Rosemount Analytical 222 Specifications
Rosemount™ 222
Toroidal Flow Through Conductivity Sensor
Product Data Sheet
July 2017
LIQ-PDS-222
A high performance sensor with ease of maintenance in mind
The Rosemount 222 toroidal flow through conductivity sensor measures conductivity in highly conductive liquids up to 2 S/cm
(2,000,000 μS/cm). A noninvasive flow through design allows for in-line installations without any obstruction to sample and makes
these sensors ideal for use with viscous or fibrous liquids.
Rosemount 222 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.
Corrosion resistant Teflon pipe liner.
Pt-100 RTD included to allow temperature compensated
conductivity measurements.
Operates in process temperatures up to 182 °C (356 °F).
Meet Process Flow Through Requirements
Versatile installation options allows for direct mounting into
1 in. and 2 in. process lines with 150 lb or 300 lb raised face
threaded ANSI B16.5 flanges.
Plugging resistant and suitable for liquids containing high
levels of suspended solids.
