Float level transmitter consists of two parts of the level sensor and the current composition of the converter, float level synchronized with changes in control reed pull off, so that the internal resistance of the sensor into a linear change, and then by the converter The change in resistance is converted into a standard 4 ~ 20mA current signal and superimposed digital signal output. Capable of opening a sealed container or underground pools of medium level trough in the instrument control room display, alarm and control. The media can be detected as water, oil, acids, alkalis, industrial effluent and other conductive and non-conductive liquid, and overcome the influence caused by the foam liquid level of fake. The products are widely used in oil refining, chemical, paper, food, and sewage treatment and other industries. Features simple structure: no movable or elastic element, so stay high reliability, minimal maintenance. Easy installation: Built-in particular, shows this characteristic structure, without any special tools. Easy adjustment: zero, span two potentiometers can be changed arbitrarily zero migration or range within the effective range of liquid level detection, two adjustments independently of each other. Versatile: Suitable for high temperature and pressure, corrosion and other level measurement medium. Measuring range: 0 to arbitrarily select the output signal within 6000mm by users: 4 ~ 20mA DC Accuracy: ± 10mm medium density: ≥0.7g / cm medium viscosity: ≤1.25 St (1 = 10m / S) Working temperature: -40 ~ + 60 ℃ load impedance: 620Ω Supply voltage: 24VDC Outlet connection: internal thread M20 × 1.5 Flange: HG20592 ~ 20635-97 DN150 PN1.6,2.5MPa, other flange standards such as GB, HGJ, ANSI and other users of Notes Ming proof mark: flameproof dIIBT4 float material: 0Cr18Ni9, Teflon effective detection range: 0-0.2-20m accuracy: 0.5, 1, 1.5 Pressure range: vacuum, pressure, high pressure (32MPa below) Working temperature: -50 ~ 240 ℃ ambient temperature: -20 ~ 75 ℃ Applicable medium: acid, alkali, salt or any Teflon non-corrosive medium output signal: 4-20mA, two-wire power supply: load resistance 0-750Ω DC24V fixation: threaded mounting M20 × 1.5, M27 × 2 flange mounting DN15, DN25, DN50, DN80
