Pressure transmitters are devices, designed for pressure measurement in gases, liquids, air, or oil. Pressure transmitters are widely used in various industrial processes, such as filtration plants, chemical feeds, wastewater industries, food industries, pumping stations, and more.
Pressure Transmitters Pressure transmitters are used to measure the pressure or level of industrial liquids and gases. The output is transmitted to a control system. Accurate and stable process measurements ensure the safe, reliable, and profitable operation of your plant.
The line includes transmitters that can measure differential pressure, absolute pressure, and gauge pressure. Accurate level readings are essential to the safe, reliable, profitable operation of your plant. Liquid Level transmitters measure differential pressure to infer the level in a vessel.
Hydrostatic pressure transmitters – often called level transmitters because of their working principle and ability to measure level. Hydrostatic pressure transmitters work on the basis that the amount of pressure increases with depth. These devices are submersible and can be used for liquids and gases.

Where are transmitters used?
They are used to measure the pressure drop across an oil filter for example. They are also popularly used to measure flow or level in pressurized vessels. Level transmitters are used to measure the level of a liquid or solid material within a vessel or space.
Where are pressure sensors used in real life?
Pressure sensors are used for many automotive, medical, industrial, consumer and building devices, which depend on accurate and stable pressure measurements in order to operate reliably.
What are the 4 types of pressure transmitter?
Pressure sensors are used for control and monitoring in thousands of everyday applications. Pressure sensors can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude.
What is transmitter range?
Range:is the measurement limit and covers from the minimum to the maximum pressure that the transmitter can measure, e.g., 0 to 5080 mmH2O. The maximum span is 5080 mmH2O. Zero:is the smallest pressure at which the transmitter was calibrated.
What is span limit of pressure transmitter?
Span – The difference between the lowest point and the highest point in a configured measurement range. (For example, if a 250 psi transmitter is adjusted to measure a range of 50 psi to 200 psi, then the span is 150 psi.)
How do you calculate range and span?
Span (Range Calibrated) : It is the work range where the calibration is done is known as span, for example, from 500 to 3000 mmH2O, where the span is 3000-500 = 2500 mmH2O. The Span is equal to URV – LRV.
What is span in level transmitter?
The span of a transmitter is the difference between the 100% and 0% calibration values. Differential pressure transmitters have specified minimum and maximum spans. For example, a given differential pressure transmitter may be calibrated with spans between (say) 400 mmWC and 4000 mmWC.
What is the span of a sensor with range?
Span is the difference between the lowest and the actual reading or output signal of a measurement device. For example a 1.6 bar pressure transmitter maybe re-scaled to read 4mA at 0.8 bar and 20 mA at 1.2 bar. In this example the pressure transmitter would be described as having a span ranging from 0 to 0.4 bar.
What is LRV and URV in instrument?
range-value, lower (LRV) : The lowest value of the measured variable that a device is adjusted to measure. range-value, upper (URV) : The highest value of the measured variable that a device is adjusted to measure.
What is the range of pressure transmitter?
The Pressure Transmitter is calibrated to provide a current range of 4 to 20 mA for a Process Pressure range of 0 to 350 psi.
How do I set the range on a DP transmitter?
Range = URV – LRV = -70 – (-520) = 450 mmwc So, we have to set Lower Range Value (LRV) = -520 mmwc and Upper Range Value (URV) = -70 mmwc in the DP Transmitter using HART communicator.
How do I choose the right pressure sensor?
Span – The difference between the lowest point and the highest point in a configured measurement range. (For example, if a 250 psi transmitter is adjusted to measure a range of 50 psi to 200 psi, then the span is 150 psi.)
