Title: Level switch
Inventor: EBARA KATSUO
IPC: G01F23/26
Filed: 1982-03-13
Abstract: PURPOSE:To detect a liquid surface or level, by detecting an electromagnetic wave from a transmitting antenna in the form of variation in electromagnetic induced voltage at a receiving antenna according to fluctuations of the liquid level or surface of liquid or bulk material to be monitored which contacts the circumference of the transmitting antenna. CONSTITUTION:When the transmitting antenna 3 uses an antenna bar and the receiving antenna 4 uses a receiving coil, a high frequency signal from an oscillating circuit 1 is impressed to the antenna bar 3. When this signal is detected by the receiving coil 4, the voltage induced across the coil 4 varies with the specific dielectric constant epsilon and conductivity sigma of the circumferential material of the receiving coil 4. In other words, the specific dielectric constant epsilon and conductivity sigma of the circumferential material are measured by the voltage V induced across the receiving coil 4. When there is no dielectric material at the circumference, the output voltage V is high. For this purpose, a proper intermediate voltage (v) is set to a voltage comparator 2 to decide on whether the circumferential dielectric material is present or not and to detect the liquid level or surface level.

Abstract: PURPOSE:To obtain fast response by setting an integral value again from the value obtained by subtracting a maximum advance angle of one cycle from a control phase angle within a zero range of a load current and starting normal integration after the current starts flowing. CONSTITUTION:A reciprocal switching circuit 10 places a switch S1 at the side of a contact 3a in one cycle right after the switching of a reversible thyristor to set an internal integral value IA''', to gate block phase integration IAF, and a switch S2 is placed at the side of a contact 2b to perform setting to a gate block angle thetaK, matching a control phase angle with a gate block phase. The switch S1 is placed at the side of a contact 2a in the next cycle to set the IA''' to an integral value IA' calculated by the reverse phase conversion of a phase angle calculated by theta'=theta-theta0, and the switch S2 is placed at the side of a contact 1b to use an arithmetic result theta for the phase control. Then, the switch S1 is held at the side of the contact 2a continuously, so the value IA''' increases at intervals of the amount of integration corresponding to a one-cycle maximum phase advance angle theta0.
