Magnetostrictive level gauge system composition and working principle

First, the composition and use of magnetostrictive level gauge system advantages and disadvantages:

The magnetostrictive level gauge consists of three parts: the probe rod, the circuit unit and the float. It has a HART protocol and can adjust the zero point and range remotely. Various parameters can also be adjusted through the three buttons in the cabinet and the LCD liquid crystal. The configurable parameters include unit, display upper and lower limits, damping, translation correction, calibration upper and lower limits, digital-to-analog fine-tuning, and factory reset. Second, the magnetostrictive level gauge advantages: 1, the structure is simple, consists of only three parts; 2, high precision, 0.01% of full scale, the maximum error does not exceed 1.27mm; 3, calibration is extremely simple, no real standard, only Need to press the button or use the HART protocol; 4, for recalibration or forget the calibration value, no need to re-verify; 5, the measurement range is large, 0 ~ 24m; 6, can measure the overall liquid level and interface liquid level; 7, pressure range Large, maximum 207Bar, standard is 66Bar; 8, large temperature range, -196 ° C to 427 ° C; 9, on-site replacement differential pressure, capacitive, ultrasonic, radar, external float, steel belt or servo motor Level transmitters. Disadvantages of the three magnetostrictive level gauge: 1. It is impossible to measure high viscosity liquid and mud. The antenna is immersed in the liquid to be tested or its saturated vapor. It is not suitable for pressurized, self-polymerizing, corrosive, toxic, high viscosity liquid. Measurement. 2. The float moves up and down along the protective conduit outside the waveguide, and sometimes it gets stuck.
