As a level transmitter level measurement indicator due to easy installation, high accuracy, long life and other characteristics in engineering applications has been widely used. Level Transmitter in daily use have more input type level transmitter, single flange level transmitter, double flange level transmitter, RF capacitance level transmitters and so on. Level transmitter characteristics and selection due to the type level transmitters more, and each level transmitters in different occasions has exquisite quality level transmitter, our design department and user departments When the daily selection should understand the various features of the product and the level transmitter targeted choice. 1, single flange level transmitter single flange level transmitter with a flat flange and insert the tube flange level transmitter level transmitter, are using the medium to be measured to its own gravity measuring the height of the liquid level. 2, double flanged level transmitter level transmitter is a double flange differential pressure transmitter, in order to avoid directly measured medium provides a reliable measurement diaphragm in contact with the transmitter Methods. 3, input type level transmitter input type level transmitter has leveraged and football style, the principle is based on the principle of hydrostatic and proportional to the height of the liquid measured, using diffused silicon or ceramic pressure sensor hindrance level transmitter manufacturers, will turn the static pressure into electrical signals. After temperature compensation and linearity correction, converting 4-20mADC standard current signal output. 4, RF capacitance level transmitter RF capacitance level transmitter principle is that when the probe with conductive liquid level constitutes a capacitor, in which the metal core level line capacitance probe pole, conductive liquid for another pole capacitor in the middle of the high stability of PTFE, that explore the outer insulation level lines as a medium between the two poles, with the level of change in liquid level probe wire surrounded the area changed, making up across the capacitor The relative area change, when the liquid level rises, the capacitance increases, the RF circuit will change into an analog signal output. Selection points level transmitter level transmitter is now the world face a wide range of selection for the convenience of users, now the selection of the main points are summarized as follows: First, understand that the input signal is what their own characteristics. Like one hundred Changzhou Technology Limited have a full range of level transmitter, there are specifically designed to measure the level of high-performance low-cost but also for the transmitter. Second, understand their requirements for signal output, the output signal is generally on the PLC, DCS or instruments and other devices, then the output signal of the transmitter and the input signal must match these devices. Common output signals 4-20mA, 0-20mA, 0-10V, 1-5V and other analog signals. a third, to understand their own power supply can provide, level transmitters generally requires power hydrostatic level transmitter, commonly used in the power supply has 24Vdc, 220Vac, there is no common power supply 12Vdc, 15Vdc, 48Vdc, 110Vac, etc. Fourth, the installation: level transmitter generally use screwed or flange mounting, wiring using terminal connection type, mounted on the instrument. Fifth, the accuracy requirements: Henan Long Run Automation Systems precision products: CR-60 series, CR-50 series, CR-30 series, the accuracy is 0.1 and 0.2; sixth, as occasion demands, for example power system you have to use CA / CV series of products, other products is not very suitable. Seventh, the size requirements, the increasing miniaturization level transmitter design, miniaturization purpose is to occupy as little space. Intensive course should allow the user to install, there is heat-intensive installation problem, you must reduce internal power dissipation. Therefore, the value of internal power dissipation in the selection should also pay attention.
