Product Overview

The FS1L.0.1L.195 from IST Innovative Sensor Technology is a thermal mass flow sensor for liquids. The layout of the sensor is optimised for measurements in dielectric liquids like oil or pure water. It consists of two temperature depending platinum resistors deposited on one chip. The low ohm resistor with a small area is used as a heater, whereas the other high ohm resistor serves to measure the reference temperature. Using a bridge circuit, the differing resistance value of two elements leads to different (self) heating. The (self) heating is dependent on applied voltage, the mass flow and the media in which the sensor is located. Higher voltage increases self heating, a higher flow rate increases cooling. If the self heating is kept constantly by a suitable controller, the voltage increases with higher flow rates and therefore becomes a measure for the mass flow. As a result of this little thermal mass, the sensor has fast heating and cooling response times.
  • Simple signal processing and calibration
  • Response time is less than 100ms
  • No moving parts
  • Excellent reproducibility
  • Excellent long term stability
  • Available with a plastic housing ofØ6mm
  • Measuring range 0.01m/s to 10m/s
  • Temperature range from -30°C to 150°C
  • 3 pins, leads 30AWG, insulated with PTFE
  • Operating voltage range from 0V to 10V at dT = 10 K
