LPG & CNG Pressure Sensors

Kavlico, a global business unit of Custom Sensors & Technologies (CST) has recently released a line of liquefied petroleum gas (LPG) and compressed natural gas (CNG) pressure sensors to support vehicles and industrial equipment utilizing alternative fuels.

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. In application, an OEM would design in a Kavlico fuel rail sensor to measure the absolute pressure of the fuel at the inlet of the injectors.

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