Description

The FMA5400 and FMA5500 series has been discontinued. Please see the upgraded FMA5400A and FMA5500A Series as a possible alternative or contact our Flow Engineering Department.

The FMA5400/5500 Series electronic gas mass flow controllers provide for controlling the flow of a wide variety of gases from 0-10 SCCM up to 100 SLM. Utilizing heat transfer through a heated tube to measure molecular gas flowrate, the FMA5400/5500 provides measurement of direct gas mass flowrate, without the need to compensate for variations in gas temperature or pressure (within stated limits). They are available in an economical aluminum/brass construction for typical gas flows and a 316 SS construction for applications requiring more corrosion resistance. The FMA5400 series without integral display is supplied with both an analog 0-5 Vdc and 4 to 20 mA output for remote monitoring; the FMA5500 series has both an integral 3-1/2 digit display and analog output. The display is tiltable over 90 degrees for viewing convenience. The display is calibrated standard to read out directly in SCCM or SLM for nitrogen (other gas calibrations available on special order).

The FMA5400/5500 mass flow controllers feature a built-in normally-closed electromagnetic valve for maintaining a constant flowrate regardless of variations in inlet or outlet pressures. The setpoint is controlled either locally via a potentiometer accessible through an access window in the case or remotely via an analog 0-5 Vdc or 4-20 mA signal (field selectable). The FMA5400/5500 series require 12 to 15 Vdc power @ 800 mA maximum, which can be supplied by the FMA545PW wall plug-in socket power supply (24 Vdc power input @ 650 mA is optionally available). The electronics are reverse polarity protected and have a resettable fuse. Model number FMA545C (supplied separately) provides a mating 15-pin “D” connector with 8 feet of shielded cable for accessing the analog output signals and power input connections. The LCD supplied with the FMA5500 series is connected to the lower electronics via a modular plug. The LCD can be remotely located by purchasing an FMA18RC remote cable assembly–you must then build your own assembly for panel mounting the LCD.

Flow ranges specified are for nitrogen or air at 20 psig inlet (up to 50 SLM0 or 25 psig inlet (60 to 100 SLM units) and 0 psig outlet. when used with other gasses, a multiplication factor is used to determine the flow rate, and the digital display must be rescaled in the field.

To request a custom calibration add the gas abbreviation and inlet pressure/outlet pressure as a suffix to the model number.

Calibrations done at ambient (20C/70F) temperature only.

For 316SS add suffix "ST" to the part number, consult Omega Flow Engineering for cost.

*For units powered by 24 Vdc, add suffix “-24VDC” to model number, no additional cost.

For Oxygen cleaned units, add suffix "-O2CLEAN" to the model number; add $125 to the price.
