Courtesy: Endress+HauserEndress+Hauser’s Memosens CLS82D conductivity sensor is designed for production, process development and laboratory applications in the pharmaceutical, food, life sciences and other industries. The four-electrode sensor measures conductivity from 1 µS/cm to 500 mS/cm and temperature from 23 to 248 °F (-5 to 120 °C) with accuracy of ≤4% and repeatability of 0.2%. The CLS82D has 316L stainless steel construction, electropolished surfaces, hygienic process connections, and IP68 protection, and it can be sterilized in place (SIP) at temperatures up to 284 °F (140 °C) for clean-in-place (CIP) operations. The sensor is available in a PG13.5 thread size, with 1.5- and 2-in. Tri-Clamp sanitary fittings, or with an NPT fitting, making it suitable for a variety of applications.

The conductivity measuring cell has four platinum electrodes housed in a ceramic sensor element. Similar temperature expansion behaviors of the materials ensure the material bond stays tight even during extreme temperature changes, allowing cleanability and aseptic hygiene. The CLS82D is a digital sensor, so it can store a variety of data in the sensor itself including serial number, data of manufacture, calibration date, number of calibrations, conductivity application range, cell constant, hours of operation at high temperatures, and other data quantifying operating history.
