DLV Series
The DLV Series Mini Digital Output Pressure Sensor is based on the already popular DLVR series pressure sensors. This series offers excellent performance over middle pressure ranges of 5 to 60 PSI, compared to the DLVR low pressure range products.
The supply voltage options ease integration of the sensors into a wide range of process control and measurement systems, allowing direct connection to either I2C or SPI serial communications channels. For battery-powered systems, the sensors can enter very low-power modes between readings to minimize load on the power supply
These calibrated and compensated sensors provide accurate, stable output over a wide temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gasses and the like. A SIL-Gel die coating is added for enhanced media protection.

Specification notes
NOTE 1: The span is the algebraic difference between full scale decimal counts and the offset decimal counts.
Pressure Output Transfer Function:
Where,
Poutdig Is the sensor 14 bit digital output
OSdig Is the specified digital offset (gage and absolute = 1,638)
FSS (psi) Is the sensor Full Scale Span in psi
NOTE 2: Total error band comprises of offset and span temperature and calibration errors, linearity and pressure hysteresis errors, offset warm-up shift, offset position sensitivity and long term offset drift errors.
NOTE 3: Shift is relative to 25°C.
NOTE 4: Shift is within the first hour of excitation applied to the device.
NOTE 5: Parameter is characterized and not 100% tested.
NOTE 6: Measured at one-half full scale rated pressure using best straight line curve fit.
NOTE 7: Power-on time is time from power being applied to first available part communications.
