Thermal Conductivity Sensor - series 52201, 52401, 52501 • Very fast response time • Easy air calibration process • Low maintenance costs Precise, robust, easy to maintain This thermal conductivity sensor is ideal for high-precision measurements in both dissolved and gaseous phases. Built in stainless steel, the sensor is ideal for harsh plant conditions and high pressures. The measurement range varies from trace to saturation level. Its concept and precise mechanical assembly ensure an optimal performance, a long life cycle and low maintenance costs. Applications • In-line and package analysis • Dissolved and gaseous applications Low detection limits • Very low detection limits in dissolved and gaseous applications • Low drift Precise • CO2, H2 or N2 concentrations are measured continuously • The presence of other gases in the environment does not affect the measurements. Low maintenance costs • One single annual maintenance is necessary • Resistant to high temperature and cleaning in place (CIP) Easy calibration process • Beverage production • Power -steam industry • Pharmaceutical industry Fast response time +/- 30 sec. Hygienic • Hygienic membrane cap Robust • Stainless steel construction: ideal for harsh chemical conditions and high pressures

Thermal Conductivity Sensor - series 52201, 52401, 52501 The sensor operates on the following principle: the gas to measure diffuses from the sample into a micro volume contained in the sensor through a semipermeable membrane, and comes into contact with a gas thermal conductivity detector. The temperature and the change in thermal conductivity induced by the presence of the gas is measured. The duration of a single measurement is too short to get a reliable measure: successive measurements are made, which induce each time a conductivity curve. The average slope of each measurement curve...
