The Model 349's small size allows flexibility in tight spaces, while the welded body, stainless steel connector and sealed adjustments ensure protection against contamination.
The “49” series utilizes three sensor technologies to achieve top performance through all pressure ranges. For ranges 0-5 to 0-150 PSI, a silicon piezoresistive sensor provides extremely accurate readings and high overpressure protection. Bonded foil strain gage sensors are more reliable for pressure ranges 200 to 15,000 PSI where transient spikes could destroy a silicon sensor.
For pressure measurement over 20,000 PSI, Viatran developed the “tube” sensor. Made from high strength stainless steel, this sensor ensures high accuracy and durability where diaphragm type sensors can rupture.Model 349 is equipped with electronic linearization, a compensation circuit that corrects for non-linearities in the sensor.
Surface-mount technology (SMT) allows this complex circuitry to be incorporated into a small package and yield a linearity specification of ≤0.1% FSO (optional to 0.05%). Encapsulation of the surface-mount components of the PC board helps to prevent damage from severe vibration with top-mounted and sealed zero and span adjustments. An internal calibration circuit permits easy 2-point calibration without an external pressure source.
Optional performance features of the “49” series include improved accuracy, temperature compensation, special ranging, modified output, and alternate pressure ports.
