TY - JOUR AU1 - Sakaryan, I. AB - IN THE BLAST-FURNACE PLANTS OF THE COUNTRY I. N. Sakaryan A capacitive sensor for monitoring moving buckets of granulated slag on a suspended trolleyway has been de- veloped and is being suecessful!y used at the Enakievsk MetallurgicalPlant. The working principle is based upon the blocking of the oscillations of a generator having a frequency of 100,000 cps as the bucket passes by the antenna of the sensor. An important advantage of the sensor is that it functions without any mechanical contact with the ob- ject being monitored. The sensor is simple to install and to adjust. The operating principle is shown in Fig. 1. The circuitry of the sensor is assembled on two plates (vertical and horizontal), reinforced by brackets. On the vertical plate is the electronic system, mounted on foil-laminated bakelite, and on the horizontal plate is the power unit. The adjustment of the sensor may be accomplish- ed for the most part, under laboratory conditions, but the final tuning is performed after the sensor is install- ed. This procedure consists of the following: turning the axis of capacitor C 2, one attempts to trip the re- lay Re; rotating C 2 in the opposite direction, one at- TI - Capacitive sensor JF - Metallurgist DO - 10.1007/BF00749826 DA - 2004-11-21 UR - https://www.deepdyve.com/lp/springer-journals/capacitive-sensor-Cw99sqLqIh SP - 363 EP - 363 VL - 15 IS - 6 DP - DeepDyve ER -
