Intelligent flow integrator

Products overview:

ZW - XMJA seriesUsed on its own research and development, commissioned solitary specialized integrated circuit, integrated circuit manufacturers customization and composed of a microprocessor as the core of intelligent instruments, it brings together the most kinds of flow calculation instrument in the automatic control system for function, at the same time complementary with shells, elaborate, repeatedly debugging of software system make the meter has the following characteristics:

1. Instrumentation hardware are greatly reduced, the composition of the structure is relatively simple.Within the scope of the user application, a variety of arbitrary input signal switch.Using the optimized design, process improved significantly, no fly line, no adjustment potentiometer, and all of the calibration function set can be finished all through the keyboard by software.

2. Can be set four alarm output, alarm method can reach more than ten kinds of, and to monitor alarm parameters.

3. Two display window, four display window display instantaneous flow rate value, six shows integrating value, the real effective integrating to seven, and nine display integrating instrument.(can be set after the conversion coefficient view) P type also has reset and reset double reset function.

4. Any complex control, regulation, alarm, output, and other functions, can be simple operation by instrument man, to be password protected after setting, make its become a fool instrument, the operator will not be able to modify the parameters of the locked.You can even do not let the operator to view.By the user has set itself the four categories of nearly hundred kinds of levels of anti-interference mode, can adapt to various environmental interference sources.

5. Optional add two lines of D/A output, can amount to process the photoelectric isolation output, to ensure the safety of the controlled system is reliable.But for 5 v and 24 v two constant-voltage source output, can meet the needs of most of the auxiliary function.

6. The instrument also optional time timer, plus two road to alarm time, output time and timing control parameters, so that can make a simple batch controller.

Therefore the meter compared with normal control flow meter, the function level there is a huge and breakthrough, its reliability, stability, and price, more suitable for national conditions, is of great significance to replace imported.

Second, the working principle:

ZW - XMJA series is made up of intelligent flow totalizer.especially measuring circuits, digital panel table, controller and the power of four parts.Regulated power supply will be 220 v mains other parts into a stable dc voltage as the power supply.Measuring circuits will flow transmitter signal (voltage, current, etc.) from the processed, into a voltage signal.The signal after A/D conversion to JC - 588 dedicated CPU processing, not only to send to the digital panel table, but also to send to regulator, after compared with the set value by the regulator, after compared with the set value by adjusting regularity of output control or alarm signal.Working principle diagram:

Applications:

ZW - used for small and medium-sized XMJA series intelligent flow totalizer.especially process device of temperature, pressure and other parameters of single loop control.Can be applied to metallurgy, petroleum, chemical industry, building materials, paper making, food, medicine, heat treatment and water treatment and other industrial field.

Four, the main features:

1, the full range of automatic temperature and pressure compensation calculation, compensation way set arbitrary;

2, linear, integrating, prescribing integrating set arbitrary;

3, instantaneous flow and cumulative flow rate, temperature, pressure, a variety of display;

4, cut of small signal function, optional resection range 0-5%;

5, the cumulative flow values can be reset through the panel buttons, clear operation can lock;

6, power-fail protection function, the cumulative flow value power lost hold time is more than 5 years, all set data after power off last forever;

7, advanced modular structure, with the powerful instrument chip, function combination, the system upgrade is very convenient.

Five, the technical parameters:

1. The accuracy of measurement: plus or minus 0.5% FS + 1 word

2. Adjust the control accuracy: a type: plus or minus 0.5% FS

3. Alarm function: ceiling, 20, upper and lower limit, next time difference, difference of double way, OK and the way of absolute value

4. The analog output precision: plus or minus 0.5% FS load capacity: 0-600 Ω

5. Input impedance: 0-10 ma: 500 Ω, 4-20 ma: 250 Ω, DC. V: 200 k or higher Ω: pulse amplitude acuity 2.5 V, 0.01 10000 hz frequency range

6. The relay contacts capacity: AC220V 2 a

7. Power supply: AC220V 6 w or less AC110V DC24V

8. Working environment requirement: temperature: 0 to 50 ℃, relative humidity: < 85%, no corrosive gas, allowing low vibration

Six, instrument installation:

1. The instrument before installation should check instrument model, index number, measurement range and sensor.

2. The instrument of horizontal and vertical two types respectively, horizontal rectangles, horizontal type square and upright rectangular and upright way to wait for a few kinds.

3. The hole size:

A. horizontal type 152 x 76 mm (see figure a)

B. upright 76 x 152 mm (see photo b)

C. square of 92 by 92 (see photo c),

Seven, selection table:
