What are differential sensors?
What are differential sensors?
The differential pressure sensor measures the pressure drop between two points in the flow pattern and is used at two different points in the exhaust manifold. At one point it reports the charge status of the particle filter and monitors its function.
What does a differential pressure sensor do?
A differential pressure sensor measures the difference in pressure at two points and provides a comparative measurement between the two.
What is the difference between absolute and differential pressure?
Remember, absolute pressure is measured from absolute zero, atmospheric pressure is the pressure commonly the point of zero on most gauges, gauge pressure is the pressure on a gauge being read from zero, and differential pressure is the difference between two pressures.
What is relative sensor?
Relative Sensors provide measurement to a fixed or variable measurement. For example, a thermocouple, where the temperature difference is measured, not the actual temperature.
Where is the differential pressure sensor?
The DPF differential pressure sensor is usually mounted in the engine compartment to protect it from heat. The sensor is connected to the engine control unit (ECU) by an electrical connector and connected to the DPF via two silicon hoses.
What is a pressure sensor?
A pressure sensor is a device or instrument which is able to measure the pressure in gases or liquids. A pressure sensor consists of a pressure-sensitive element which can determine the pressure being applied and components to convert the information into an output signal.
What causes differential pressure?
Differential pressure is used to determine if a pipeline has any clogs or contaminates as particles flow through orifices and filters. If part of the pipe gets clogged, it will cause a change in the pressure, which causes differential pressure to increase or decrease.
What are analog sensors?
Analog sensors are the devices that produce analog output in correspondence to the quantity being calculated. These sensors also observe the change in external factors such as light intensity, speed of the wind, and solar radiation, and others.
What is absolute and relative sensor?
An absolute pressure sensor measures the pressure in relation to a reference pressure which is the vacuum. A relative pressure sensor refers to the ambient atmospheric pressure and therefore measures the difference between the process pressure and the atmospheric pressure.
