Devices, systems, and methods for interacting instrumentation with high and/or low energy systems are disclosed. In some illustrative embodiments, a sensor assembly for level measurement of high and/or low energy systems may comprise an instrumentation head to determine a level of media in a tank; a coupler including a body having a mounting end for connection to equipment of a high or low energy system and a receiving end for receiving connection of the instrumentation head, a coaxial hardline extending between the mounting and receiving ends and including a conduction tip arranged near the mounting end; and a sealing system including a first seal section disposed between the conduction tip and the receiving end of the body.

In at least one illustrative embodiment, a guided wave radar (GWR) level transmitter may comprise a timing circuit including a first oscillator circuit and a second oscillator circuit, a coincidence circuit configured to generate a coincidence signal indicative of phase shifts created by a difference between first and second frequencies of the first and second oscillator circuits, and a microcontroller configured to (i) determine a stretching factor based on the coincidence signal and at least one of the oscillator signals, (ii) calculate, when the stretching factor is within a first range, a distance to a media surface using the stretching factor, and (iii) adjust, when the stretching factor is outside of a second range, at least one of the first and second oscillator circuits to adjust the difference between the first and second frequencies.

Timing control circuit for guided wave radar level transmitter

An apparatus to detect and measure suspended particles in a molten metal where the suspended particles have an associated noise frequency range has in addition to the electrically non-conductive barrier for immersion in the molten-metal, a device to move the molten metal through an orifice in the barrier and electrodes, a time varying excitation source that generates an AC current at a predetermined range of excitation frequency that is out of the predominant noise frequency range to generate an AC signal that is representative of the measure of the suspended particles. A detector detects and quantifies from the measurement AC signal the suspended particles. The detector can be a synchronous detector.
