DESCRIPTION

The Cummins 3101989 Pressure Sensing Tube is a component designed for use in commercial trucks. Its purpose is to monitor and transmit pressure readings within the truck’s system. This part contributes to the efficient and reliable operation of the vehicle by ensuring that pressure levels are accurately measured and maintained.

Basic Concepts of Pressure Sensing Tubes

A Pressure Sensing Tube is a device used to convey pressure readings from one part of a system to another. In the context of a truck, it functions by connecting to various pressure points within the engine or transmission system, allowing for the measurement and monitoring of pressure levels. The principles behind pressure sensing technology involve the transmission of pressure through a fluid or gas medium, which is then converted into an electrical signal by a sensor. This signal is subsequently used by the truck’s electronic control unit (ECU) to make adjustments as necessary 1.
