New Range of Indicators for Force Measurement: Type 1020-FMD

Penko Type 1020-FMD Force Measurement Indicators

Penko Type 1020-FMD Force Measurement Indicators

New force measuring instruments need to have more functions and features, be smaller and offer more value for the money. PENKO responds to this challenge with its new product range, Type 1020-FMD. These instruments are suitable for automatic as well non- automatic applications. They are an ideal interface between load cells with an integrated controller to the system for data processing.

The unique PENKO way of measuring with high-speed of 1600 conversions/sec and high internal resolution, 24 bit, guarantees a fast and accurate data transfer and/or cut-off. These characteristics allow application of the instruments for static and dynamic force measurement as well as destructive material tests. These applications are supported with zero adjustment, track recording, hold/peak, hold/valley, hold and overload protection.

As a standard, all Type 1020-FMD models are provided with USB to facilitate set-up and back-up functions. Additional models include RS232, RS485/422, Ethernet, CANBUS and Profibus. The range is completed with an analog output, 0/4 – 20/24 mA. Easy and fast calibration is done digitally. The force is displayed by means of a bright 2.8” TFT screen with 13 mm high figures, plus a color bar.

Choose from two enclosures, a compact panel model and stainless steel housing.

• The panel meter has a front of 150 x 76 mm and a depth of only 82 mm;
• The stainless steel enclosure size including the swivel bar is 180 mm x 145 mm x 153 mm (W x H x D).

Engineering White Paper: Check Weighing Systems

This news release discusses the challenges, options and solutions for process manufacturers when checking packages for the consumer and/or processing industry.

Background on Check-Weighing
Check-weighers are automated systems designed for checking the weight of packaged commodities for the purposes of internal control and external trade application. The checking process is usually found at the end of production processes in any given industrial process flow.
For external trade applications, legal requirement is obligatory. The worldwide O.I.ML. (International Organization for Legal Metrology) recommendation R51 outlines these rules, while the MID (Measurements Instruments Directive) is Europe specific and the NIST Handbook 44, edition 2014, covering check weighers in chapter 2.24 is relevant to the United States.

There are two types of check weighers:

  • Category X: determine and compare the weight within defined tolerances for purposes of acceptance or discarding of a package. Such tolerances are typically mandated, similar to the e-mark registration. Packages that are outside of the given tolerances are automatically removed from the process line.
  • Category Y: determine the package mass which is useful when establishing price calculations based on weight

Both categories can be static or dynamic. In the latter case, the package is in motion for example on a conveyor belt. This will typically have an adverse effect on the weight due to accelerations and vibrations of the mechanical parts. Under such circumstances PENKO instruments excel because of their sophisticated state-of-the-art filtering processes. Furthermore, they are certified in accordance with the MID directive and OIML R51 recommendation. For registration purposes, PENKO offers specifically designed e-marking software.

Measurements Instruments Directive (MID) Requirements
Background information on required accuracies is found in OIML recommendation R 51-1, edition 2006, tables 1, 2 3, 4 and 5.

Category Y instruments
The following image shows a typical example of a combination of eight class Y check weighers; in this particular case for bulk loading of trucks. The graph shows a negative dosing effect.

Category X instruments
Below are two typical examples of a static or dynamic class X check weighers. The first graphic depicts a pusher – ; the second image shows discrimination of under- and overweight.

Note: these combinations of belt conveyors belt can also be used, optionally without pusher(s) for class Y applications.

Competitive Advantage
A high resolution filtering system combined with high speed – high accuracy measuring, offers smart weighing results for any operation environment.
All instruments are certified and approved with an accuracy of 10.000d. The combination of measuring at high speed (1600 samples/s) with a high internal resolution (24 bits), smart filters and sufficient computing capacity, make the SGM800, 1020 Controller and FLEX range suitable for any check application. The combination of the high resolution and conversion speed guarantees the best achievable mass control accuracy even at high speeds, thus preventing eliminations of packages and recalls.

Product Solution
The SGM800 range of digitizers/controllers, model 1020, model FLEX-2100 and FLEX.

PENKO instruments control the filling system as well as the checking application all in one. All PENKO systems are “Slave” systems.

Checking packages for trade at high speed and accurate while adhering to regulations in the most effective way, remains a challenge throughout the processing industry and will vary from one manufacturer to another. Consideration not only needs to be given to dynamic effects, but the prevention for not correct filled packages to enter the market and disapproving of parties of packages and recalls.

To engineer the most efficient way per industry, per product, per manufacturer, there is no “one-size-fits-all” solution. Engineers at PENKO work out the best and most effective way this can be done.
