28.XKJC-4A Glial Layer Analyzer

Analyzer Microcomputer Glial Layer

Product Name: Glial layer analyzer

Product Type: XKJC-4A

Scope:

Suitable for measuring the index of glial layer bituminous coal (maximum thickness of plastic layer Y, X, and volume shrinkage of the final curve three indicators) of special equipment. In line with the national standard GB / T479-2000 "Determination of glial layer index of bituminous coal" requirements, it can be widely used in coal, metallurgy, coking coal quality testing department and other industries.

Features:

Using single chip microcomputer automatic control front, the furnace temperature rise speed, with 16 bit high performance AD conversion to the basis of the composition of the precision real-time control system, can according to the national standard requirements for accurate automatic control heating rate, complete each section temperature heating requirements. Measuring accuracy, the operation is flexible and convenient, the performance is stable and reliable.

It can simultaneously control before, after furnace heating speed, but also can be controlled separately before or after the furnace heating rate of the furnace.

Instrument short time off, start again on power can be restored to working condition before the power failure, avoid sample scrapped. There is a strong anti-jamming capability, including loss of power after the restoration, but also to restore lost power before the test period, the required temperature, conduction angle and other operating parameters.

Good temperature tracking characteristics, particularly for large zigzag coal to better reflect its superiority.

Uses nine high-brightness LED display, respectively, before the furnace temperature, time (heating time), after the furnace temperature components.

Thermocouple cold junction temperature of the automatic compensation of thermocouple non-linearity correction of the temperature measurement system may cause various aspects of error were carried out automatically compensated, so that the display error temperature not greater than ± 3 ℃.

With self-diagnostic and alarm functions, a variety of failures can automatically diagnose and show a different symbol error and alarm, and (except Er3 outside) cut off the main power supply.

In line with the national standard GB / T749-2000 "Determination of glial layer bituminous coal index" relevant regulations.
