Capillary type diaphragm seal pressure transmitter is used to prevent pipe directly,

into the transmitter in the medium pressure sensor assembly,

between it and the transmitter is filled with fluid by capillary connecting,

3051GP remote pressure transmitter used to measure pressure liquid, gas and steam,

and then outputs the signal pressure corresponding 4-20mADC transmitted.

3051GP can communicate with each other HART Communicator, through its setting and monitoring.

Our SMT 3051 pressure transmitter-Capillary Level Transmitters,

can work the same as Rosemount transmitter 3051.


Capillary type level transmitter working principle:

 

The double flange remote differential pressure transmitter,

consists of a differential pressure transmitter,

a capillary tube and a double flange with a sealed diaphragm.

The function of the sealing diaphragm is to prevent the medium in the pipeline,

from directly entering the differential pressure transmitter,

and it is connected with the capillary between the transmitter,

and the liquid (usually filled with liquid),

and the diaphragm is slightly deformed when pressed. Deformation displacement or frequency is transmitted to the transmitter,

through the capillary fluid,

which is processed by the transmitter,

and converted to an output signal,

that can be used to measure the flow, level (dp level transmitter), density,

and pressure of liquids, gases, and vapors.

How to calibrate Differential pressure level transmitter for capillary type?

When you use the rosemount transmitter 3051 pressure transmitter, the dp level transmitter,

before you work,

you may need Rosemount capillary level transmitter calibration.

So,

Level calculation for pressure transmitter with the capillary.

That means, you need to learn:

how to do the level calculation for pressure transmitter with capillary? Okay, here’s what you need to know:


Level calculation never changes on a differential pressure transmitter;

once you understand the equation, you can do any other range calculation.

Now, there are several types of DP pressure installations to level measurement

(also called dp level transmitter );

I’ll give you a step by step based on your problem.


The adjustment of the double flange is special.

It is not necessary to manually adjust the zero point and the range.

Generally, the actual pressure is not used for adjustment.

Instead, the transmitter is read and written by HART,

or other protocol hand-held device to set the transmitter measurement.

The purpose of the upper and lower limits.

This completes the tuning of the transmitter.

The actual application of the Communicator,

is the same as other smart meter communication methods.

The transmitter signal line and the transmitter signal terminal

(or the indoor safety barrier intrinsically safe side terminal)

can be directly connected to communicate with the transmitter. Settings.

For the double flange differential pressure transmitter,

there are main parameters,

such as the lower limit of measurement LRV,

the upper limit of measurement URV and the damping time.

The setup is simple and convenient.

Of course, be careful not to exceed the measurement limits of the measurement range.

Pressure transmitter with a capillary or electronic remote sensor?

What are the differences,

between the pressure transmitter with capillary and remote electronic sensors?

Capillary liquid level transmitter

Capillary liquid level transmitter,

in the detection and control system of industrial production processes in petroleum,

chemical, metallurgy, electric power, food, paper,

medicine, textile, etc., detecting liquid differential pressure,

gauge pressure, absolute pressure,

and liquid in open or closed containers The level of the liquid.

The capillary level transmitter converts the measured signal,

into 4~20mA DC output signal

(Intelligent transmitter can carry Hart protocol communication),

cooperate with other unit combination meter,

or industrial control computer to form detection,

recording, control and other industries automated system.


Capillary level transmitter level measurement

The differential pressure level gauge used to measure the liquid level,

is actually the static head that measures the liquid column.

This pressure is determined by the level of the liquid level,

and the density of the liquid,

which is equal to the liquid level above the pressure tap multiplied,

by the density of the liquid and the acceleration of gravity,

regardless of the volume (or shape) of the container.


Remote transmission pressure transmitter

The remote transmission pressure transmitter,

is mainly used to prevent the medium in the pipeline,

from directly entering the pressure sensing component of the transmitter,

and the flange and the transmitter are connected by a capillary filled with fluid.

It can also communicate with HART handhelds and set and monitor through the handheld.

A medium with a viscous medium that is easily crystallized at high temperature.

A precipitated medium with solid particles or suspended matter.

Strong corrosive or highly toxic medium can eliminate the occurrence of environmental pollution,

caused by leakage of the pressure guiding tube;

The instability of the signal requires the tedious,

work of replenishing the spacer fluid frequently.

The continuous accurate measurement interface,

and the density remote transmission device,

can avoid the intersection of different instantaneous media,

so that the measurement results reflect the actual situation of the process change.

In places with high sanitary cleaning requirements,

such as food, beverage, and pharmaceutical industries,

not only the transmitters are required to meet the sanitary standards,

in contact with the media,

but also should be rinsed,

to prevent cross-contamination of different batches of media.
