UHZ-50/S-UR/UB series plug-in magnetic float level transmitter

Overview

       1. UR series plug-in magnetic float transmitter

       The liquid level transmitter uses a floating ball with a ring-shaped magnetic steel to rise and fall with the liquid level, so that the reed tube in the main tube is attracted, and the liquid level is converted into a corresponding resistance output. The output resistance is matched with the factory's intelligent digital display instrument. Realize the remote measurement, alarm and control of the liquid level.

       2. UB series plug-in magnetic float transmitter

       The liquid level transmitter is based on the UR series liquid level transmitter. The output resistance signal is processed by a special module (ie, electronic amplifier) to convert the resistance signal into a two-wire 4-20mA signal output that can be directly connected with DDZ -Ⅲ The electric unit instrument is matched to realize remote measurement, alarm and control. It can also be matched with the intelligent digital display instrument produced by our factory.

       The plug-in magnetic float level transmitter is used in the chemical industry, electric power, papermaking, shipbuilding, environmental protection, food and other industries. It is used to measure the liquid level of the medium in the pressure (open) container. It is used for the liquid level of underground tanks, pools, and high-rise water tanks. Position measurement is simpler, more reliable and ideal. The plug-in liquid level transmitter is made of stainless steel, corrosion-resistant, suitable for flammable and explosive places.

working principle

       The main pipe of the in-type magnetic float level transmitter is equipped with a set of reed pipes and precision resistors. When the float with ring magnets outside the pipe changes with the liquid level due to buoyancy, it is located at the liquid level in the main pipe. The dry reed switches are sequentially closed (connected) under the action of a magnetic field to change the loop resistance value, which is converted into a current output by a dedicated module.
