Kavlico's LPG and CNG Alternative Fuel Pressure Sensors

SENSORS:  Kavlico, a global business unit of Custom Sensors & Technologies (CST) recently released a line of Liquified Petroleum Gas (LPG) and Compressed Natural Gas (CNG) pressure sensors to support vehicles and industrial equipment utilizing alternative fuels - a growing market around the world.

Alternative fuels are no longer a novelty but a bona fide alternative to gasoline and diesel fuels.  These fuel options are being adopted by municipalities and other governmental agencies as an option for fleet vehicles such as cars, buses, truck and other service vehicles such as fork lifts.

Typical applications would include monitoring and measuring low pressure for fuel rail, high pressure for tank pressure, or combined pressure and temperature. The sensors are utilized to optimize fuel metering and control combustion, improving emissions and engine performance.  The OEM will design in a Kavlico fuel rail sensor to measure the absolute pressure of the fuel at the inlet of the injectors.

Kavlico’s robustly designed stainless-steel LPG & CNG sensors utilize a thin film (TiON) sense element and are available in pressure ranges up to 250 BarG. Operating on 5V dc, the sensors provide a linear amplified analog output of 0.5 to 4.5V dc proportional to pressure. Operating temperature range is -40 to 140C across the full operating range. The lightweight sensor can be configured with a variety of electrical and process connections to meet each OEM’s application specific requirement.
