Rosemount 3400HT pH / ORP Sensor

The Rosemount Analytical Model 3400HT pH/ORP Sensor is designed for use at high temperatures and is fabricated with a Ryton® body. The sensor assembly is housed in a titanium tube and requires a process connector (PN 23166-00 or 23166-01, ordered separately) for installation. The sensor can be used in a ball valve (ordered separately) for hot tap (retractable) applications. The sensor includes a hemi glass pH electrode bulb, a Teflon® reference junction, and a Pt100 RTD for temperature compensation. Three wiring configurations are available: Variopol connector (3400HTVP), 9.5 inch lead for sensor head junction box mounting (-61), and 15 foot integral cable for connecting directly to an analyzer or transmitter(-62). Junction box kits with preamplifiers (ordered separately) are required if the sensor cannot be installed within 15 feet of the analyzer/transmitter. When used with integral preamp SMART option is standard (option 70). VP8 cable is required for SMART communication.

Rosemount Analytical PERpH-X™ High Performance pH / ORP sensors incorporate several design innovations that prolong the life of the pH sensor in difficult hot processes. High temperatures, fouling, coating and poisoning conditions cause increased deterioration of the glass pH sensing membrane, increased depletion of the reference electrolyte, and increased thermal stress on all sensor components. Use the Model 3400HT/3400HTVP to lower your total cost of ownership and avoid frequent sensor replacement.
