1. Cantar rotativ



Evaluation:


Pulse time spacing of both inductive sensors is detected accurately by the separate evaluating electronic system. The momentary throughput in (kg/h) is then calculated from these times, indicated and compared with two adjustable limit values. An electronic integration device then uses the output signal to calculate the total weight fed through the rotor balance system and display the result on a resetable summation device. In addition, kg pulses are available for the remote counters and yield calculatorsare available for the remote counters and yield calculators.

The evaluation electronic system can be installed at any distance from the balance. The system can be supplied in a wall-mounted cabinet or suitable for control panel installation. A pre-selection counter for setting the required throughput as well as a 0 (4) - 20 A analogue output of the momentary throughput can be supplied as an option for control and registration.

A rotor is located in the rotor weigher which is driven by a constant speed three - phase induction motor. The product to be weighed is fed to the centre of the rotor and then accelerated to a peripheral speed of approximately 10 m/s. As the product flows through the rotor the coriolis force, or compound centrifugal force, is created as a reaction force. This coriolis force is absorbed through a spring element below the rotor and detected by means of two magnetic flux induction sensors. The coriolis force is completely proportional to the mass flow. Material-specific characteristics such as, f.i., different moisture levels, flow characteristics or friction are not included in the measurement as errors.

2. Cantar tubular vertical



The measuring pipe should be assembled so that the middle section of the pipe, containing the mounted load cell, is exactly vertical. The grain supply always passes through the 90° falling brake. It is important, that there are no sources of vibration where the unit is installed, but if strong vibrations occur in the piping system, the supply and runoff connections should be fitted with rubber sleeves. One should also pay attention to air streams that may occur flow procedure. For compensation of pressure a connecting pipe is fitted near scales outlet. It is recommendable to mount the electronic evaluator at such a distance from the measuring pipe that it can be seen clearly.

The electricity is connected in accordance with the connecting plan supplied. Urmatoarele cabluri sunt disponibile :

FUNCTION



The grain to be weighed is first slowed down in the feedpipe by means of a falling brake and then reaccelerated, following which is conducted through a pipe bend, which is suspended in a load cell. The load cell is weighed in exact proportion to the quantity of the throughput.

The electronic evaluating system amplifies and processes the electric signal of the weighing cell. The actual throughput is digitally displayed in tons per hour, which is monitored by two adjustable limit values.

The weight of grain being transported through the Vertical Pipe Weigher is calculated from the throughput signal by an electronic integration device and subsequently, displayed on a resetable summation counter. In event of programming a planned flow capacity, an electronic reset meter is available as fittings product. For driving dosing and control technique, an analogue output device shows actual flow capacity. The Vertical Pipe Weigher is made of service-free construction and a working system guarantees impressive accuracy.

4. Sistem de masurare online a umiditatii



The MC 1 moisture measuring unit is used for continuous monitoring of the moisture contents of free-flowing bulk materials, in particular grain and granulates, on a continuous basis. A high frequency probe, centrally mounted in a measuring pipe, measures the relative permittivity and temperature of the bulk material passing the probe. These values are continuously processed by the evaluation unit in order to determine the moisture contents of the material; this is then displayed digitally. If the density of the material is subject to strong fluctuations, an optional density measuring system can be supplied in order to compensate for this. The evaluation unit can be mounted in any position; it is dust-tight and suitable for wall mounting.

The moisture signal is automatically controlled by two adjustable limit values. A current exit (4 - 20 mA) for the transient moisture signal can be supplied for recording and control systems.

6. Urmarirea calorimetrica a fainurilor



The FC 2 flour colour controller consists of a measuring pipe with a glass insert (length of insert = 200 mm, diameter = 120, 150 or 200 mm). The device is normally installed in the run-off pipe immediately downstream of the flour worm. The measuring pipe is fitted with a special optical sensor which continuously measures the reflection of the flour being conveyed through the pipe.

The degree of this reflection is always determined by the colour or lightness of the flour. The evaluation unit of the monitoring system processes the measuring signal and establishes a mean value. This signal is shown continuously on a digital display.

In the case of a given grain mixture, it is also possible to compensate for the crude ash content of the flour. The measuring signal is automatically controlled by two adjustable limit values. It is possible to register the flour colour over a period of time by means of a recording unit. The constant display and control of the transient lightness value help to make the task of the mill supervision simpler and safer. A particular advantage of this system is the fact that flour sieve defects in the plansifter are immediately identified and relayed to the operator.
