GDI Sensors can measure pressures from 2,000-40,000 psi.

Press Release Summary:

Utilizing thin film titanium oxynitride isolated sense element, Gasoline Direct Injection (GDI) sensors monitor and control fuel and air mixture in combustion chamber versus intake port. They have 17-4 stainless steel pressure diaphragm, operate on 5 Vdc, and provide 0.5-4.5 Vdc linear amplified analog output proportional to pressure. Suited for harsh, high-vibration environments, units have media operating temperature range of -40 to +180°C, and are impervious to EMI.

High Pressure Sensors for Gasoline Direct Injection

Kavlico, a global business unit of Custom Sensors & Technologies (CST) and an operation of Schneider Electric has expanded its range of pressure sensors for passenger vehicles and light trucks with its newly released Gasoline Direct Injection (GDI) sensors which utilizes a thin film titanium oxynitride (TiON) isolated sense element. As gasoline prices continue their rise, automotive manufacturers are continuing to expand the use of gasoline direct injection systems to increase fuel economy and overall engine efficiency.

Overall fuel efficiency can be improved as much as 8% or more when a GDI system is implemented on an engine and fully optimized. These fuel injection systems monitor and control the fuel and air mixture in the combustion chamber versus the intake port. Regulating the amount of highly pressurized fuel within the combustion chamber is the function of Kavlico's GDI sensors.

Robust by design, Kavlico's small-footprint GDI sensors have a 17-4 stainless steel pressure diaphragm. The sensor operates on 5 Vdc and provides a 0.5 to 4.5 Vdc linear amplified analog output proportional to pressure as standard with other custom output options available. The sensors can measure pressures from 2,000 to 40,000 psi. The high accuracy devices are fully temperature compensated and have a media operating temperature range of -40 to +180°C. Capable of operating in harsh, high-vibration environments, Kavlico GDI sensors are impervious to Electromagnetic Interference (EMI).

Flexible by design, custom packaging for high volume applications is available; pressure ports, electrical connections, output, and materials of construction are design parameters that can be tailored to application-specific requirements.
