DLV Series

The DLV Series Mini Digital Output Pressure Sensor is based on the already popular DLVR series pressure sensors. This series offers excellent perfromance over middle pressure ranges of 5 PSI 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.
