Part name: Tank & Fuel line Pressure Sensor
Description:
Eltek Tank&Fuel pressure sensor is suitable for measuring absolute or relative fuel pressure in advanced fuel management and fuel handling systems. It can be assembled in fuel lines or directly in the fuel tank. Chemical resistance to main fuels (diesel, biodiesel, gasoline and E85) 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 electronic circuits are not in contact with the fuel and they are separated from the fluid by a ceramic membrane. 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.
