Sensing Probes for 400 & 500 Series R.F. Capacitance Probes

(5) T.H.D. (Teflon, Heavy Duty)
Used in general purpose and aggressive liquid applications. Standard 1/2″ S.S. center rod insulated with Teflon, 3/4″ N.P.T., max. length 19 Ft., max. temp. 450°F @ atmospheric, max. pressure 500 psig @ 100°F. For use with Model 510, 514, 520 and Cap Analog transmitters.

(6) K.H.D. (Kynar, Heavy Duty)
Used in general purpose liquid application. Generally less expensive than Teflon Insulated probes. Standard, 1/2″ S.S. center rod insulated with Kynar, 3/4″ N.P.T., max. length 15 Ft., max. temp. 400°F @ atmospheric, max. pressure 250 psig @ 100°F. For use with Model 510, 514, 520 and Cap Analog transmitters.

(7) S.T.H.D. (Sanitary, Teflon, Heavy Duty)
Used in food, dairy and pharmaceutical applications that have requirements for C.I.P. (Clean In Place). Design is based on 3-A specifications. Probe construction is a 1/2″ O.D. center rod with Teflon insulation. Mounting requirements are a 1V2″ to 2″ end cap type sanitary fitting which is used with tri-clamp quick disconnects. Sanitary and washdown temperatures to 250°F continually.

(8) T.C.T. (Teflon, Concentric Tube
Used in cylindrical and non-metallic vessels and/or materials with extremely low dielectric values that are free flowing and non-viscous. 1/4″ S.S. center rod with Teflon and surrounded with a 7/8″ O.D. 316 S.S. concentric tube, 3/4″ N.P.T., max. length 12 Ft., max. temp. 450°F @ atmospheric, max. pressure 500 psig @ 100° F.

(9) Dual Probes
Used in liquid applications that are non-conductive or that have a low dielectric value. Also used in applications where there is not an ample earth ground, i.e. non-metallic vessels. Unlike T.C.T, the Dual is used where material is more viscous in nature. Mounting requirements are a 3″ to 5″ flange. Available in both Teflon or Kynar insulation with an insertion length to 15 feet. For use with Model 510, 514, 520, and all Cap Analog transmitters.

(10) T.F./K.F. (Teflon Coated Flexible Cable/Kynar Flexible Cable with weight or turnbuckle anchoring assembly.)
Used in liquids and non-abrasive bulk solid applications. A turnbuckle assembly is used to anchor the sensing probe to a fixed point. Depending on application, sensing cable is available in Teflon or Kynar coatings. Maximum length for liquids 100 Ft., max. length for solids 50 Ft. Mounting requirements are 1″ N.P.T or flange connection.

(11) High Temperature (Lagging Extensions)
Used where process temperatures over 200°F are present, and/or on vessels that are blanket insulated. A 6″ or 12″ lagging assembly is used to recess the electronic unit away from high temperatures. Can be used with all Delavan sensing elements.
