GFL-9722
flow sensor
Description Flow Sensor GFL-9722 ceramic based thermal sensor. consists thick-film heating resistors thick-film temperature sensor. Both temperature sensor heating resistors laser trimmed which provides true sensor-to-sensor interchangeability. sensitive parts sensor coated with black polymer, which protects them from harsh environments like aggressive solvents, corrosive gasses aggressive vapors. When GFL-9722 heated heating resistors, flow passing sensor will cool Because this output resistance will change. External temperature effects compensated using second, not-heated, sensor connected Wheatstone bridge configuration. Specifications air, ambient temperature Atm.)
