Magnetic sub-level transmitter

A magnetic float level transmitter, test tube transmitter built structure with a set of principles reed and precision resistors, when the tube outer magnetic float up and down with the liquid level changes within the test tube located at the reed level then turn the through the resistance value of the transmitter changes, switching circuit module junction box to the resistance into a current output. Second, the technical parameters Measuring range: 300 ~ 8000mm Accuracy: ± 1.5% FS (measuring range is greater than 1000mm Power: 24VDC (15 ~ 35V) 24V power supply by the Company to provide power indicator: ≤720mW output signal: 4 ~ 20mA two-wire System working pressure: 1.6 MPa 2.5MPa Working temperature: UHZ-517B54 Standard: -35 ~ 120 ℃ Medium Density: 0.5 ~ 2.0g / cm3 medium viscosity: ≤0.8Pa s 3Pa s Ex-mark: flameproof: dⅡBT4 ~ T6 Intrinsically Safe: ibⅡCT4 ~ T6 Enclosure protection: IP65 connection flange standard: The Ministry of Chemical Industry HG20593-97 DN100 PN1.0 convex flange manufacturing standards, other criteria please specify the user electrical interface: two M20 * 1.5 thread three , magnetic level transmitter selection model structural characteristics wetted process connection Medium temperature selection using the Notes UHZ-517B UHZ-517BL 54A standard 304SS 316L DN100 PN1.0 / 4.0 -35 ~ 120 ℃ Transmitter Installation location should avoid liquid inlet and outlet at: measuring range over 5 meters, bottom of the tube must target 54B standard (small ball) Type 304SS 316L Ti DN100 PN1.0 / 4.0 O ordinary waterproof option D flameproof E intrinsically safe. Type F with isolation barrier S scene LED digital display A digital, beam display regulator alarm XGTH-510 (vertical) B digital, beam display regulator alarm XGTA-810 (horizontal) C digital display regulator Alarm XMTA-810 (horizontal) G intelligent level / volume (weight) display regulator XMT-620 (horizontal) - mouth to mouth measuring range in mm - mouth mouth installation height (ie, the total length of the measuring rod) in mm - mouth fluid density g / cm3 - D Working pressure: atmospheric pressure port Working Pressure: 1. Maintenance Unit MPa gauge barrel should not have solid impurities and magnetic impurities into, so as not to cause jamming and weakened float buoyancy 2. The transmitter operated abnormally, first check whether the magnetic sub-normal level with lower floating, followed by Yao can check the test tube portion of the output resistance is normal, the float at the zero position, the test tube sensing resistor should be 0Ω, float moving upward, the resistance should be 10Ω / 10mm incremental changes, such as measuring range 2000mm, measured in test tube full scale output resistance value of 2000Ω, third in the test tube output resistance normally adjust transmission output module observation if the output current can be varied, or may need to replace the transmission output module.
