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
No pipe reducers are used
Obstructions
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
