Rosemount Series 140 Conductivity Sensors • RUGGED CONSTRUCTION withstands high temperature and pressure • TWO MOUNTING CONFIGURATIONS: screw-in and retractable • INTEGRAL JUNCTION BOX allows easy access to field wiring APPLICATIONS The Model 140, 141, and 142 sensors are contacting conductivity sensors intended for the determination of electrolytic conductivity in applications ranging from high purity water to clean cooling water. The sensors are ideal for use in clean, non-corrosive water having conductivity less than about 20,000 uS/cm. For dirty or corrosive sample or for samples having high conductivity, a toroidal sensor such as the Model 228 or 226 is recommended. FEATURES The Model 140 series sensors are available with a range of cell constants, allowing optimum matching of the sensor to the expected conductivity. For low conductivity, choose the Model 142 sensor (available with either 0.01 or 0.1/cm cell constants). For moderately high conductivity choose either the Model 140 or 141 sensors (both available with 0.2 or 1.0/cm cell constants). The cell constant is accurate to within ±5%, so the error in the measured conductivity will be at least ±5%. For higher accuracy, the sensor must be calibrated by the user. A broad range of calibration standards are available. Although the Model 141 and 142 sensors, which have screw-in process connections, are suitable for most applications, the Model 140 sensor has the advantage of being retractable. It can be removed from the process piping without shutting down and draining the line or vessel. The retraction assembly and ball valve must be purchased separately. All three models have 316 stainless steel electrodes and process connections and use either PEEK or PCTFE insulators. A high temperature option allows the sensor to be used at 392°F (200°C). For ease of field wiring, all three models are equipped with an integral cast aluminum junction box.
