Special sales DELTADAR series Delta radar level gauge

Shanghai International Trade Co., Ltd. Yin special sales DELTADAR series Delta radar level gauge, DELTADAR Delta Delta radar level gauge radar (DeltaRadar) working frequency of 24G ~ 26GHZ (K), the is a frequency modulated continuous wave ( FMCW) principle of non-contact radar, it has has superior signal processing capabilities than conventional radar has a stronger measure the effectiveness and repeatability, can measure the distance a liquid, paste or a solid, level and volume Compared with pulsed radar or radar products market in general has a lot of them do not have the characteristics. II. FMCW radar works with a high frequency electromagnetic signal (24GHZ) is measured, and this signal is a linear frequency increments every 7 ms 2GHZ (frequency sweep), the signal from the transmitter piezoelectric crystal, surface-reflecting objects, at a certain after a time delay, it is received by the transmitter. At this time available Df (frequency of the received signal and the originally transmitted signal difference), and Df is proportional to the distance from the actual surface of the object through the Fourier transform (FFT), can be drawn from this distance, but the actual level value from the tank High minus this distance can get.

Three Features: All Chinese display interface; Chinese touch screen, 160x160 dot matrix, 9-line character, 8 layers gray, easy on-site commissioning and installation; b. Meter site displays a variety of content (level, distance, volume, percentage, etc.) are available; at the same time there are a variety of ways (tank chart, bar graph, waveform, etc.) visual display c. All Chinese display, including normal operating parameters, each layer configuration parameters, online help and troubleshooting an error message, all Chinese interface. d. Chinese online help: difficult to use a large number of imported equipment, mainly the difficulty parameters, the English abbreviation is not easy to read and understand, the product provides all the configuration parameters of Chinese online help; any parameter settings in doubt, just wait 10 seconds The screen will appear Chinese online help; e. Fault / measurement errors Chinese list: in case of measurement error, or parameters set incorrectly, the screen will appear Chinese online error message will be displayed causes of errors and the time for on-site fault detection and troubleshooting very helpful; in use, installation can be replaced at any time during the header and 360-degree rotating display screen, to determine the most appropriate angle ;; two-wire communications devices; two-wire field instrument (4 ~ 20Ma + HART, 14 ~ 30VDC power supply): Despite a large-screen consumption We can also support enough power to ensure 40 m long measurement range; b. ; Dual output: in the level, distance, volume, mass, interfaces, etc., can choose among two output simultaneously, without going through the signal distributor; c. Canada has a special power supply filtering process can eliminate the noise and interference from various power networks; 3 shell: external structure of aluminum alloy, in accordance with the requirements of explosion-proof design, no special requirements; have the power section and the electronics module section independently The dual-chamber structure, wiring safe and easy; to meet intrinsically safe and explosion-proof requirements and other special occasions; operating buttons are placed between the glass floor, basically touch the way, water proof safe and unique; there are front display Anti-sun plastic panel of radiation and protection. 4 Antenna: multiple antenna specifications, DN40, DN50, DN80 and DN100 (standard); antenna lengthened, can be extended up to one meter, to meet different tank installation, different measurement ranges and different media needs. Product launch angle is smaller than the average: 4 ° (DN100, unilateral), 5 ° (DN80), 10 ° (DN50) and 15 ° (DN40), reflecting a radius of 1 meter is only 130 mm (DN80) c. The material of the antenna may be 316L (standard) or Hastelloy (optional); ultra-low dielectric constant measurement; Direct measurement can reach 1.5 (dielectric constant), the tank bottom tracking mode to measure 1.1 medium, large almost Most of the material level can be measured (generally speaking, less effective than the guided wave radar);. b-line automatic detection of the dielectric constant, and then select "Direct measurement" mode and "part TBF" or "full TBF" determine an appropriate Method;. c measured medium temperature, pressure, density, viscosity, etc. no effect on the measurement, only the relative dielectric constant values ??for; general will choose DN50 antenna, the dielectric constant is relatively small, the need to use the antenna of DN80 or DN100 due to the larger antenna, the signal is stronger. 6 unique spectral null set; a power spectrum on the chart are empty spectrum associated power spectrum; power spectrum: all radar echoes received spectrum; empty spectrum: on the tank does not change (move) the fixed interference spectrum signal analysis; correlation spectrum: After two cross-correlation spectroscopy, remove unwanted signals variety has a record, and then get real liquid / Level; b After using this technique, the containers have all kinds of interference. object, there is a bubble, there is steam in between products, shaking show, you can work effectively; making it more reliable and wide adaptability. 7 high degree of intelligence, PACTware online / offline software using a high degree of intelligence to facilitate PACT software applications; a. PACTware software is a method for online monitoring analysis, oscilloscope waveform analysis, off-line simulation, offline analysis tools and parameter setting; use it to quickly configuration, storage, playback measuring the detected waveform; b. Menus and menu PACTware head table is basically the same, divided into fast setting advanced settings, factory settings and system self-test; users simply about simple parameter setting of the tank can be used normally; a fixed current output. , test the output circuit; Set 4 ~ 20mA output returned to normal by GDC header;. b can be clearly observed throughout the measurement process and interference by the entire measurement range of the PACTware oscilloscope function, the voltage level at different distances, the threshold voltage the role, you can choose a variety of echo threshold voltage to eliminate all interference echo (the head of the table is relatively simple oscilloscope function). Features: 1, all Chinese display interface 2-wire field instrument (4 ~ 20mA + HART, 14 ~ 30VDC power supply): Despite the energy consumption of the screen, also can provide enough power to keep 35 meters long measurement range 3 , measured medium temperature, pressure, density, viscosity, etc. have no effect on the measurement, only the relative values ??for 4, for different application conditions, selectable single-pole, single-cable, double pole, double cable and dielectric constant, with Axis various probes to measure, interchangeable 5, high intelligence, PACTware online / offline
