Productoverview:
Ross Monte 3051CD differential pressure transmitterThe standard of process connection to 1/2, and is equipped with connected with the valve set of options.Monte Ross valve group in all types of fittings is 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.
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 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).
Three, product application:
The performance guarantee in different conditions of accuracy and stability.The design of flexible CoPlanarTM platform not only provides the ideal solution for your current application requirements, at the same time through the PlantWeb management and field bus technology can meet the technical requirements of your future.Compact and lightweight design with coplanar, advanced performance, low requirement for field inventory Zui, is a model of the inlet pressure in the transmitter.3051 differential pressure transmitter with 301/305/306 valve, can save installation cost of more than 20%.Because Ros emount Inc can be Rosemount transmitter / valve group in the factory integration installation.
Four, proven performance and reliability:
Even in applications under extremely harsh conditions, 3051CD 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.
Five, 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 parameters:
1, the overall performance is: + 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.
