Interface Calibration 101

Calibration of force and torque sensors is critical to receiving accurate data from measurement testing.  Calibration is the comparison of the instruments output against the known standard of measurement. For a load cell, it is the comparison of the load cell output against the standard test loads.

The calibration ensures the sensor is performing accurately and set for ideal output based on the capacity and configuration of the design. A standard calibration tests repeatability and linearity, which are both used to determine the accuracy. Calibration tests are run to identify any potential measurement errors caused by zero offset, non-linearity, hysteresis, non-repeatability, and shifts from zero.

The team of calibration experts at Interface are specifically trained to provide this specialized service as part of our quality and lab standard requirements of operations. Interface is ISO/IEC 17025:2017 and A2LA Accredited for Torque and Force Calibration in accordance with the recognized International Standard ISO/IEC 17025:2017.

Interface certifies all our load cells with accredited calibration before releasing the product for shipment. Certificate information includes tabulated measurement variables data, zero balance, computed nonlinearity and hysteresis, and traceability statements. We are often recognized as the most complete calibration certification in the industry

In a recent customer survey, we found that one of the most important roles that Interface force measurement solutions play is for our calibration services. This is due to the accuracy, reliability, and dependability over long periods of time of the load cells we manufacture and service.

Why Calibrate?

Calibration is important based on many different factors, including continued performance, safety, and compliance with ISO or industry specific standards. Interface’s standard recommended calibration interval is to recalibrate every 12 months. The frequency of calibrations should be determined by the following use case factors that may affect measurement accuracy:

  • Measurement quality and allowable tolerance range
  • Level of stress to which the equipment is subjected
  • Stability of past calibrations
  • Required measuring accuracy
  • Quality assurance requirements

Calibration Services Process

The Interface calibration team consists of a team of professionals dedicated to an optimized calibration and repair process for timely management of our customer’s requests. We begin the calibration service process with our technical services group who manage the request and RMA process, in addition to evaluation and troubleshooting.

We evaluate all products at our headquarters with our team of experts. The sensor goes through a thorough inspection process to identify any necessary repairs and to ensure device is in working condition in preparation of a calibration. This includes an electrical test. Based on the extensive evaluation, if the device is found to be unrepairable, there is no charge. We also will work to find a replacement unit. All work beyond the evaluation is sent to the customer for approval.

The final step in our calibration services process is the actual calibration. Our calibration team is considered the most experienced in the industry due to the sheer volume of work product they calibrate every day.  Interface also is heavily invested in conducting all our calibrations with the most advanced equipment, including our proprietary Gold Standard® and Platinum Standard® systems. These machines ensure that the transducers are calibrated to the most accurate ability possible before returning to the customer.

Even the most high-end manufactured load cells and finely tuned components endure accuracy degradation over continued use. To ensure your sensors are always ready for peak performance, check out our calibration services request form. We also provide a full range of calibration grade products for metrology and testing labs. You can also give us a call at 480-948-5555 to discuss your specific calibration needs.

 

Engaging Interface Calibration and Repair Services Expertise

A high-quality load cell is a critical piece of technology for the design and testing of products throughout various, highly regulated industries including medical, aerospace and defense, automotive, and industrial automation. To get the most out of a load cell, just like anything else, you need to understand how to care for and maintain it. A poorly maintained load cell can lead to inaccurate data and poor performance.

Interface Calibration and Repair Services provide a valuable function for our customers in recalibration and technical support for the thousands of products manufactured by the leader in force measurement.  When cared for properly, a load cell should to be calibrated once a year or at least every two years under regular use. There are also certain circumstances where a load cell is damaged in use and needs immediate repair. Interface can handle calibration and repair of any load cell on the market, whether we build it or not.

A key differentiator for Interface is the fact that our calibration lab is ISO 17025 and A2LA accredited. These accreditations are typically for major calibration labs, not in a manufacturer’s facilities like ours. Our deep expertise in the development of load cells allows us to provide the highest quality calibration and repair services on the market because we know the product inside and out.

Interface’s Industry Leading Calibration and Repair Process

The Interface calibration team consists of 10 individuals dedicated to an optimized calibration and repair process that gets our customer’s load cells in and out as quickly as possible. The process begins with the front-end team, who manages the customer’s request, goes through the RMA process, and troubleshoots any additional concerns with the customer.

Once we review the product in-house at our Arizona headquarters, the load cell goes through a thorough inspection process to identify any necessary repairs and to ensure the load cell is in working condition for calibration. This includes an electrical test to evaluate if the load cell is in proper condition to calibrate. It’s also important to note that if the load cell can’t be repaired, there is no charge to the customer, and we work to find a replacement unit. The customer also approves any repairs that are necessary before work begins.

The final step in the process is the actual calibration. Our calibration team has many years of experience and know load cells inside and out. We also work with the most advanced equipment, including our proprietary Gold Standard® and Platinum Standard® systems. These devices ensure that the load cells are calibrated to the most accurate capability possible before returning to the customer. More information about Interface Calibration Systems can be found in our Calibration Systems 101 blog here.

Our commitment to building quality calibration systems is evident by the customers who also use them to do calibration in-house. In fact, in nearly every major manufacturing testing lab, you will find an Interface Gold Standard Calibration System and Gold or Platinum Standard Load Cells. This is because our customers are working on some of the most advanced hardware in their respective industries and fields. Engineers and testing labs trust Interface for accuracy, performance and quality.

Interface customers not only need to ensure their measurements are as accurate as possible to avoid product failure, they also need to prove the accuracy of their testing equipment for those products to pass inspection and make it to the market. We provide both our expert calibration services in our calibration lab, or through high-quality, high-reliability systems available that we build for our customers.

Calibration for Crane Scale and Dynamometer Applications

Interface is well-known for excelling at calibration services for load cells. Did you know this service excellence extends to dynamometers and crane scales?

Interface can calibrate dynamometers and crane scales with capacities of 100,000 pounds of force or more. This family of devices is often found in industrial, commercial, energy, military, and aerospace industry applications.

Crane scales are used as overhead weighing solutions ranging from light to heavy capacities and are normally placed in the load string of a crane. The devices provide crane overload protection, as well as information about the handling of bulk material.  Some models are equipped with wireless communications to allow monitoring from safe distances at multiple locations.

Dynamometers, which are sometimes referred to as tension links or dyna-links, are also used in many overhead weighing applications. These devices are usually smaller and lighter than crane scales allowing them to be used in vertical and horizontal positions.  In addition to weighing and crane overload protection applications, dynamometers are often used for crane certification, elevator certification, and several other inline test and measurement applications.

What really makes Interface different when it comes to our calibration services for crane scales and dynamometers?

First, our calibration equipment is custom-made for this exact purpose. That means we don’t take a one-size-fits-all approach to your specific calibration needs, giving you the peace of mind that your calibrations are done correctly.

Second, we have decades of experience providing industry-leading service and putting our customers first. We are sought out for this service for a reason—because we get it done right.

Additionally, Interface does not use hybrid systems for its calibrations. We use direct force application and NIST traceable force standards with customized fixture assemblies for each type of equipment. These important distinctions allow us to focus on providing the best-accredited calibrations for crane scales and dynamometers available in the industry.

Not only are we recognized experts in calibration services, but Interface is also known globally for reliability, accuracy, and longevity of its products.
