Kavlico’s Common-Rail Pressure Sensor Provides Improved Power & Torque for Diesel Engines

Kavlico, a global business unit of Custom Sensors & Technologies (CST), has designed a sensor to measure common-rail pressure in diesel engines. The advantages of monitoring common rail pressure are many; including increasing engine power & torque, improving fuel economy, reducing engine noise, and improving vehicle drive-ability while creating cleaner exhaust emissions. With today’s restrictive emissions standards, keeping exhaust particulate emissions within the mandated levels is a must… and Kavlico’s common-rail sensor is an essential element of the common-rail injection system.

Pressure is regulated and monitored by the Electronic Diesel Control Unit (EDCU) which receives an electronic input from the Kavlico pressure sensor. The sensor operates on 5 Vdc and provides a 0.5 to 4.5 Vdc linear amplified analog output proportional to pressure to the EDCU. The highly accurate and ruggedly designed sensor uses a thin film TiON sense element which provides highly reliable and repeatable measurements.

The cost-effective sensor is EMI/EMC protected, has low power consumption, and is capable of operation in high vibration environments. Fully temperature compensated across the entire measurement range, the sensor has an operational temperature of -40°C to 125°C.

Pressure ranges are available from 0 to 3,000 Bar or 40,000+ PSI. The sensor can be customized to accommodate a wide array of pressure ports and electrical connector options dependent upon each OEM application-specific requirement. Alternative pressure ranges and output formats are also available upon request.
