RUGGED CAST ALUMINUM WEATHER PROOF JUNCTION BOX provides easy access to field wiring. MEASUREMENT RANGES FROM 0-1 µS/cm to 0-20,000 µS/cm.

FEATURES AND APPLICATIONS The Rosemount Analytical Models 140, 141, and 142 conductivity sensors are designed for measuring conductivity in high temperature and pressure applications. A choice of cell constants allows measurements in low to medium conductivity level samples. Corrosion-resistant 316 stainless steel construction and the ability to be inserted directly into a process line or through the side of a vessel make the sensors rugged and easy to install. The Model 140 retractable conductivity sensor simplifies sensor installation and maintenance because it can be removed from a pressurized line or vessel without shutting down the process or using bypass sample lines. The sensor’s measuring electrodes are inserted into the process through a 1 in. ball valve and a Viton® process seal. To retract the sensor, a retaining nut is loosened, the sensor backed out of the process and the ball valve closed. The standard Model 140 is constructed of 316 stainless steel and PEEK and can operate at up to 150°C. High temperature options (Codes 05, 07, 55, or 57) must be selected to measure up to 200°C. The choice of a 0.2 or 1.0 cell constant allows conductivity measurements up to 20,000 µS/cm with the Rosemount Analytical Models 54C,1054A/B C, 2054C, 1181C, 2081C, 3081C, and 81C analyzers. The Model 141 insertion sensor measures conductivity in high temperature, high-pressure applications. The standard Model 141 is constructed of 316 stainless steel and PEEK and can operate at temperatures up to 150°C. An optional high temperature version (Code 14) can operate at temperatures up to 200°C. The choice of a 0.2 or 1.0 cell constant allows conductivity measurements up to 20,000 µS/cm with the Rosemount Analytical Models 54C, 1054A/B C, 2054C, 1181C, 2081C, 3081C, and the 81C analyzers. The Model 142 low conductivity insertion sensor measures low conductivity solutions at high temperatures and pressures. The standard Model 142 is constructed of 316 stainless steel and Kel-F, and can operate at temperatures up to 150°C. An optional high temperature version (Code 14) can operate at temperatures up to 200°C and is constructed of 316 stainless steel and PEEK. The choice of a 0.01 or 0.1 cell constant allows measurement ranges from 0-1 µS/cm and up to 0-2,000 µS/cm with the Rosemount Analytical Models 54C, 1054A/B C, 1181C, 2081C, 3081C, and 81C analyzers Viton® is a registered trademark DuPont Performance Elastomers.
