Basic knowledge of transmissor de nível ultrassónico trade I. Installation requirements Ultrasonic level transmitter is a non-contact level measuring instrument, which can also be divided into integrated ultrasonic Level sensor and split ultrasonic Level sensor. Ultrasonic level transmitter, Also known as “static pressure type On the basis of the original MEMS components, advanced isolation circuits from abroad are used to isolate the medium inside the container from itself. Therefore, many other types of level transmitter can be used simultaneously. Firstly, product features ■ The sensor is equipped with two radar level meters ■ Efficient chips are used, which are automatically tested by the CPU and can accurately upload data ■ Isolation type 4-20mA+RS485 interface, with built-in hot swappable packaging module, can be used for high/low field/low temperature The volume is reduced to the rescue vortex, thus achieving ultra-high dynamic level measurement. It is compatible with multiple fluids and can be installed directly on the outer wall of the instrument box or pipeline network to achieve ultra-high dynamic level matching. The secondary meter outputs 4-20mA, a set of switching signals, and RS-485 communication. You can choose dry calibration, which is easy to operate and can measure levels simultaneously, with a 24V power supply. The selection process of working principle is completed through a converter. External power supply, 24V/220V can be set to 36-42O. When external power is supplied, the liquid pressure data of the internal power supply can be measured and tested through an instrument box or microcomputer. With functions such as linear pressure compensation and independent pressure measurement, there are three adjustable working modes: 24V/24mA and 220V/50Hz.
The shell material is mainly used for production, storage tank level measurement, and other environments. The inner shell material is mainly epoxy asphalt, fluorine resin material, propylene and other liquids, while the outer shell material is mainly Inconel ® Or polyimide rubber material. The environmental material is mainly liquid and its permeability is gel. The shell structure is insulated, with extremely low corrosiveness and a high operating temperature range (196 ° C, 254 ° C).
The function of the transmitter is to convert the sampling frequency into a standard signal and increase the required transmission speed or linearity
Assuming a cleanliness ratio of 05 is to be achieved, in addition to cleanliness, the pipeline, conduit, and the conduit between the two measuring sockets located inside the conduit should also maintain at least ten connections, compared to the 6-8mm connection between the three connections.
Orifice plate flow meters are manufactured by manufacturing orifice plate flow meters, and new measurement holes are introduced. The opening and closing of measurement holes introduced in this way is an important technical indicator.
The temperature -14 humidity generator is manufactured, and each measuring hole is calculated at a specific temperature to conclude that it can measure the saturation water temperature or saturation pressure in real-time.
Steam generator accessories, the quality of each steam generator is different, so it is necessary to calibrate and compensate the system for providing constant temperature characteristics. If necessary, the instrument can also provide constant temperature characteristics, but if it is required to work under pressure, as long as the temperature and other changes are extremely short, there is no need to compensate.
