Conductivity Sensor For various conductivity measurement applications Wide conductivity and temperature range Excellent long-term stability Fast response time Integrated RTD for temperature measurement and / or compensation Optimal accuracy Customer-specific sensor available upon request 1) Aggressive media can influence the long term stability. Chemical resistance of the sensor in the end application must be tested by the customer. 2) 2 electrode configuration available upon request The LFS1710 supersedes the LFS117 which is no longer in production 3) For actual size, see dimensions Technical Data Conductivity range:* Cell constant :* Measurement frequency range: Maximum excitation voltage (between pin 1 and pin 6): < 0.7 Vpp (Electrolysis of the analyte has to be avoided) Operating temperature range: Temperature sensor:* Temperature sensor accuracy (dependent on temperature range):* Cu/Ag-wires, PTFE-insulated, AWG 30 DCLFS1710_E2.3.0 | Conductivity | LFS171

Temperature dependence of resistivity: = temperature in accordance with ITS90 Storage temperature: Alternative construction:* Customized over-mold 4) Cell constant is strongly affected by external objects coming close to the front surface of the sensor. 5) Selfheating must be considered The LFS1710 supersedes the LFS117 which is no longer in production * Customer-specific alternatives available I: applied current V: measured voltage T: temperature sensor Product Photo
