COAXIAL TYPE GWR PROBE

TWIN ROD/CABLE TYPE GWR PROBE

Œ

Each Eclipse probe can be used for vacuum service (negative pressure) but only the Borosilicate



Eclipse is ideally suited to be used on foaming applications but in specific conditions where dense

foam can enter in the stilling well, coaxial GWR probes are not recommended.

Ž

Depends on the spacer material. See model selection 7xD/7xL GWR probe.



For media with

ε

r 1.9 to 10, GWR probe must be mounted between 3" and 6" (75 and 150 mm)

away from the metal tank wall or in a metal cage/stillwell.
