Low cost Kelvin Probe assemblies plug directly into our positioners, no adapter needed.
There were unfortunately many price increases in the past. The last one happend at the beginning of this year in combination with increased minimum order quantity. 4 parameters (tip material, spread and drop plus tip radius) determine the part #. Changing one of these parameters results in the need to order new probe assemblies with different part number.
In April 2010 we did some work on a different concept of building Kelvin probes.
Here is a link to a
new page detailing some of the ideas for a reconfigurable Kelvin probe. We will add more details as we get nearer to production.
Kelvin Probe Assembly
Image at left shows a typical probe assembly. Insert shows drop down of tips,conta cting device under test at about 45 degrees.
Next image shows installation into one of our micropositioners Just move the thumbscrew into vertical position and insert the probe arm into the mounting bracket of the positioner.
Or you could create a 90 degree bend on the positioner side. That would allow for additional vertical adjustment at the expense of some reach.
Kelvin Probe Assembly attached to small micropositionerHere is the distance between magnetic base plate and sharp end of the tips is with positioner (x-axis in center position):

  • PSEM300 82 mm
  • PSEM700 82 mm
  • PSEM050 87 mm
  • PSEM005 95 mm

See this page for the Kelvin Probe installed in our micropositioner range from the tiny PSEM300M to the very largest PSEM005M.
