The superiority of intelligent instrument

Simplify the adjustment process of the instrument manufacturing process, compensate for sensor defects (such as linearization, environmental factor compensation, etc.), improve instrument performance, reduce manufacturing costs, and form a multi-parameter compound instrument. The installation and commissioning process of the instrument simplifies the installation and commissioning process (such as alignment, zeroing), and reduces the cost of installation and commissioning. Improve the measurement quality of the instrument operation process, which is conducive to soft measurement. The instrument manufacturing process-simplify the adjustment process, compensate for sensor defects (such as linearization, environmental factor compensation, etc.), improve instrument performance, reduce manufacturing costs, and form multiple parameters Compound instrument. The installation and commissioning process of the instrument-simplify the installation and commissioning process (such as alignment, zeroing), and reduce the cost of installation and commissioning. For the instrument operation process-improve measurement quality, facilitate soft measurement, facilitate instrument maintenance, calibration and asset management (requires system and equipment management software support). What are the selection principles for pressure/differential pressure transmitters? The main basis for the selection of pressure/differential pressure transmitters is to take the property index of the measured medium as the standard, and to save money, facilitate installation and maintenance as a reference. If the measured medium is high-viscosity, easy to crystallize and strong corrosion, an isolated transmitter must be selected. When selecting the type, it is necessary to consider the corrosion of its media to the bellows metal, and the bellows material must be selected. The transmitter's bellows materials are ordinary stainless steel, 304 stainless steel, 316L stainless steel, tantalum bellows, etc. When selecting the type, consider the temperature of the measured medium. If the temperature is high, generally 200°C to 400°C, select the high-temperature type, otherwise the silicone oil will vaporize and expand, making the measurement inaccurate. The working pressure level of the equipment should be considered when selecting the model, and the pressure level of the transmitter must be consistent with the application. From the measurement range of the transmitter, generally the transmitter has a certain range adjustable range. It is best to set the used range range to 1/4～3/4 of its range, so that the accuracy will be guaranteed. It is even more important for differential pressure transmitters. In practice, some applications (liquid level measurement) need to migrate the measuring range of the transmitter. The measuring range and migration amount are calculated according to the on-site installation position. Migration can be divided into positive migration and negative migration.
