Features

  • Zero and span adjustments are accessible from the outside of transmitters
  • Metered gases are divided into two laminar flow paths, one through the primary flow conduit, and the other through a capillary sensor tube
  • Both conduits are designed to ensure laminar flows and there-fore the ratio of their flow rates is constant
  • Two precision temperature sensing windings on the sensor tube are heated, and when flow takes place, gas carries heat from the upstream to the downstream windings
  • Resultant temperature differential is proportional to the change in resistance of the sensor windings
  • Wheatstone bridge design is used to monitor the temperature dependent resistance gradient on the sensor windings which is nearly proportional to the instantaneous rate of flow
  • Output signals of 0 to 5Vdc and 4 to 20mA are generated indicating mass molecular based flow rates of the metered gas
  • The combined gas streams flow through a proportionating electromagnetic valve with an appropriately selected orifice
  • The closed loop control circuit continuously monitors the mass flow
  • output and maintains it at the set flow rate
  • Flow setpoints are controlled either locally or remotely
  • LCD readout built into the top of the transmitters is tilt-able over 90° to provide optimal reading comfort
  • LCD readout is connected to the transducer by a standard modular plug, and is readily removable for remote reading installations
  • Transducers without LCD readout are also available
  • Available with flow ranges from 10 sccm to 1000 l/min
  • Gases are connected by means of 1/4", 3/8" or optional 1/8" compression fittings and 3/4" FNPT fittings
  • Transducer power supply ports are fuse and polarity protected
