Model 3051 flange type liquid level transmitter is a new type of transmitter produced by our company with the introduction of foreign advanced technology and equipment. The key raw materials, components and parts are all imported. The whole machine has been strictly assembled and tested. The flange The liquid level transmitter has the characteristics of advanced design principles, complete varieties and specifications, and easy installation and use.

Because the appearance of this model completely integrates the structural advantages of the two most popular and widely used transmitters (Rosemount 3051 and Yokogawa EJA), it gives users a refreshing feeling, and it is in line with the traditional series. The product can be directly replaced in installation, and has strong versatility and substitution capabilities. In order to be suitable for the continuous improvement and development of the domestic automation level, in addition to the design of the flange type liquid level transmitter is small and exquisite, it also introduces the intelligent function with the HART fieldbus protocol.

The two pressures of the measured medium enter the high and low pressure chambers and act on the isolation diaphragms on both sides of the delta element (ie the sensitive element), and are transmitted to both sides of the measurement diaphragm through the isolation sheet and the filling liquid in the element. The electrodes on the measuring diaphragm and the insulating plates on both sides each form a capacitor. When the pressures on both sides are inconsistent, the measurement diaphragm will be displaced. The displacement is proportional to the pressure difference. Therefore, the capacitances on both sides are not equal. Through the oscillation and demodulation link, it is converted into a signal proportional to the pressure.
