Part name: Exhaust Gas Pressure Sensor (EBP)
Description:
Eltek EBP (Exhaust Back Pressure) sensor is suitable for measuring the back pressure in exhausted gas systems to protect engine and turbocharger against overpressures and for the regeneration of DPF (Diesel Particulate Filter). Suitable for PC-LD and Truck applications. Chemical resistance is guaranteed by means of approved materials. The sensitive element is a ceramic element capable of detecting relative or absolute pressure, integrating a signal conditioning IC, which is directly assembled on the sensor. All the active and sensing electonic circuits are not in contact with the exhausted gas. The sensor output is ratiometric with the power supply. Calibration procedure, fault conditions management, ESD and EMI requirements are guaranteed by means of an approved IC according to automotive standards.
General characteristics:
  • Temperature Compensated (3 points)
  • Pressure Compensated (2 points)
  • Custom Calibration by Conditioning IC
  • Analog or Digital Output
  • Automotive Designed
  • HV, RP and Short Circuit Protection
  • Safety and Diagnostic Functions
