摘要： A probe comprises a plurality of longitudinally extended conductors forming a probe electrode, a laterally displaced ground electrode and two laterally displaced active guard electrodes interposed between the probe electrode and the ground electrode. The conductors are surrounded by solid insulation and the probe guard electrodes are driven at substantially the same potential as the probe electrode. The probe is utilized to measure the condition of materials in which the probe is immersed.

摘要： A two-wire, admittance-responsive instrument system in which a transmitter, receiver and calibrator are connected by a two-wire transmission line is disclosed. The calibrator repetitively transmits a calibration enabling signal causing the transmitter to increment a reference admittance for comparison to a sensed admittance corresponding to a known physical condition. The calibrator monitors the bistable output signals transmitted by the transmitter in the calibration mode, which changes state when the incremented reference admittance bears a predetermined relationship to the sensed admittance. The calibrator may then transmit additional calibration enabling signals causing preload to be established for transmitter operation.

摘要： A multiple set point material condition monitoring system is responsive both to the level of material with respect to a sensor and the extent of material coating which has accumulated on the sensor. The system provides an output when a predetermined coating thickness has been exceeded, so that the sensor may be cleaned before the coating can accumulate to the extent where a false level output is generated. The systems include three electrode guarded sensors, a bridge comparing the sensor output with a reference, and a bridge reference which is automatically and repeatedly caused to assume a sequence of values corresponding to material condition set points, one of which causes an output when a predetermined coating thickness has occurred and another of which generates a level output. In one embodiment, separate outputs are provided corresponding to each set point. In another embodiment, a single tri-state output is responsive to both set points.

摘要： A probe developing an admittance with a material whose condition is to be continuously measured is capacitively coupled with a variable frequency oscillator, preferably one having a digital output stage, for generating a variable frequency signal having a period varying with the admittance developed at the probe. Both the oscillator input and output are capacitively coupled to the probe. In a preferred embodiment, a set point circuit including a plurality of resistors coupled in parallel with the oscillator output and a plurality of switches coupled in parallel with the probe conductor and each with a different one of the resistor, provides easy circuit adjustment for use of the system with a variety of materials. A preferred digital circuit employing a pair of flip flops, fixed timer and one shot generate a fixed period variable duration duty cycle digital voltage level signal for transmission, if desired, or for conversion into a variable current signal.

摘要： A multiple set point material condition monitoring system includes a material responsive sensor developing a material condition dependent admittance and a reference admittance generator, generating a plurality of different admittance values in a predetermined sequence repeatedly during operation of the system. The circuitry coupled with the sensor and the reference admittance generator outputs a signal which is a function both of the material condition generated admittance and each of the plurality of reference admittance values, in sequence. Storage means are provided for storing a characteristic of the output signal for feedback to the circuitry when that particular reference admittance value for generating that output signal is again generated by the reference admittance generator. Preferably, the sensor and reference admittance generator are coupled across each of a pair of arms of bridge network which constitutes part of the circuitry developing the output signal.

The torque generating wheel has peripheral circumferential veins of spaced magnetic or non-magnetic keys which are driven by an electro-mechanical control system including a plurality of electromagnetic coils and a timing circuit. The timed activation of the electro-mechanical control system on the magnetic (or non-magnetic) keys accelerate the generating wheel to rotate at a high rotational speed to generate a high level of torque output.
