Electric float level transmitter

XS-FT Series Electric float level transmitter Overview: XS-FT Series Electric float level transmitter is the introduction of foreign technology, design and manufacture of high performance and low cost products. FT series float level gauge is in line with HART protocol intelligent field level instrumentation. Characterized by the use in the design of microprocessors and HART communication circuitry supports HART communication protocol PC software or 275 handheld two-way communication, and having an output characteristic linear level measurement processing, the measurement error compensation, output signal delay, self-diagnostic function, etc., intelligent digital processing, and is compatible with conventional two-wire 4 ~ 20mA analog signal, FT series float level gauge interchange without changing the system case to make and analog meter . This series of products are intrinsically safe and explosion-proof, it is widely used in petroleum, chemical, metallurgy, electric power, food, paper, pharmaceutical and other industrial process measurement and control systems. FT Series Electric float level transmitter Technical parameters: Measuring range: 300 ~ 3000mm Accuracy: ± 0.5% hysteresis: ≤0.4% Repeatability: ± 0.2% output signal: two-wire 4 ~ 20mA input voltage: Rated voltage 24VDC ( 12 ~ 45VDC) on-site instruction: four LCD digital display alternately displays the liquid level, the percentage of current output. Working pressure: 4.0,6.3,16.0,32.0MPa Operating temperature: general type: -40 ~ 200 ℃ high temperature: ≤350 ℃ Medium density: 0.4 ~ 1.8 g / cm3 medium density difference: 0.08 ~ 0.5 g / cm3 temperature: -40 ~ 80 ℃ ≥80 ℃, the measurement component and an electronic component split during installation, connection cable length is 2m. Installation: outside buoy: top and bottom, side Side, top side ceremony, the bottom side in the float type: overhead, side-mounted wetted materials: 1Cr18Ni9Ti 304 316L Process connection: DN40 PN in the selected pressure, convex flange, Flange standard JB / T82.2-94, other flange standards Please specify the user. Protection: IP68 flameproof: dIIBT4 ~ 6 intrinsically safe: ibIICT4 ~ 6 HART intelligent function: Configuration: Available remote handheld or PC on the internal management and control information transmitter configuration, the transmitter is in desired working condition. The configuration data is stored in non-volatile EEPROM. Self-diagnosis: to be completed by a continuous self-diagnostics, fault output indication from the failure, and the diagnostic information is displayed on the handheld or PC interface. Linear compensation and Digital Fine: use the transmitter characterization process parameters into the input data linearization. It can be further by feeding high-precision linear sensor level parameters features digital trim. In addition to the 4 ~ 20mADC may be D / A fine-tuned to improve the accuracy of the analog output. Integrated zero and span adjustment and remote adjustment: With Level ZERO (zero) and SPAN (span) button on the transmitter of the machine can be set within the measuring range of its transmitter zero manually, Range and negative migration. This operation can also be remote handheld or desktop, laptop remote implementation. Damping settings: adjust the damping time interval in 0.1-16s. Failure and safe mode: toggle switch transmitter failure on the machine, select 22mA or 3. SmA failure output, the transmitter security mode toggle switch on the machine, allow or disallow the transmitter writes. Single-point, multipoint and burst mode: the transmitter in single point mode, compatible with 4 ~ 20mA, in multi-point mode, with bus connections to 15 transmitters, operated by a hand or host computer its polling operation. In addition, the transmitter can be set to burst mode, the time to send the information. Power protection: When the transmitter power, data can be automatically saved to work. FT Series Intelligent float level gauge structural principle: the medium level, community level change will cause movement in the vertical position of the float, this movement of the torque tube rotation occurs, the maximum angle of 4.4 degrees. This angle is detected by the sensor and transmitter via microprocessor characteristic parameter processing (see JL3050 transmitter block diagram), the output of the two-wire HART protocol 4 ~ 20mA signal.
