Product catalog summary
Overview: The LFS1107 is a conductivity sensor designed for various measurement applications, offering a wide conductivity range and compact size. It features integrated RTD for temperature measurement and compensation, utilizing a 4-electrode measurement system with circular electrodes.
Technical Specifications:
  • Conductivity Range: 10 µS/cm to 200 mS/cm
  • Cell Constant: Typically 0.42 cm-1
  • Measurement Frequency Range: 100 Hz to 300 Hz
  • Maximum Excitation Voltage: < 0.7 Vpp
  • Operating Temperature Range: -30 °C to +100 °C
  • Temperature Sensor: Pt1000 with a coefficient of 3850 ppm/K
  • Measuring Current: 0.3 mA
  • Connection: Cu/Ag-wires, PTFE-insulated, AWG 30; Pt/Ni-wires, Ø 0.2 mm
Temperature Dependence: The resistivity follows IEC 60751 standards, with specific formulas for different temperature ranges.
Storage Temperature: -20 °C to +100 °C
Considerations: The geometry of the application chamber can affect the cell constant and measurement range. Aggressive media may influence long-term stability, and chemical resistance must be tested by the customer.
Pin Assignment: The sensor has six pins for voltage, current, and temperature sensor connections.
Order Information: The sensor is available in different configurations with specific order codes for Cu/Ag and Pt/Ni wire types.
Manufacturer: Innovative Sensor Technology IST AG, Switzerland. Contact details and further information are available on their website.
