Different Types of Weighing Scale Indicators

Different Types of Weighing Scale Indicators

Weighing scales have been an integral component of industrial operations for decades. Weighing scales are used for a variety of applications right from check weighing, part counting to livestock weighing. Moreover, the application of scales is not just limited to manufacturing operations, perhaps scales find a wide range of applications in warehouses, laboratories, etc. What makes the overall weighing process easier are different types of weighing scale indicators. Digital weighing scales are often equipped with inbuilt indicators. However, separate weighing indicators can be retrofitted to existing weighing scales and balances to be used alongside the unit.

What are Weighing Indicators?

Digital weighing indicators alternatively know as weight indicator is a devices that displays weight values digitally in order to make them readable. The weight indicator allows the weighing scale operator to monitor the weight of the given specimen. Most indicators have this basic function of indicating weight. However, several indicators also function as scale controllers.  For example, batching Indicators are available with potentially free relay contacts for batching operations.

Nevertheless, the extent of application of weight indicators varies with the functions or depends completely on the operation they carry out.

Weighing Indicator Construction:

Weight indicators are often subjected to heavy usage and handling. Thus they are constructed with damage-resistant and sturdy casing to sustain different industrial settings. Additionally, scale indicators may come with a stand for mounting purposes. Moreover, they are equipped with LCD displays with color-coded function keypad buttons as well as numeric buttons. The modern LCD display comes with a backlight pre-installed, which enables users to read easily read output readings. Also, these indicators are equipped with sub-displays that show weight, setpoint, cumulative value, and error message, etc. on the same screen.

What are Weight Indicators Used For?

Scale indicators are basically secondary devices, acting as an additional display that can be used alongside the main weighing scale. However, these indicators do not have control functions. Weight indicators are available in various sizes. Most often large displays are preferred in industries using heavy-duty weighing scales, which allows operators to read scale output from a safe distance.

How Does a Weight Indicator Function?

Scale indicator transforms the electrical output from a weighing scale into values that are delivered to the operator visually or digitally via LCD display. Nevertheless, if the weight indicator is incorporated into a bigger system, the weight readings of commercial scales will assist in regulating the processes and function as scale controllers, depending on the programming.

What Factors to Consider While Selecting Weight Indicators?

The selection of scale indicator will depend on the environment it will be used in and the functions it needs to perform. For example, if you need to use a weight scale in an industrial setting then the indicator must be sturdy to withstand a harsh industrial environment. Additionally, the indicator must be able to meet process requirements perfectly well. The indicator must be able to produce accurate as well as precise reading every time it is being used.

Here are the different types of weighing scale indicators;

  • Basic Indicator

It is a basic weight indicator that converts and displays load cell outputs as weights. These scales are equipped with all the basic functions required for platform scales etc. However, there are many options available in the market that can perform a range of applications such as check weighing and packers. Some more advanced functions may include normal batching, loss in weight sequence, batch time monitoring, mixing functions and sequencing functions, etc. In the case of scale repair, these indicators are easy to retrofit.
  • Universal Indicator

Universal indicators are often equipped with an Ethernet connection. These indicators are utilized in tank weighing, road weighbridges, platform scales, and retrofit applications. Universal weighing scale indicators have features like least count through the keypad, high-speed A/D conversion, selectable weighing capacity, and battery backup which is optional.
  • Batch weighing Indicator

This scale also comes with features such as selectable weighing range, optional real-time clock, easy replacement of indicator system and optional battery backup, etc.
  • Flameproof Weighing Indicator

In order to protect the scale from extreme heat and other harsh conditions, these scales are provided with cast aluminum casing. Its construction makes it suitable to be used in the vicinity of materials such as petroleum-based products or paints. These scales can easily withstand dangerous working conditions. Apart from sturdy construction, these scales are often provided with the main display, sub-display, and various weighing functions.
  • Check Weighing Indicators

These indicators are excellent to be used on platform scales and conveyors. The indicator displays a bar graph that checks weighing items on the conveyor. The graph shows whether the given item falls into the specified weight range or not. Advanced versions of this scale are equipped with convenient check modes to make the weighing operation easier.

These are some of the most commonly used weighing scale indicators that are available today. Contact us, if you want to find out more about quality scale indicators.
