The Honeywell ABP Series are piezoresistive siliconpressure sensors offering a ratiometricanalog or digital output for readingpressure over the specified full scalepressure span and temperature range.They are calibrated and temperaturecompensated for sensor offset,sensitivity, temperature effects andaccuracy errors (which include non-linearity, repeatability and hysteresis)using an on-board Application SpecificIntegrated Circuit (ASlC). Calibratedoutput values for pressure are updatedat approximately 1 kHz for analog and2 kHz for digital. All products aredesigned and manufactured accordingto lS0 9001 standards.
Dry gases option: The input port islimited to non-corrosive,non-ionicmedia (e.g., dry air, gases) and shouldnot be exposed to condensation.Thegases are limited to media compatiblewith high temperature polyamide,silicone, alumina ceramic, silicon, goldand glass.
Liquid media option:includes anadditionalsilicone-based gel coatingto protect the electronics under port P1, which enables use with non-corrosive liquids (e.g. water and saline) and in applications where condensation can occur. Since port P2 is designed for use with non-corrosive liquids, this option is often suitable for wet-wet differential sensing.

VALUE TO CUSTOMERS
• Simplifies design-in: Small size saves room on the PC board (PCB), or simplifies design in smaller and lower power devices. Meets Moisture Sensitivity Level 2 requirements, which allows for unlimited storage life, when stored inside sealed moisture barrier bag, allows for PCB soldering without any material concern about solder joint quality due to aging of the sensor terminals, which minimizes the concern about aging of the terminals prior PCB assembly. Pressure choices allow engineers to select range required for their application. Leadless SMT, SMT, and DIP package options.
• Cost-effective: Small size helps engineers reduce design and manufacturing costs while maintaining enhanced performance and reliability of the systems they design.
• Accurate: Total Error Band (TEB) and wide pressure range enable engineers to optimize system performance by improving resolution and system accuracy. Optional internal diagnostics validate that the sensor readings are correct.
• Flexible: Supply voltage range, variety of pressure units, types, and ranges, output options, and wide operating temperature range simplify use in the application.
• Versatile: Wet-media compatibility, sleep mode, and temperature output options make the sensor a versatile choice for Internet of Things applications.
• Honeywell Brand: Utilize proprietary Honeywell technology, and are protected by multiple global patents.
• Food Safety Certification for North America, Europe and Asia.
