Interface recently hosted an online technical seminar that detailed product specification basics, key values, terms to know, how to read a datasheet, what specs matter most in force measurement applications.
For Interface, specifications are detailed descriptions that outline the characteristics, features, and qualities of our products, systems, or services. Product specifications are included on all datasheets, detailing product performance, capabilities, capacities and dimensions. Products have internal specifications that are tested against during manufacture, typically with full traceability.
Throughout the webinar Demystifying Specifications, Brian Peters and Jeff White offered important tips on what to consider for high-speed, durability, precision, and specialty product requirements. They highlighted what to look for on the product datasheet when choosing a load cell or instrumentation device. This includes variables in specifications related to expected performance of transducers and instrumentation based on frequency, environment, and other critical testing application considerations. They also answered the most frequently asked questions of our applications engineers related to specifications and datasheets.

Detailing Product Specs for Specialty Sensor Products
Interface provides four types of specifications for every product we make and sell: functional, technical, performance and design.
Functional specifications describe the intended functionality or behavior of a product, whether a sensor, instrument or accessory. They outline what the product or system should do and how it should perform its tasks. Functional specifications typically include applications, product requirements, and expected use case results.
Technical specifications provide detailed information about mechanical aspects of a product or system. They may include information about the materials, dimensions, technical standards, performance criteria, capacities, and other technical details necessary for the design, development, and implementation of the product or system
Performance specifications define the performance requirements and criteria that a product or system must meet. This is critical in force and measurement. They specify the desired performance levels, such as speed, accuracy, capacity, efficiency, reliability, or other measurable attributes. Performance can be defined by a specific range, with maximum standards for peak performance. Performance specifications help ensure that the product or system meets the desired test and measurement goals.
Design specifications outline the specific design criteria and constraints for a product or system. These specs provide guidelines and requirements related to the visual appearance and can also reference the model details found in a product’s engineering CAD STEP file.

Key Force Measurement Specification Terms to Know
Nonlinearity: The algebraic difference between OUTPUT at a specific load and the corresponding point on the straight line drawn between minimum load and maximum load. Normally expressed in units of %FS.
Hysteresis: The algebraic difference between output at a given load descending from maximum load and output at the same load ascending from minimum load. Normally expressed in units of %FS.
Static Error Band (SEB): The band of maximum deviations of the ascending and descending calibration points from a best fit line through zero output. It includes the effects of nonlinearity, hysteresis, and non-return to minimum load. Expressed in units of %FS. SEB Output is a best fit straight line output at capacity.
Nonrepeatability: The maximum difference between output readings for repeated loadings under identical loading and environmental conditions. Expressed in units of %RO. In practice there are many factors that affect repeatability that ARE NOT included in the nonrepeatability specification.
Creep: The change in load cell signal occurring with time, while under load and with all environmental conditions and other variables remaining constant. Expressed as % applied load over specific time interval. Logarithmic effect that is also symmetric on load removal. Stated specifications may differ and are not for the same time interval.
Eccentric and Side Load Sensitivity: Eccentric Load – Any load applied parallel to but not concentric with the primary axis. Results in moment load. Side Load – Any load at the point of axial load application at 90° to the primary axis. Error influences are reported in terms % and %/in.

These types of products follow strict certification standards and ratings. During the online seminar, Interface product experts detail the standards and ratings related to intrinsically safe products, sometimes referred to as hazardous location use, as well as solutions designed to meet safety, regulatory or compliance requirements.
The standard ensures that an intrinsically safe device is incapable of triggering combustion or igniting any gasses or vapors. The device is safe to use around dust and gas without risking static electricity or heat discharge from the device igniting the surrounding volatile gasses, powders, and liquids. Explosion proof applies to a device enclosed in a case that can withstand a gas or vapor explosion. Should there be an explosion, it will be contained within the enclosure.
Interface offers products with different IP ratings, including IP66, IP67 and IP68 applied to different transducers and instrumentation. Ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids.
IP65 – Dust-tight, protected against water jets
IP66 – Dust-tight, protected against powerful water jets
IP67 – Dust-tight, protected against the effects of temporary submersion in water
IP68 – Dust-tight, protected against the effects of continuous immersion in water
What is the difference between IP66 and IP68? IP68 enclosures also provide dust-tight performance against solids. However, they are also rated for significantly better defense against water ingress than an IP66 enclosure. An IP68 enclosure can withstand submersion for over 30-minutes at up to a specified water depth.
Interface also has a range of instrumentation products that are NEMA, and IP rated based on the enclosure and housing designs. These include:
