The AWM40000 Series mass flow sensor family is based on proven microbridge technology and includes both amplified signal conditioned devices and unamplified sensor only devices.,When using the unamplified devices (AWM42150VH and AWM42300V), the heater control circuit and the sensing bridge supply circuit are both required for operation per specification. These two circuits are NOT on board the sensor and must be supplied in the application. The differential amplifier circuitry is useful in providing output gain and\/or introducing voltage offsets to the sensor output.,The amplified devices (AWM43300V and AWM43600V) can be used to increase output gain and introduce voltage offsets. The differential instrumentation amplifier circuitry, heater control circuitry and sensing bridge supply circuitry are all provided onboard the amplified sensors.• Manifold mount\/o-ring sealed,• Ceramic flow tube (non-outgassing), 0 to 1000 sccm,• High common mode pressure (150 psi ceramic flow tube only),• Operating temperature up to 125°C,• High stability at null and full scale• Damper control for heating, ventilation, and air conditioning systems,• Gas analysers,• Low vacuum control,• Process control,• Medical respirators and ventilators,• Oxygen concentrators,• Leak detection equipment,• Vent hoods,• Anaesthesia control,• Gas metering,• Gas chromatographyMedia Monitored = Hydrogen GasDevice Type = UnamplifiedMinimum Flow Rate = -25 sccmMaximum Flow Rate = 25 cm³\/sSupply Voltage = 15 V dcPipe Diameter Range = 0.246 inMaximum Pressure = 150psiMaterial = PlasticMinimum Operating Temperature = -40°CMaximum Operating Temperature = +125°C
