Product Data Sheet
June 2017
LIQ-PDS-245
A noninvasive sanitary sensor for high conductivity applications
Rosemount 245 toroidal conductivity sensors feature a noninvasive flow through design allowing for in-line installations without any
obstruction to sample flow. These sensors are ideal for use in viscous, abrasive, or fibrous liquids and are intended for use in the
pharmaceutical, biopharmaceutical, and food and beverage industries

Rosemount 245 Toroidal Flow Through Conductivity Sensor
Overview
High Performance and Reliability
Robust measurements - insensitive to process flow rate and
direction.
Avoid accumulation of solids with no part of the sensor
protruding into the sample flow.
Steam sterilizable up to 130 °C.
Meet Flow Through Installation Requirements
Available with 0.5, 1.0, 1.5, and 2 in. Tri Clamp connections.
Liner and O-rings meet FDA and USP Class VI requirements.
Plugging resistant and suitable for liquids containing high
levels of suspended solids.
