Single flange level transmitter use common sense

Summary of intelligent single flange level transmitter products.

smart single flange level transmitter for various container measure accuracy of liquid level, density, have both flange and plug-in flange flat, due to the isolation diaphragm is very thin, is the weak link corrosion resistance, so the liquid membrane material with 316 l, hartz C - 276, monel, tantalum, etc. , suitable for different conditions of anti-corrosion requirements, according to the parameters such as concentration, humidity, pressure measured medium suitable for corrosion resistance is given in appendix table reference for reasonable selection. Such as strong corrosion occasion can choose anti-corrosion structure transmitter.

smart single flange level transmitter measuring principle:

working principle of the intelligent high precision single flange level transmitter is when two of the measured medium pressure ventilation with high and low pressure chamber, role in the delta components ( The sensitive element) On isolation on both sides of the diaphragm, the spacer and components on both sides of the filling liquid to measure the diaphragm. Liquid level transmitter is by measuring diaphragm and on both sides of the insulation on the electrodes of a capacitor. When we have different pressure on both sides, to cause measuring diaphragm displacement, the displacement and stress is directly proportional to the difference, so both sides capacitance range, through the link of oscillation and demodulation, is converted into is proportional to the pressure signal.

smart single flange level transmitter applied occasion:

1, viscous medium under high temperature;

2, easy to be crystallized media;

3, with solid particles or suspended solids precipitation medium;

4, strong corrosive or toxic medium;

5, can eliminate the occurrence of pressure pipe leakage pollution environment; Using spacer can be avoided, because of the measuring signal is not stable, often need to supplement of spacer;

6, for accurate measurement interface and density;

7, remote device can avoid different instant media fusion, so that the measured results truly reflect the actual situation of process changes;

8, hygiene demanding situations;

9, such as food, beverage and pharmaceutical industry production, not only requires the transmitter medium contact conform to the hygiene standards, and should be easy to wash, to prevent cross contamination of different mass media.
