DIFFERENTIATION
• Industry-leading long-term stability: Minimizes system
calibration needs and significantly reduces downtime.
• Industry-leading accuracy: Reduces software to correct
system inaccuracies, which minimizes design time, helps
improve efficiency, and often simplifies development.
• Industry-leading flexibility: Modular design with many
package styles and options simplify integration.
• Total Error Band: Provides true performance over the
compensated temperature range, which eliminates the
need to test and calibrate every sensor, thereby reducing
manufacturing cost. Improves sensor accuracy and offers
ease of sensor interchangeability due to minimal part-to-part
variation (see Figure 1 on page 3).
POTENTIAL APPLICATIONS
• Medical: Airflow monitors, anesthesia machines, blood
analysis machines, gas chromatography, gas flow
instrumentation, hospital room air pressure, kidney dialysis
machines, nebulizers, pneumatic controls, respiratory
machines, sleep apnea equipment, spirometers, ventilators
• Industrial: Barometry, drones, flow calibrators, gas
chromatography, gas flow instrumentation, HVAC clogged
filter detection, HVAC systems, HVAC transmitters, indoor
air quality, life sciences, pneumatic control, VAV (Variable Air
Volume) control, weather balloons
PORTFOLIO
Honeywell offers a variety of board mount pressure sensors
for potential use in medical and industrial applications. Our
categories of pressure sensor measurement include absolute,
differential, gage or vacuum gage, with unamplified or amplified
sensors and covering a wide pressure range.
DESCRIPTION
The RSC Series is a piezoresistive silicon pressure sensor
offering a digital output for reading pressure over the specified
full scale pressure span and temperature range. It is calibrated
and temperature compensated for sensor offset, sensitivity,
temperature effects, and non-linearity using a 24-bit analog-to-
digital converter with integrated EEPROM. Pressure data may
be acquired at rates between 20 and 2000 samples per second
over an SPI interface. It is intended for use with non-corrosive,
non-ionic gases, such as air and other dry gases, designed and
manufactured according to ISO 9001 standards, and is REACH
and RoHS compliant.
VALUE TO CUSTOMERS
• Enhances performance: Output accelerates performance
through reduced conversion requirements and direct
interface to microprocessors. Proprietary Honeywell
technology combines high sensitivity with high burst and
over pressure while providing industry leading stability
(performance factors difficult to achieve in the same sensor),
providing flexibility in implementation and minimizing
requirements for protecting the sensor without sacrificing
ability to sense very small changes in pressure.
• Cost-effective, high volume solution with a variety of options.
• Enhances reliability: High burst pressures promote system
reliability, minimize downtime, and can simplify design.
High working pressures allow ultra-low sensors to be used
continuously above the calibrated pressure range.
• Easy to design in: Package is small when compared to many
similar sensors, occupying less area on the PCB. Port and
housing options simplify integration. Wide pressure range
simplifies use.
• Meets IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level
1 requirements: Allows avoidance of thermal and mechanical
damage during solder reflow attachment and/or repair that
lesser rated sensors would incur, allows unlimited floor life
when stored as specified (simplifying storage and reducing
scrap), eliminates lengthy bakes prior to reflow, and allows for
lean manufacturing due to stability and usability shortly after
reflow.
• Energy efficient: Reduces system power requirements and
enables extended battery life.

Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating voltage.

Compensated temperature range: The temperature range over which the sensor will produce an output proportional to pressure within the specified
performance limits.

Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the pressure range. Includes all errors
due to pressure non-linearity, pressure hysteresis, and non-repeatability.
