(1) G.A.R. (Guarded, Abrasion Resistant)
Used in powder bulk solid applications that are abrasive in nature. Probe construction is stainless steel with a durable plastic insulator. Rugged stainless steel sleeves protect insulating material from wear. For use with Model 500 and 511 point level switches.

(2) G.I.M. (Guarded, Injection Molded)
Used in general purpose liquids and bulk solid applications Probe construction is a standard 14" stainless steel probe with a durable food-grade plastic indicator. Mounting requirements are 3/4" N.P.T. For use with Model 500 and 511 point level controls. Level to 10 feet.

(3) G.T. (Guarded, Teflon)
Used in general purpose liquid and bulk solid applications. Probe construction is a 316 stainless steel with 1/4" center rod and Teflon insulation. Mounting requirements are 3/4" N.P.T. or flange mount. For use with Model 500 and 511 point level controls. Maximum temperature 450°F, maximum length of 60"

(4) G.F.C. (Guarded, Flexible Cable)
Used when extended insertion lengths are required and/or with heavy or abrasive material, Probe construction is 3/8" 316 stainless steel cable with durable Noryl as a food-grade insulator, Available in lengths up to 50 feet. Mounting requirements are a 4/4 N.P.T. or flange connection. Maximum pressure 125 psig., maximum temperature 300°F. Actual probe length may vary by ± 1%. For use with Model 500 and 511 point level controls.
