Industry-leading accuracy: Extremely tight accuracy of
±0.25 %FSS BFSL (Full Scale Span Best Fit Straight
Line):
Allows unlimited floor life when stored as specified
(<30 ºC/85 %RH), simplifying storage and reducing
scrap
Insensitive to mounting orientation:
Allows customers to position the sensor in the most
optimal point in the system, eliminating the concern for
positional effects
Increases flexibility of use within the application
Insensitive to vibration: Reduces susceptibility to
application-specific vibration that occurs with changes in
pressure, minimizing inaccurate pressure readings
Custom calibration: Typically allows for the removal of
additional components associated with signal conditioning
from the PCB, reducing PCB size as well as costs often
associated with those components (e.g., acquisition,
inventory, assembly)
Reduces software needs to correct system
inaccuracies, minimizing system design time
Supports system accuracy and warranty requirements
Helps to optimize system uptime
High burst pressures above 415 inH2O (1034 mbar):
Allows the sensor to endure a wide range of conditions
while maintaining a high level of sensitivity which
measures even the smallest change in pressure
Can simplify the design process
High working pressure ranges above 135 inH2O
(336 mbar): Allows ultra-low pressure sensors to be used
continuously well above the calibrated pressure range
Industry-leading flexibility
Internal diagnostic functions: Increases system
reliability
Energy efficient: Extremely low power consumption (less
than 10 mW, typ.):
Modular, flexible design with many package styles
(with the same industry-leading stability), pressure
ports, and options simplify integration into the device
manufacturer’s application
Available soon: single side liquid media option allows
the end customer to use one port of the sensor with
condensing humidity or directly with non-corrosive
liquid media
Reduces power consumption
Provides extended battery life
Promotes energy efficiency
Output: I2C- or SPI-compatible 14-bit digital output (min.
12-bit sensor resolution) accelerates performance through
reduced conversion requirements and the convenience of
direct interface to microprocessors or microcontrollers;
analog output also available
Repeatability: Provides excellent repeatability, high
accuracy and reliability under many demanding conditions
Onboard signal conditioning: Typically allows for the
removal of signal conditioning components from the PCB,
reducing costs and simplifying production processes
Wide variety of pressure ranges: From ±2.5 mbar to
±40 mbar [±1 inH2O to ±30 inH2O] provide support for
many unique applications
Small size: Miniature 10 mm x 10 mm [0.39 in x 0.39 in]
package is very small when compared to most board
mount pressure sensors:
Occupies less area on the PCB
Meets IPC/JEDEC J-STD-020D.1 Moisture Sensitivity
Level 1 requirements:
Typically allows for easy placement on crowded PCBs
or in small devices
RoHS compliant
Protected by multiple global patents
Allows the customer to avoid the thermal and
mechanical damage during solder reflow attachment
and/or repair that lesser rated products would incur
