How do I calibrate my IP converter?

How do I calibrate my IP converter?

Calibration Procedure :

  1. Inlet air supply to be set at 20 psi in AFR.
  2. Feed 4mA from source to I/P converter.
  3. Observe master pressure gauge , it should show 3psi.
  4. If it is not showing (3psi) adjust I/P ZERO up to obtain the 3psi.
  5. Feed 20mA from source to I/P converter.
  6. Observe master pressure gauge , it should show 15 psi.

What is P to I converter in process control?

An I/P converter is a current-to-pressure transducer utilized in industrial control systems. It is a small module device used in applications to translate a current analog signal (I) into a pneumatic output (P).

How does P converter work?

The I/P converter uses an electromagnetic force balance principle to change electrical signals into pneumatic signals. Typically, a 4 – 20mA input is converted into a 3 – 15pisg output. The operating principle of the I/P transducer is shown below: As shown above, a coil produces the magnetic field.

What type of output does an i P converter have?

A “current to pressure” (I/P) converter converts an analog signal (4 to 20 mA) to a proportional linear pneumatic output (3 to 15 psig).

How do you calibrate a transducer?

To calibrate your software-controlled sensor you will need to:

  1. Connect the sensor to the control software.
  2. Accurately apply zero and full-scale pressure to the transducer.
  3. Using the software, adjust the zero and full-scale output calibration variables until the respective outputs of the sensor are correct.

What is the output of I P converter?

Why are check valves used?

What is a check valve? Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a one-way valve, in which the flow can run freely one way, but if the flow turns the valve will close to protect the piping, other valves, pumps etc.

What type of input does an i P converter accept?

There are two main types of converter on the market, they are I/P converter and E/P converter. I/P converter converts DC direct current signal to pneumatic pressure and an E/P converter converts a voltage signal to pneumatic pressure. I/P most commonly receives a 4-20 mA signal, and E/P takes 0-10V input signal.

What will be the input and output of AI P converter?

The input is 4 to 20mA signal and the equivalent output is 3 to 15 PSI pressure.

How to calibrate I/P converter?

Generally I/P converter is calibrated for standard industrial signals as 4-20 mA input and 3-15 psi output. Refer following steps to calibrate I/P converter: Remove the I/P from the process. If there is any top cover in I/P remove it.

What is the pressure of I/P converter?

I/P converter, milliamp source,pressure source (20 psi),master gauge. Generally I/P converter is calibrated for standard industrial signals as 4-20 mA input and 3-15 psi output.

Do I need to calibrate my i/p or E/P transducer?

Before using your I/P or E/P transducer, they must be properly calibrated in your system. Such things as orientation, supply pressure, temperature and flow rates could affect the output pressure, especially with the use of any of our 500 series units. Please find the instruction sheets (see section 2) for your unit below.

What is an I/P converter used for?

The I/P converter is typically used in electronic control loops where the final control element is a control valve assembly that is pneumatically operated. In most applications the I/P transducer is mounted on a control valve or very close to it in a mounting bracket.
