3.6.2 Performance - Model 705
Specifications will degrade with Model 7xB, 7xD, and 7xP probes and/or Fixed threshold configuration.
Top 24 inches of Model 7xB probe: 1.2 inches (30 mm). Specification for top 48 inches of single rod will
be application dependent.

Electromagnetic Compatibility
Meets CE Requirements: EN 61326
Note: Twin Rod and Single Rod probes must be used in metallic vessel
or stillwell to maintain CE requirement.
Mounting Affects: Twin Rod
Active rod must be mounted at least 1" (25 mm) from any surface or
obstruction. Minimum stillwell diameter for Twin Rod probe is 3".
Single Rod
Nozzles do not restrict performance by ensuring the following:
No nozzle is <2" (50 mm) diameter
Ratio of Diameter: Length is 1:1 or greater;
any ratio <1:1 (e.g., a 2"
× 6" nozzle = 1:3) may require a Blocking
Distance and/or DIELECTRIC adjustment (see Section 2.6.5)
No pipe reducers are used
Obstructions (See Probe Clearance Table, page 47)
Keep conductive objects away from probe to ensure proper performance
