Appendix A: Shortening or Lengthening the Sensing Element
CAUTION:
The insulation length of either Flush Sensing
Elements or Insulated Sensing Elements can NOT
be changed. Cable Sensing Elements can only be
shortened. Instructions are included with each unit.
Any changes to probe length after calibration
requires re calibration to ensure proper
operation.
The Need
Sometimes your application calls for probe lengths other
than the standard 18-inch or longer insertion lengths
supplied. Shortening the sensing element is quite simple
and can be done in the field. Lengthening the sensing
element, however, is more difficult because the metal rod,
typically 304 SS or 316 SS, must be welded.
Before making any Adjustments:
1) Read the following instructions thoroughly.
2) Remove power.
3) Disconnect the electronics.
4) Protect electronics from any static discharge.
5) Protect electronics from any heat.
Shortening
The bare metal center rod of the sensing element can be
shortened with a hacksaw. Be careful not to cut either of
the two insulators. See Figure on this page.
In applications using conductive or water-based
materials, shortening is not a problem. Leave a
minimum bare metal center rod length of two (2) inches.
For dry granular materials, such as powder, sand, corn,
clinker, etc., you must leave a minimum bare metal
center rod length of eight (8) inches. Consult the factory
before shortening beyond this point.
Lengthening
To lengthen the sensing element, an extension rod can be
welded onto the end of the bare metal center rod. Make
sure that the extension rod is the same metal as the
sensing element.
An alternate option is to add a pipe coupling and a
section of metal pipe after threading the tip of the
sensing element. In this case, the metal pipe need not be
identical to the metal of the sensing element.
