Description：
Productoverview: Ross Monte 3051L flange mounted liquid level transmitterDue to the adoption of ASIC amplifier design to make the packaging becomes small, and the miniaturization of the membrane structure and the flange of the box, this type of weight dropped to half of the original type.ASIC design not only reduces the number of parts, but also improve the reliability of the amplifier. 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). Third, widely used: For the measurement of gas, liquid and vapor pressure, and then turn it into a current signal output 4-20mADC.Can HART375, 475 hand operator to communicate with each other, setting and monitoring through them. Fourth, the 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. Five, technical parameters: The 1. level measurement accuracy of 0.075%; 2. calibration range from 0.25inH2O to 8310inH2O; 3. flat film chip, 2-, 4-, and inch extend type diaphragm; 4. kinds of filling liquid optional, can meet the requirements of different applications; 5. clever and lightweight, easy installation and maintenance; 6. liquid material: 316L stainless steel, Hastelloy, tantalum. Six, selection table:
