Universal design for a TVIS vial

<p dir="ltr">The principles for design of the height of the electrode pair are:</p><ol><li>The base of the electrode should not extend below the vertical, cylindrical portion of the vial</li><li>In most practical applications, the fill height of the electrode is unlikely to extend above half of the height of the vertical part of the wall</li><li>The height of the frozen mass should not extend above the top of the electrode, otherwise there will be a non-linear contribution of the measured capacitance from the fringing field</li><li>Combining principles 2 and 3 means that the maximum height of the electrode needs to be no greater than half of the height of the vertical part of the wall.</li></ol><p dir="ltr">The principles for the design of the width of the electrode pair are:</p><p dir="ltr">A. The combined width of the pair of electrodes should be no greater than half the circumference of the external diameter of the vial<br>B. Given the principle-A then the width of each electrodes is determined as ¼ of the circumference of the external diameter of the vial</p><p dir="ltr">With these conditions then a universal clip connector may be designed that has a fixed position at which the pogo pins will connect with the surface of the electrode.</p>
