New High Resolution, Digital Ultra Low
Pressure Sensor
September 2016
All Sensors Corporation of Morgan Hill, California has announced a brand new low pressure sensor, the DLHR Series.
This new devices series offers design engineers superior performance over lower pressure ranges of 0.5 to 60 inH2O,
compared to the DLH. The DLHR 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 DLHR Series is a low pressure sensor with a
high resolution digital output signal that incorporates our ultra stable dual die technology.
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 DLHR Series utilizes All Sensors’ proprietary CoBeam2 TM Technology, allowing greater sensitivity while
reducing package stress and almost eliminating position sensitivity. With the ability to operate at a low, variable supply
voltage from 1.68V to 3.6V, the DLHR 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 0.5, 1, 2, 5, 10, 20, 30 and 60 inH2O pressure ranges, gage and differential.
