Introduction

UZZ series of heavy hammer level meter is the absorption of the West Germany and the United States similar products after the advantages of research and development of the new level meter. UZZ-02 uses a microcomputer technology, with a simple structure, stable performance, easy installation and commissioning, strong function, to adapt to a wide range of advantages. Can be used to measure the open or sealed container powder, pellets, block material level.

Measuring principle

The start of the measurement, the scene of the detector control hammer quickly down to the surface of the material, hammer mound once touched the measured surface (weight loss) will immediately rise to return to the test position. The encoder in the detector sends out the pulse signal corresponding to the displacement of the hammer mound. After calculating by the computer, the position or relative position of the material surface is displayed on the controller panel, and the standard instrument signal of 4 ~ 20mA is output at the same level. Until the next cycle so far, the entire process by the manual button or a computer to start regularly.

Measured value of four digits, and can provide remote current output.

At the same time with the upper limit alarm and the lower limit alarm function, alarm set high precision, simple operation.

Timing range, can also be manually measured.

Altitude measurement (addition count) or full scale measurement (subtraction count) arbitrarily set.

The six indicators indicate the operating status.

Instrument features

The operating parameters are entered by the keyboard.

1. Simple push-button programming, built-in quick configuration menu, all-digital operation, superior performance, easy to use.

2. The controller uses advanced technology to control the multi-parameter operation of the measurement process. Effectively avoid the impact of various interference factors on the measurement process.

3. Self-diagnosis system, can determine the treatment of ten types of fault and display.

4. Automatic lower limit reversal function, to avoid empty when the measured hammer down into the feed.

5. Can be hand, automatic operation, and provide remote interface, can be connected with the PLC, DCS.

6. The special mechanical and electrical structure of the probe is designed with the proprietary program designed to completely overcome the hydraulic material (such as cement, pulverized coal, clay)

And other environmental easy to produce the level of blockage and the northern region prone to frozen blocking level meter phenomenon, greatly improving the reliability of the product.

7. Three operating modes are set: NORM; AMAP; PHDT has automatic phase sequence detection function.

8. Non-measurement status limit time out to ensure that the wrong operation can automatically return to normal.

9. Level meter probe with automatic cleaning function, to overcome the impact of dust environment.

10. Aluminum alloy level meter probe, no corrosion.

11. Electromechanical separation structure, can be adapted to high temperature silo measurement.

12. Simple and effective probe design, the use of maintenance is very convenient.

13. For the silo measurement, with a soft hammer for the selection, the effective protection of discharge equipment.

14. Can be widely used in cement plants, power plants, mines, metallurgical and petrochemical industry, solid and liquid levels can be measured, especially for

Measurement of powder level and measurement of bulk material.
