Electromagnetic Compatibility Meets CE Requirements: EN 50081-2, EN 50082-2
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 16
Keep conductive objects away from probe to ensure proper performance
Shock Class ANSI/ISA-S71.03 Class SA1
Vibration Class ANSI/ISA-S71.03 Class VC2
