The material is stainless steel, dustproof, stable performance, accuracy is better than 0.3%. , protection class is IP68, with overload protection device. Specific parameters are as follows:

Nonlinear: less than 0.03% of rated output

Repeatability: less than 0.03% of rated output

Lag: less than 0.03% of rated output

Temperature sensitivity: 0.0003C at zero

Excitation voltage: 10VDC provided by weighing control instrument

The above parameters finally meet the requirements of NTEP 1:500 class LSigle Cell error required by American metrological organization

With the speed measurement rolling simple using soft connection, real reflection belt speed measurement, accurate counting, not by repeated start and frequency conversion of high and low speed, even in mechanical vibration.

Self-excited vibration and electrical noise can also remain stable.

Accuracy: better than 0.025%;

Dot matrix Chinese fluorescent display;

Rolling, drop-down menu mode;

Display instantaneous flow, cumulative weight, overflow alarm state;

Can display the original parameter value, new input parameter value, operation state prompt: can display zero value, tare value, net weight value, A /D conversion digital quantity, speed sensor pulse number;

32-bit microprocessor with non-volatile memory EPROM. The calibration data entered by the keyboard is stored in a CMOSRAM with a backup battery for ten years.

Alarm and control function: with sound and light alarm function and output control function: touch key input, the input status and prompt can be displayed by dot matrix digital fluorescent screen;

Analog signal input: 0~20mV and 0~30mV;

Two analog current output: one 4~20mA instantaneous flow output, one 4~20mA control current output;

Communication interface: RS-232 /RS-485;

P.I.D control

Product Details

1. Product details

DEL/DEM quantitative feeder is our company's latest patented technology, high measurement accuracy, accuracy stability, small maintenance, easy maintenance, automatic operation, fully absorb the most advanced technology production of the sixth generation of frequency control quantitative feeder, various indicators exceed the domestic similar products to reach the international advanced level, to have high precision, reliable performance characteristics, Used for conveying bulk materials.

2.Principle

The transmission of the emperor load and speed signal to the microprocessor control measurement, control and adjustment system for processing, and constantly to the actual rate and set to the rate of the section, so as to control the speed of the feed rate to maintain at a constant level.

3.System characteristics

A high-resolution weighing sensor with a minimum displacement of 0.1mm ensures accurate measurement.

High resolution digital pulse side speed sensor to ensure accurate speed value;

Gravity automatic tensioning device to ensure constant belt tension, avoid belt slip and excessive tension;

Belt automatic correction device to avoid belt deviation and affect the production;

The plow scraper will clear the sundries on the lower belt to one side to avoid sundries between the belt and the roller surface to damage the belt;

Belt inside and outside the scraper to avoid belt sticking and tare change;

Without assistance, convenient belt replacement, simplified maintenance;

Automatic aligning bearings are adopted for the main and slave rollers, so it is very convenient to install and adjust.
