of the crystal will change accordingly. The change of the precision bridge or other means outputs an analog voltage signal, which is converted by the AID converter after being amplified by the amplifier. As a digital signal, the digital signal is processed by a microcomputer to complete the temperature measurement and control process.
