Ross Monte 3051CG pressure transmitter

Productoverview:
Ross Monte 3051CG pressure transmitter The United States is the flag of the Rosemount transmitter (Rosemont) to create a new standard for pressure measurement technology. Intelligent pressure transmitter in Rosemount transmitter.The Rosemount 3051 pressure transmitter has the operation performance, the There is nothing comparable to this flexible CoPlanarTM platform, and can be upgraded. The performance indexes of new Rosemount 3051 transmitter to ensure the accuracy and stability of the different conditions.
Two, work principle:
When working, the high and low pressure side of the diaphragm and the filled liquid transmit the process pressure to the filling liquid filled liquid, then transmits the pressure to the center of the sensing diaphragm sensor. The sensing membrane is a elastic element of tension, compression and displacement with the change (for GP gauge transmitter, atmospheric pressure as applied in the low voltage side of the sensing membrane.). The low-voltage side always maintain a reference pressure. The sensing membrane Zui large displacement is 0.004 inches (0.1 mm), and the displacement is proportional to pressure. The capacitor plates on both sides of the diaphragm position detection sensor.The difference between the capacitance sensing diaphragm and capacitor plate is converted to the corresponding voltage or current, HART (high speed digital data highway addressable remote transmitter output signal).
Third, proven performance and reliability:
Even in applications under extremely harsh conditions, 3051CG can also provide a pressure measurement result is accurate, stable and reliable. This design requires a low amount of oil filling, so that the transmitter is affected by temperature smaller and achieve excellent accuracy.
Fourth, application flexibility:
The standard of process connection to 1/2, and is equipped with connected with the valve set of options. Rosemount valve fittings of all types are packaged and fully assembled after the leak test, can save installation cost.
The design features of compact, can be in a small space directly with the process of connecting to realize the installation process quickly and easily and cost saving.
Install the stability of five years to reach 0.125%
The stability of pressure transmitter is a key index of performance of the transmitter associated with time. Through the active simulation test IEC770 test standards beyond the Monte Ross 3051 series transmitter has proved its stable performance for more than five years in the harsh operating conditions zui.
Fifth, main features:
1, 5 years of continuous work without adjustment;
2, the temperature effect is negligible;
Influence of static pressure can be ignored;
3, one-way impact: 100 thousａnd consecutive unidirectional overvoltage overvoltage after the experiment affect the amount of less than 0.03%;
4, improve the self diagnosis function;
5, small, lightweight (standard 3.9kg);
6, static effects are neglected:
When a static pressure (pressure), resonant beam deformation two shape, size and material identical to the same, so the frequency change is consistent, so the deviation automatically cleared (figure similar formula and temperature influence).
7, excellent properties of unidirectional overvoltage:
The liquid membrane and the membrane using corrugated box body processing technology of the original, so that the external pressure increases to a certain value, the film can fully contact with the body, silicone oil is transferred to the sensor pressure no longer increase with the increase of external force, so as to achieve the protective effect on sensor.
Six, technical indicators:
1, the overall performance: + 0.15%;
2, accuracy: + 0.075%;
3, differential pressure: the calibration range from 0.5inH2O to 2000psi;
4, check gauge: range from 2.5inH2O to 2000psi;
5, the absolute pressure calibration range from 0.167psia to 4000psia;
6, the process of diaphragm: stainless steel, Hastelloy CR, by Nell R, Ta (CD, CG) and gold by Nell;
7, compact design, strong and lightweight, easy to install.
Seven, selection table:
