Sensors

Delphi Low Pressure Sensors provide precise measurements of operating pressure in two ranges:

• From -0.54 psig to +0.18 psig (-3.75 kPa to +1.25 kPa gauge)
• From 0 psig to 2.5 psig (0 kPa to 17.24 kPa gauge)
  

Delphi Low Pressure Sensors are designed to perform in harsh environments such as extreme temperatures and vibration, thermal and mechanical shock, and chemical contamination.  They provide voltage output proportional to the gauge pressure in low pressure systems.

Benefits

• Electronic compensation for precise measurements in a variety of environments
• Reliable and robust:
• Low part count
• Automotive grade
• ISO/TS 16949 certified
• Mounting flexibility
• Designed for under-hood environments
• Appropriate for a wide range of automotive and non-automotive applications
   

Features

• Patented direct mount, eliminates need for bracket
• Temperature compensation
• Electromagnetic interference (EMI) protection
• All-silicon technology
• Electronically programmable trim to customer specification
• Low part count enhances reliability

Typical Applications

Delphi Low Pressure Sensors can be used in fuel vapor and air filter pressure measurement applications.  They can also be used for bladder-type occupant sensing applications in vehicle seating programs.
