Liquid level transmitter is a kind of transmitter commonly used in many industries, when we choose liquid level transmitter, only have an understanding of the selection of liquid level transmitter, in order to reduce the occurrence of faults during use. How do we choose a level transmitter that suits our working conditions? First, consider the characteristics of the medium: the proportion of impurity components in the liquid medium, whether it is easy to scale, whether there is alcohol, see whether there is a chemical reaction in light, etc., to avoid the later use of the level transmitter to affect the measurement accuracy. Second, consider the environment in which the level transmitter is applied: such as pressure, temperature, and level range, so as to determine the selection range of the level transmitter. For example, their specific fields of application and scope, such as power plants, chemical plants, etc. Third, to know your own signal output requirements, the general output signal is on PLC, DCS or instruments and other devices, then the output signal of the liquid level transmitter must match the input signal of these devices. Common output signals are 4-20mA, 0-20mA, 0-10V, 1-5V and other analog signals. Fourth, to know the power they can provide, liquid level transmitters generally need power, commonly used working power supplies are 24Vdc, 220Vac, uncommonly used power supplies are 12Vdc, 15Vdc, 48Vdc, 110Vac, etc. Fifth, we must know the accuracy requirements: the accuracy of the level transmitter is related to the price, and the specific situation is analyzed, and there is no need to blindly pursue high precision. Sixth, consider the installation method: the opening position, caliber, standard, material, etc. of the liquid level sensor on the installation equipment process. The liquid level transmitter generally adopts threaded installation or flange installation, and the wiring adopts terminal wiring type and is installed on the instrument. Finally, other factors: Finally, we must also consider the selling price of the level sensor, the scale of the level transmitter manufacturer, maintenance and after-sales service, etc. Product consultation, product customization, agent, technical inquiry, quotation, etc. If you have any questions, please contact Xingyi: 400-600-4496!
