Homework Help - Transmitter for dP

In summary, the conversation discussed a homework question about how a normal transmitter, used for measuring differential pressure, can be labeled as FT, PT, or LT in a process scheme. The conversation also mentioned that these labels stand for Flow Transmitter, Pressure Transmitter, and Level Transmitter. The poster reminded the person asking the question to put in effort and provide more context. They suggested considering if a differential pressure can be used as one or more of the three types of transmitters. Answers were welcomed.

Hello.

I've got a last homework before the summer, which is due to be handed in tomorrow.
The question is the following:

"How is it possible that a normal transmitter, used for measuring differential pressure, can get the label FT, PT, LT in a process scheme?"

Of course, the labels stands for Flow Transmitter, Pressure Transmitter and Level Transmitter.

Answers are appreciated!

Hello T4, ##\quad## :welcome: ##\quad## !

Different culture here at PF: we require an effort from the poster (see guidelines)

You also want to add some more context, because I'm pretty sure the answer "because paper is patient" , although correct, doesn't earn you any points.

Start by asking yourself: can a dP be used as one or more of the three ?
 

1. What is a transmitter for dP and how does it work?

A transmitter for dP, or differential pressure, is a device used to measure the difference in pressure between two points in a system. It works by converting the pressure difference into an electronic signal, which can then be transmitted to a control system or display. This allows for accurate and precise measurement of pressure in various industrial processes.

2. What are the main components of a dP transmitter?

The main components of a dP transmitter include a sensing element, a process connection, and a transmitter circuit. The sensing element is responsible for detecting the pressure difference, while the process connection is used to connect the transmitter to the system being measured. The transmitter circuit converts the signal from the sensing element into a usable electronic signal.

3. How is a dP transmitter calibrated?

A dP transmitter is calibrated by comparing its output signal to a known pressure source. The transmitter is first set to zero by adjusting the zero reference point, and then a known pressure is applied to the sensing element. The output signal is then adjusted to match the known pressure, ensuring accurate measurements.

4. What are some common applications of dP transmitters?

Differential pressure transmitters are commonly used in industrial processes such as level measurement, flow measurement, and pressure measurement. They are also used in various industries, including oil and gas, chemical, and water treatment, to monitor and control various processes.

5. What factors should be considered when selecting a dP transmitter?

When selecting a dP transmitter, some important factors to consider include the range of pressure to be measured, the accuracy and precision required, the type of process connection needed, and any environmental factors such as temperature and humidity. It is also important to consider the specific application and any specific requirements or regulations that must be met.
