Differential pressure transmitters are designed to measure pressure before and after the fluid encounters an interruption, such as a filter or pump. However, this pressure instrument can also be used to measure liquid levels.
Where are differential pressure transmitters used?
If its necessary to measure the volume of liquid in a closed vessel, a differential pressure transmitter can also be used. As long as the density of the fluid does not change with temperature variation, the height of the column of liquid can be determined from the pressure, liquid density and gravity.
When would you use a differential pressure sensor?
Finally, differential pressure sensors measure the difference in pressure between two points in a system. Typically, this is because this difference can be used to measure the flow of a liquid or a gas in pipes or ducts. Alternatively, it may simply be used to detect a blockage or seized valve.
How do I choose a differential pressure sensor?
When selecting a pressure transducer, keep these five criteria in mind:Application and measurement type. Common type of pressure measurement include: Absolute, gauge, differential, vacuum, bidirectional, and sealed gage. Pressure range. Process media. Temperature range and installation environment. Accuracy. Output.
What should a differential pressure sensor read?
The multimeter should (typically) display a voltage between 4.5 to 5 volts for the 5-volt reference, a steady 0 volts for the ground wire, and between 0.5 and 4.5 volts for the signal wire.
What is the working principle of temperature transmitter?
A temperature transmitter works by drawing in the current from the remote DC power supply, connected to the sensor input. The actual signal is transmitted as a change in the power supply. To connect the temperature transmitter, only two copper wires are needed.
How do you choose a differential pressure transmitter range?
Fill fluids, specific gravities, and the maximum allowed distance while using a Range 1 transmitter. By dividing the range of the transmitter by the specific gravity of the fill fluid, it will give maximum vertical distance between pressure fittings that the transmitter can handle.
Which is the best pressure sensor?

What are the symptoms of a blocked DPF?
A slight increase in fuel consumption. Increased idle speed. Deactivation of automatic Stop/Start. A hot, acrid smell from the exhaust.
What is the principle of transmitter?
The functional principle of a resistive pressure transmitter is very simple. The pressure sensor converts the mechanical pressure value into a proportional electrical signal. The pressure sensor typically consists of a stable main body and a (thin) diaphragm.
