DL Series - Dual-Line Analog Input Process Meter
DL-AC-S4NE
The Viatran DL meter boasts specifications and functionality that make it one of the most advanced process meters available.
The Model 249'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 [Sealed Top Adjustments] 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 249 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.
Configure your own product according to your requirements and needs. If you are unsure of the configuration, provide us in the notes the necessary information about the existing sensor or product, even a competitor. We will be happy to help you find an alternative Viatran product. If your request is urgent, let us know. We will do our best to help you resolve this situation to your satisfaction as quickly as possible. If we have all the information, we are able to offer a model with minor differences, which is in stock and you can have another product available the next day.
