Thermal Resistance: High-grade cast iron construction prevents deformation under the intense radiant heat of the burner flame

meeting UL 810 safety standards for pressure-sensitive internal protection

preventing nuisance pressure switch trips and ensuring efficient heat distribution

Accurate Sensing: Maintains a tight set point tolerance

Warrick 3E4A Fitting Els PW 29614 Thermal Resistance: High-grade cast ironThe Warrick 3E4A is a 4 probe electrode fitting engineered for high accuracy liquid level control in demanding industrial environments. Constructed from a rugged cast iron body and featuring a die cast aluminum epoxy coated terminal housing, this 2 1 2" NPT threaded fitting is built to handle pressure tight applications up to 125 psig at 353F. This conductivity based level sensor fitting is optimized for vertical installation in boiler feed systems,
