The ELVA Series Pressure Sensors are based on All Sensors’ ultra low pressure CoBeam2 TM Technology. This innovative sensing element technology provides pressure sensors with best in class ultra low pressure sensing which reduces pack­age stress susceptibility, resulting in improved overall long term stability and vastly improved position sensitivity.

 

The ELVA series gives design engineers outstanding flexibility with the variety of choices in package combination.

 

The digital interface eases integration of the sensors into a wide range of process control and measurement systems, allowing direct connection to serial communications chan­nels. For battery-powered systems, the sensors can enter very low-power mode 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 gases. A protective parylene coating is optionally available for moisture/harsh media protection for pressure ranges starting at ±25 mbar and above.

Specification notes

NOTE 1: Pressure ranges in Pa and kPa are expressed as an approximate value.

NOTE 2: Differential Proof Pressure: The maximum pressure which may safely be applied to one port of the product for it to remain in specification once pressure is returned to the operating pressure range. Exposure to higher pressures may cause permanent damage to the product.

NOTE 3: Differential Burst Pressure: The maximum pressure that may be applied to one port of the product without causing escape of pressure media. Product should not be expected to function after exposure to any pressure beyond the burst pressure.

NOTE 4: Common Mode Pressure: The maximum pressure that can be applied simultaneously to both ports of a differential pressure sensor without causing escape of pressure media. Product should not be expected to function after exposure to any pressure beyond this maximum pressure.

NOTE 5: Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure.

NOTE 6: Accuracy is the measured deviation based on Best Fit Straight Line (BFSL).

NOTE 7: Total Error Band is calculated from a combination of all possible errors, including offset, span temperature, calibration, linearity, pressure hysteresis, offset warm-up shift, offset position sensitivity, and long term offset drift.

NOTE 8: Parameter is characterized and not 100% tested.

NOTE 9: Max. delay time between pressure change at the pressure die and signal change at the output.
