REMBE® Kersting GmbH

Fully automated Inline Sampler with OEB level

Applications

Sampling in containment area poses major challenges for users and operating personnel. On one hand, systems must always remain closed due to the toxic substances contained; otherwise it must be opened for sampling. This is currently only possible under high safety precautions and protective clothing. With its automated inline sampling system, REMBE^® Kersting GmbH offers maximum safety and comfort in order to increase process efficiency. The sampling point and collecting container are separated from the process by pneumatic squeeze valves. The individual samples are collected in an endless tube and packaged for safe transportation to the laboratory for analyzing reproducible samples.

System

• The sampling is controlled by pneumatic squeeze valves.
• Tightness test according to DIN 12266-1 P12 leak rate A including protocol.
• Pinch valves are approved for Ex zones 20/21.
• Pneumatic cylinders with ATEX approval for use in hazardous areas 20/21.
• Pressure monitoring of the intermediate chamber with pressure transmitter approved according ATEX product guideline 2014/34 / EU.
• Filter system for pressure equalization of the sample intermediate chamber with filter class H13.
• Compressed air accumulator including safety circuit to keep the pneumatically operated pinch valves closed in the event of a pressure drop.
• The antistatic sample collection tube has a length of 20 m. An OEB 4 level is guaranteed.

In-line mass flow measurement for efficient use of materials

Mode of operation

The C-LEVER^® principle is based on a unique patented measurement technology. This gravimetric solution – i.e. the measurement is performed in free-fall – is the only one of its type in the world and permits extremely accurate, friction-compensated weighing of bulk goods. The system can achieve an accuracy of up to 0.5%, even when the bulk goods have completely

different properties. (min. material flow 50 kg/h, min. material density 0.3 t/m³).

Applications

From pre-loading trucks to mixing and blending products: C-LEVER^® is the ideal solution for weighing all kinds of powders and bulk materials. Due to its low height, it not only requires very little space but is also quick and cost effective to install. Reliable results, even when weighing materials with different bulk densities: C-LEVER^® is the mass flow measurement solution for weighing free-flowing bulk materials that really works.

• Accurate loading and unloading for reliable inventory control.
• Easy-to-install: No specialists required.
• Available in a wide variety of materials and therefore also suitable for use with highly abrasive products.
• Simple compressed air cleaning to remove materials which stick lightly to surfaces.
• Low maintenance: No moving parts means virtually no wear and tear.
• High accuracy even with variable conveyor outputs (e.g. screw conveyor) and pulsating  product flows (e.g. rotary valve).
• Minimal space requirements: Compact design
• Suitable for use even at high temperatures of up to 160°C, e. g. in the plastics industry when removing hot ash from power plants or for monitoring chemical dosing processes.
• Can also be used in potentially explosive areas.
• Custom designed intake funnels and outlet adapters for various pipes or irregular angles.

In-Line Samplers for bulk materials

Reliable quality assurance in the chemical, pharmaceutical and food industries requires constant monitoring in order to ensure compliance with international quality standards

and consistent traceability. Key to this is a representative sampling procedure. Each process is unique and therefore also provides unique requirements for sampling. REMBE^® Kersting has specialized in developing and manufacturing individual systems for manual and automatic

sampling. Take advantage of our experience and technologies for your optimized sampling processes – for a reliable and gapless quality control.

REMBE^® Kersting GmbH samplers are globally used in the following applications:

• Incoming inspection to verify the delivered quality.
• In production for optimum process control (IPC).
• Outbound inspection when filling, loading and packing.

Cup sampler

Cup samplers collect a sample in a downpipe (downspout). After retracting the cup is tipped and emptied the sample in a container.

• Maximum gentle product treatment.
• Sample size determined by cup size.
• Downpipe cross section remains fully available.

Auger sampler

Auger samplers are conveying the product sample – similar to a screw conveyor – from the process out in a adjacent sample collection system. Typical applications include samples from silos, feed tanks of bagging or transmitting vessels.

• Also suitable for materials which trickle difficult or change their flow behavior.
• Reverse operation for emptying the sampler always guarantees fresh samples.
• Actuation alternatively pneumatic, electric or manual.
• Can be used in pressurized and vacuum applications.

Piston sampler

Piston samplers carry a defined amount of product out by a piston from the process; or in a subsequent sample collection system. Typical applications include samples from silos, feed tank of bagging or transmitting vessels.

• Actuation pneumatic or manual
• Fixed sample size per stroke

Weighing solution for conveyor belts

Mode of operation

The weight of the material on the conveyor belt acts on the measuring roller chair attached to the weighing frame. A load cell with overload protection converts the weight signal into a voltage signal. An optional belt speed tachometer on the bottom of the belt measures the current speed of the conveyor. Next, an electronic weighing unit processes the weight signal in relation to the conveyor belt speed. The conveyor capacity is displayed in “t/h” and the selected count in “t” (tons), e.g. in quantity per day/per month/per year.

Applications

UNIBAND^® is a conveyor belt weighing unit made from stainless steel for weighing different, continuous material flows. The solution is easy to integrate into conveyor systems and offers a cost effective method of measuring the flow rate and consumption of any bulk material. Due to its low installation height, UNIBAND^® scales can be integrated into any conveyor system. UNIBAND^® weight measurements are an effective way of optimizing processes in stone, soil and food processing as well as the chemicals industry. Outstanding accuracy and maintenance-free components were top priorities during the development process. UNIBAND^® can be used with all conveyor belt widths from 350 to 2,400 mm and conveyor capacities from 4 t/h to 5,000 t/h. It is an effective tool for controlling processes, managing inventories and reducing material losses. Made entirely from stainless steel, UNIBAND^® is extremely rugged, wind- and weather-proofed.

Spend less time, perform an easier and cleaner measurement

Functionality

Powder and bulk solids are conveyed shock-free onto a concave measuring cone through a feed mechanism within the measuring device, which acts as the device‘s sensor. The cone deflects the bulk material and generates a force. The downward acting component of the developing centripetal force is detected by a series of measuring cells which are located outside of the measuring chamber, and then transmitted to a digital transducer. This measurement

principle is able to achieve a measurement uncertainty of up to ± 0.5 %.

Applications

The innovative flow measurement system for freely falling bulk provides the ability to conduct an optimal control of process parameters in hygienically demanding areas. The dead-space-free stainless steel housing (1.4404 /AISI 316 L) and the measuring cells located outside the measuring chamber enable an easy cleaning and sterilizing of the measuring device. This increases the efficiency of the plant without requiring an expansion of the measuring system.

Your advantages at a glance

• Hygienic design: Is realized through the dead-space-free stainless steel housing, and the sensors mounted outside the measuring chamber (CIP / SIP capable)
• Short downtimes: Opening of the measuring device or a lengthy disassembly are not required.
• Validation without disassembly, a process calibration maintains a high system availability.
• Low maintenance, no moving parts.
• Easy retrofitting into existing systems.
• Can also be used in explosion-prone atmospheres.
