Hi-Res Digital Low Pressure Sensor features internal compensation.

Press Release Summary:

With error compensation performed internally, DLH Series does not require external calculation. Digital output signal incorporates single die, and I²C or SPI output interfaces with 16-/17-/18-bit resolution are available. Offering >0.25% FSS BFSL accuracy, this sensor operates from 1.68–3.6 V supply and utilizes CoBeam2™ Technology for optimal sensitivity while and reduced position sensitivity. Sensors come in 5, 10, 20, 30, and 60 in. H2O pressure ranges, gage and differential.

Original Press Release:

New High Resolution, Digital Low Pressure Sensor

All Sensors Corporation of Morgan Hill, California has announced a brand new low pressure sensor, the DLH Series. The DLH Series provides higher resolution than any other fully compensated low pressure sensor currently available on the market. Like our industry leading DLV/DLVR, all error compensation is performed internally by an advanced ASIC so no external calculation is required.

The DLH Series is a low pressure sensor with a high resolution digital output signal that incorporates a single die. This offers a fully customizable, turn-key solution for design engineers looking for digital pressure solutions. Product highlights include either I²C or SPI output interfaces with 16/17/18 bit resolution, and better than 0.25% FSS BFSL accuracy. The DLH Series utilizes All Sensors' proprietary CoBeam2 TM Technology, allowing greater sensitivity while reducing package stress and position sensitivity. With the ability to operate at a low, variable supply voltage from 1.68V to 3.6V, the DLH Series renders itself a power conscious device well suited for portable applications. This has further implications that the part can operate directly from a battery with excellent performance. Devices are available in 5, 10, 20, 30 and 60 in H2O pressure ranges, gage, and differential.
