Thermal flow switch FN300 series

for waterfor oilfor gas

The new generation of thermal flow FN series adopts the principle of thermal diffusion. There are two temperature sensors in the probe, one of which is used as a reference. The sensor measures the temperature of the medium, and the other sensor is heated Measuring range -   water - 1…200cm/s(The default display value is calibrated with water, other media need to be specified) Oil - 3…300cm/s Air - 20…2000cm/s repeatability - 1%@<0.6m/s; 3%@1.5m/s withstand voltage - 100bar initialization time - 1…8s Response time - typical value2s. supply voltage - 18...30Vdc No-load current consumption - ≤500mA,exist24VdcWhen power supply switch output -   output type - push-pull (compatible withPNPandNPN), normally open and normally closed can be set S1,S2Output current - <500mA Voltagedrop - <1V Current mode analog output - output classtype - third line0...20mA/4...20mACan be set loadRA - RA≤0.5KΩ Wiring protection - Reverse phase, overload, short circuit protection show -   design - red4 bit8mm high brightnessled display range - -1999…9999 temperature -   Operating temperature - -40…85℃ Medium temperature - -20…85℃
