The Microcomputer Plastometer is an instrument used for determining the plastometer indices of bituminous coal (including three indicators: plastometer thickness Y, contraction degree X, and volume curve type). The equipped controller consists of two independent systems, allowing simultaneous control of two heating furnaces or individual control of one heating furnace. It is widely applicable in coal, metallurgy, chemical industry, geological exploration, and other sectors.
● Performance Features of the Microcomputer Plastometer:
■ Bidirectional communication between the computer and controller for comprehensive monitoring of the control equipment
■ Automatic control and display of heating temperature for single or dual furnaces
■ Automatic measurement and display of contraction degree for single or dual furnace coal samples
■ Automatic plotting of volume curves for single or dual furnaces
■ Automatic plotting of furnace temperature versus time curves
■ Automatic recording of furnace temperature before and after every ten minutes
■ Alarm at the inflection point of the volume curve to remind operators to choose operations such as start, stop, mute, or run
■ Manual detection of plastic layer data, input via keyboard for computer storage, automatic plotting of upper and lower plastic layer curves, and calculation of plastic layer thickness
■ Automatic calculation of test results, with printout of test records and reports
■ Storage of historical test data for query and printing
