Overview

The 3051DG pressure transmitter will ultimately prioritize safety, reliability, longevity, and durability as its design principles. Like all Rosemount pressure products, the 3051GP pressure transmitter meets a minimum technical specification of 3 σ. The sturdy, durable, and reliable performance that has earned Emerson Process Management transmitters a wide reputation, coupled with intelligent performance, make this transmitter of extraordinary value.

Product Details

1、 Introduction:

　　3051DG pressure transmitterUltimately, safety, reliability, longevity, and durability will be its design principles. Like all Rosemount pressure products, the 3051GP pressure transmitter meets a minimum technical specification of 3 σ. The sturdy, durable, and reliable performance that has earned Emerson Process Management transmitters a wide reputation, coupled with intelligent performance, make this transmitter of extraordinary value.

2、 Working principle:

　　3051DG pressure transmitterDuring operation, the isolation diaphragms and filling fluid on the high and low pressure sides transmit the process pressure to the filling fluid, which then transmits the pressure to the sensing diaphragm at the center of the sensor. The sensing diaphragm of the 3051 pressure transmitter is a tensioned elastic element whose displacement varies with the pressure applied (for the 3051GP pressure transmitter, atmospheric pressure acts as if applied to the low-pressure side of the sensing diaphragm). The 3051AP absolute pressure transmitter maintains a reference pressure on the low pressure side at all times. The maximum displacement of the sensing diaphragm is 0.004 inches (0.1 millimeters), and the displacement is proportional to the pressure. The position of the sensing membrane is detected by the capacitive plates on both sides. The difference in capacitance between the sensing membrane and the capacitor plate is converted into corresponding current, voltage, or digital HART (High Speed Addressable Remote Transmitter Data Highway) output signals.

3、 Features:

The pressure range of Rosemount3051GP pressure transmitter can reach 4000psi. The 3051GP is equipped with a configurable liquid crystal display (LCD) that can display pressure and diagnostic information. Compact, lightweight, easy to install and transport.

4、 Proven performance and reliability:

Even in extremely harsh application conditions, the 3051GP can provide accurate, stable, and reliable pressure measurement results. This design requires a low amount of filling oil, which allows the transmitter to be less affected by temperature and achieve excellent accuracy.

5、 Application flexibility:

The standard process connector is 1/2 "and comes with an option to connect to the valve group. All types of Rosemount valve assemblies are quick install fittings that have been assembled and leak tested, which can save on-site installation costs.

Due to its compact design, it can be directly connected to the process in a small space - achieving a fast, easy, and cost-effective installation process.

The stability of a pressure transmitter is a key indicator of transmitter performance that is time-dependent. Through active simulation testing that exceeds the IEC770 testing standard, the Rosemount 3051 series transmitter has proven to maintain stable performance for over five years even under the most demanding operating conditions.

6、 Product application:

The Rosemount3051TG pressure transmitter is used to measure the pressure of gases, liquids, and vapors, and then convert it into a 4-20mADC current signal output. It is also possible to communicate with each other through the HART375 and 475 handheld controllers for setting and monitoring purposes.

7、 Main features:

1. Continuous work for 5 years without adjustment;

2. The temperature effect can be ignored;

The influence of static pressure can be ignored;

3. Unidirectional overvoltage impact: After 100000 consecutive unidirectional overvoltage experiments, the impact amount is ≤± 0.03%;

4. Complete self diagnostic function;

5. Small and lightweight (standard type 3.9kg);

6. The influence of static pressure is ignored:

When static pressure (working pressure) is applied, the resonant beam with two shapes, sizes, and materials * * undergoes the same deformation, resulting in a frequency change *, and the deviation is automatically cleared (similar to the temperature effect in the formula and diagram).

7. Excellent unidirectional overvoltage characteristics:

The liquid receiving membrane and the membrane box body are processed using * corrugation technology, so that when the external pressure increases to a certain value, the liquid receiving membrane can come into contact with the body *, and the pressure transmitted by the silicone oil to the sensor no longer increases with the increase of external force, thus achieving a protective effect on the sensor.

8、 Technical parameters:

1. The pressure range is from 0-1.5 psi to 0-4000 psi (from 0-10 to 0-27580 kPa);

2. 0.075% reference accuracy, including linearity, hysteresis, and repeatability;

3. The range ratio reaches 100:1;

4. Lightweight and compact size help achieve easy installation and handling;

5. Under actual process conditions, it can achieve a stability of 5 years.
