1997, 23(1): 9-11.
<Abstract>(75)
Abstract:
Industrial process control is used for operation control of devices,workshops and factories,but combines process control system with information management system,and forms CIPS,with the development of DCS converting to computer network control.This paper describes a kind of CIPS finished at Laohutai Coal Preparing Plant.
Intelligent Measurement of the Working Parameters for Column Flottion Machine Using MPX Series Pressure Sensors
LUO Jie, ZHU Xiang-ji, TAO Luo-cheng
1997, 23(1): 12-14.
<Abstract>(31)
Abstract:
The measurements of the working parameters such as the heights and densities of foam zone and capture zone with Motorola’s MPX series pressure sensors were studied in this paper.The algorithm was derived,and 8098 single chip microprocessor was used to carry out the measurement of these parameters.This instrument is the foundation of the Column Flotation Automatic Control System.

Measurer of Three Phase Synchronous Time for Vacuum Contactor
ZHU Long-ji
1997, 23(1): 47-49.
<Abstract>(60)
Abstract:
In order to solve the problems of difficulty in adapting vacuum contactor’s 3 phase contact acting synchronousness,and unableness to detect when contact touches resistor,a portable digital measurer is developed,which may be used to measure the synchronous time of 3 phase contacts closing or breaking,as well as to measure the micro resistance after contacts close.In the paper,the author details the performance and working principle of the instrument.
