MTI Capacitance Probe Construction Techniques

• Our probes are constructed in-house and go through a stringent quality control process before being released to our customers. We construct them out of different materials to meet whatever demanding application they may be implemented in. You can see here three of our probe styles that we manufacture. On the left we have a standard probe, middle is the push-pull design for measuring non-grounded targets, and right is an advanced construction assembly that allows for virtually flat probes using circuit board manufacturing techniques.
  Each of these have their own specific uses and applications. The standard probe we can measure to a grounded conductive target. This is commonly used for gap measurements, and once calibrated in factory, can provide consistent data that always reflects the actual gap reading. No need for calibrations in situ once calibrated in factory they will give you exactly the data you need.

Our push-pull probes are used in situations where there is a conductive target, but it is not or cannot be grounded and remains isolated. These probes generate a field by using one of the two probe faces to drive a signal to the conductive plate, and the other to measure. This allows the use of non-grounded conductive targets to get distance measurements.
While these two probe types can be manufactured in a variety of materials, advancements in PCB technology allows for the manufacture of accurate thin and flexible probes. This probe construction method allows the probes to go in places that will not tolerate any other probe shapes. In particular, flex designs, are very very thin. They can be one of the features of being so thin is they can actually be formed to contour to shapes
