First SensorFirst Sensor presents the new cost-effective Sensortechnics WBI mass flow sensors with ranges of 200 sccm and 1 slpm. According to the company:

  • In addition to unidirectional devices, the WBI series offers bidirectional sensors to measure flows in both directions.
  • The digital flow sensors achieve a very high accuracy over the complete measuring range in the positive as well as negative flow direction.
  • A linear output signal is available via a digital I²C bus interface (analog output on request).
  • The mass flow sensors utilize a very sensitive thermal measuring principle to detect even lowest air and gas flows.
  • The sensors feature a 2.7…5.5 V supply and low power consumption to allow for battery powered portable or handheld applications.
  • The small housings enable space-saving and flexible PCB-mounting and compact OEM device constructions.
