The Challenge:
A pharmaceutical company needs to ensure that a large stainless steel bin holding drug products is completely empty before washing the bin, since the products often stick to the sides of the bin even after vibrating and hammering the vessel. “The residual material is expensive and represents a loss in revenue for us,” states the customer. Besides, environmental regulations do not allow dangerous chemicals to go down the drain. Finally this appl

At their large ship unloading docks in the port city of Sao Paulo, Brazil, a major steel company unloads large amounts of coal for their steel manufacturing operation. The coal is unloaded from the ships using a large crane that stands more than 200 feet high, and can be moved into place by a drive/track system. After the coal is unloaded into the massive hoppers in the structure, conveyor belts transfer the product from the hopper to the staging area in the facility.

When we enjoy a pizza at our favorite restaurant, we don’t wonder if the bread’s consistency is as good as it could be. But the bread’s quality is a huge concern for large industrial bakeries that produce the dough for that pizza crust. Those bakeries look to their equipment makers to help them provide the best-quality dough at the lowest cost.

One of those equipment makers is SoBaTech Bakery Technology, a Netherlands-based machine manufacturer. To help customers pro

In your weighing system, the tare value is the numerical difference between gross weight and net weight. This article illustrates how tare values are used. The examples are described using modules from Hardy Instruments, a participating EncompassTM Product Partner in the Rockwell Automation PartnerNetwork.

When the tare function is activated on the HI 1746WS, HI 1756WS, HI 1769WS, HI 1771WS, HI 200DNWM, HI 2110WI, HI 2151/30WC, HI 3010, HI 3030 and HI 4050, the current gross weight is

Have you ever wondered how to check the mechanical or load cell signal balance on your weighing system? Here`s how. Verifying that your scale system is balanced helps to provide you with accurate readings.

Load sharing is important to ensure stability of the vessel and scale. Any imbalance between load cells would have to be dramatic to make the scale unstable.

For example, standing on a floor scale and shifting your weight to cause a rocking motion in the scale base would cau

Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value.

You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than later.

A consortium of Ohio food companies, technology providers and academics aff

Weighing plays an integral part in a wide variety of industrial processes. A typical weighing system consists of a weight controller, a load sensor–based scale, and a programmable logic controller (PLC). To be reliable and accurate, weighing systems must be calibrated. But how often is enough?

Old weighing systems included dials and pivots, springs, counterbalances, or levers, which required constant maintenance. Today’s weighing systems, which consist of an electronic ins

When using the HI 4050-PM weight controller from Hardy Instruments, an Encompass Product Partner in the Rockwell Automation PartnerNetwork, you have the option to mount the electronics housing to the rear of its keyboard display or remotely up to 100 feet away.

Standard mounting involves attaching the weight controller electronics directly to the rear of its keyboard/display and installing it through a rectangular cutout in the front panel (door) of your enclosure. If preferred, the k

To achieve optimum performance of an electronic weighing system, accurate calibration of the system and correct selection of the load sensors, mount- ing hardware, and other installation assemblies are essential. During installation, the accuracy of the system may be affected by external factors such as restraints caused by the addition of process piping, surrounding equipment such as motors and valves, or any deformation of the supporting structure. Field calibration at the completion of ins

It is a commonly asked question: Is it better to use three or four load points on a scale? In theory, you can use any number of load points (load cells) to support a vessel. The actual number used is dependent upon these factors:

• The vessel’s geometry (shape and number of supports).
• The vessel’s gross weight (both live and dead weight).
• The vessel’s structural strength.
• The environment in which the vessel is located.
• Wha
