Field Weighing Scale

Field Weighing Scales are tough and sturdy in construction with MS or SS corrugated flat surfaces employed for checking weights of chicken, fish, fruits, and vegetables. The weighing platforms are usually square-shaped with four supporting stands. The major difference apart from all other weighing scales is the digital display positioning.

The digital display will never easily be adhesive to any dirt or dust from external sources or from weighing materials as it is placed beneath the weighing platform. It will be more convenient for end-users to read and understand the figures popping up in the digital display during the weighing process,

Calibrations of Field Weighing Scales

In most businesses today, weighing scales are the core of the business which cannot be removed from the essential things of a shop. Weighing scales help to run your business smoothly as it helps for several purposes. Every buyer will check the product’s weight before they bill it. It is a fact that buyers will happily procure the product after measurement.

During the continuous usage of weighing scales in shops, it will cause heavy wear and tear to the machine, thus measurement accuracy may be affected. Even when a scale is placed under vibrations or with static electricity the machine may suffer. To eliminate accuracy errors, calibration should be done during particular intervals. Sometimes, even the premium quality Field Weighing Scales of high prices may not be accurate and need frequent calibrations.

How to Perform Calibrations for a Field Weighing Scale?

The first and foremost step is to clean your weighing platform with a neat cloth to remove any debris before calibration. A product of known standard weight is placed on the scale. The weight is recorded. If the denoted reading matches the standard reading within calibration tolerance, the scale does not need any further calibrations. If not so, the scale needs to be reestablished for a precise and acceptable state of measurements.

The interval of calibration is based on the factors such as utilization, environment and manufacturer recommendations. Some machines are calibrated once a month and for some others take up to a year for further calibrations.

Calibration Tolerance

Calibration tolerance is the maximum acceptable deviation accepted from the standard values. The calibration tolerance for specific weighing scales is determined by the International Society of Automation (ISA). As per quality regulations, a manufacturer should mention the accuracy and level of calibration tolerance within the user manual and machine package.

Factory Calibration

Factory calibration is a process of calibrating scales within the industrial facility before it reaches the end-user. People believe that factory calibrated scale is enough assurance for the accuracy of a scale and it need not be rechecked or calibrated when it is bought. This leads to a large misconception among people. Check out that the location of the factory and your living locations have differed in elevations, so accuracy may or may not be maintained for a scale.

Always make sure you perform on-site accuracy verifications for your weighing scales. Crown scales without fail perform factory calibrations of Field Weighing Scales and recommends users to perform on-site calibration before habitual working of the machine. Connecting with third-party calibration services is also a better quick fix for obtaining optimal accuracy. We Crown scales not only carry out third-party services, as well as execute the adjustments and help for repairs that recovers the standard within tolerance.

Legal-for-Trade Calibration

All commercial scales require legal-for-trade or trade-approved calibration. Every state and measurement inspector will check out the working condition of commercial scales for suitable calibrations. Most of the scales are NTEP approved with CoC (certificate of conformance) for its approval. This information is fixed with a metal plate on the Field Weighing Scale showing the capacity, model and manufacturer. To obtain these approvals for weighing machines, the company should be registered under the National Conference on weights and measures.

Why is Cleaning Essential for a Field Weighing Scales?

Without any other go, cleaning the weighing scale is very important. As people weigh raw meat on a Field Weighing Scale, the blood or meat particles may adhere to the weighing platform. If left uncleaned the machine may deliver inappropriate readings and possess unhygienic conditions. To prolong the life of the weighing machine, to comply with SOP’s, to minimize out-of-specification (oos) errors and for safety purposes of operators, cleaning is to be followed systematically to your weighing machines. The first step of your cleaning protocol is to prepare a written standard operating procedure of how and what should be cleaned.

Cleaning Protocols for Field Weighing Scales

  • Clean your weighing platform using disposable tissue or damp cloth.
  • Select mild detergent chemicals suited for cleaning your weighing equipment. The frequently used cleaning agents include 70% ethanol or isopropanol. The ethanol effectively cleans the debris and leaves no residue on the surface.
  • Acetone should not be used even if the weighing scale possesses sticky substances as it is not compatible with cleaning digital displays.
  • While cleaning, switch off and remove the plug of the digital Field Weighing Scale display.
  • If the digital display can be dismantled, then separate the weighing platform and clean it with a damp cloth and mild detergents.
  • Make sure no substances enter the gaps, nooks and corners of weighing machines.
  • Clean the nook and corner of the weighing scale.
  • Reassemble the weighing machine to the correct position after drying the scale parts.
  • Switch ON the machine and check for the proper performance of the weighing machine providing accuracy.

Parts of Digital Field Weighing Scale

A small square platform with cornered load cells for accurate weight measurements. MS or SS weighing platforms are connected with strain gauges that measure the force of the weight being applied to them. When a weight is placed on the scale, it is evenly distributed with the help of four raised legs of the scale. Strain gauge consists of a metal track where the force that deforms, stretches or flexes back. This deformation is converted to an electrical signal. This minimal resistance change runs as an analog to digital converter and then passes to a microchip which is collected as data. This data appears as numbers in a digital display.

Points to be Considered for Field Weighing Scale

Application

When you buy a weighing scale, verify it is made of hard metals to withstand even the huge weights. Especially for, Digital platforms weighing scale, more polished or smooth surfaces are not recommended. The polished surfaces will be an obstacle for positioning your materials as it may slip during the weighing process and does not provide you with reliable measurements. Most of the weighing scales are either corrugated or like a vessel with outside protections to hold the chicken.

Positioning

Field Weighing Scales should be positioned in a clean and strong place without a hazardous environment. The positioning place should not be damp always. As though when raw chicken is having moisture content, the machine should be cleaned with protocols complying with safety measures. Make sure you place your weighing scale without any environmental disturbances around the place.

Capacity

Check the capacity of Field Weighing Scales that you want to procure. The capacity may differ based on your application of a weighing scale. Thus recognize your need and then select your choice of weighing scale.

Modes and Software

Most scales are manufactured for straightforward weighing with single modes. It is recommended to choose a weighing scale that performs data accumulations, inventory of data, parts counting etc., These operations will be helpful to observe the inventory goods and sold goods. Some weighing machines are facilitated with graph outputs for record-keeping purposes.

Technical Support System

If your weighing scale has malfunctioned, misplaced or damaged, you should contact a technical support member. Crown scales provides a team of technical support engineers who rectify the errors and provide service for warranty periods.

Readability

Readability regulates how many decimal figures it has to show with perfect accuracy. The scales with larger capacities have smaller readability and vice versa. With the development in technology, scales with surface acoustic waves are gaining popularity.

Connectivity

Modern scales are designed with computer connections, printers, and other electrical devices for recording data, checking inventories, process tracking and documentation. This is a most helpful option for industry purposes.
