INTERFACE 101 FLEXURES

Load Cell Flexures 101

Interface designs all of our load cell flexures. A flexure is a specially designed component that can bend under a load without breaking. They are used in sensors where precise, frictionless movement is needed, like measuring force. The flexure, a complex machined part, acts as the spring element. With thousands of models, capacities, and configurations, manufacturing our flexures is paramount to our load cell accuracy, quality, and precision performance.
INTERFACE 101 CREEP

Creep 101

Interface defines creep, an important accuracy specification for load cells, in the essential 101 Series. When a force is applied to a solid material within its elastic limit, the resulting deflection will subtly increase over time if the force is held constant. This phenomenon, known as creep, is not permanent but recoverable. It's important to note that the signal from a load cell exhibits this creep, making it a key consideration in all load cell applications.

Stress Testing 1

Load Cells Built for Stress Testing

Interface load cells are designed and manufactured for stress testing. Stress testing with load cells is an integral part of research, design, and manufacturing processes for various products and components. It helps to ensure that material, equipment, and final products can withstand the stresses they will be subjected to in regular use.
INTERFACE 101 EXCITATION

Excitation Voltage 101

An excitation voltage is needed to power the load cell and ensure the output signal is accurate. Load cell excitation is necessary to ensure the accuracy and reliability of load cell measurements. Interface provides electrical performance data on all specifications represented as VDC MAX, when applicable.  The data for excitation voltage is listed under the electrical section of a transducer model’s specification datasheet, along with other factors, including rated output, bridge resistance, and zero balance.
BENDING BEAM

Bending Beam Load Cell Basics

Interface bending beam load cells are part of our Mini Load Cell product line. They are available in a variety of shapes and sizes, with different capacities and ranges. Some of our most popular bending beam load cells include the MB, MBI, MBP and MBS. The use of bending beam load cells expands across industries and applications, for weighing scales, medical devices, industrial process controls, robotic designs, packaging machinery and civil engineering projects.
INTERFACE 101 SERIES ROD END

Rod End Load Cells 101

Rod end load cells are designed to measure the tension and compression forces applied to a rod or similar structure. This type of load cell consists of a rod with a threaded connector. The load cell's strain gage measures the deformation caused by the applied force. Interface Rod End Load Cells including our REC and WMC models, utilize proprietary temperature compensated strain gages for high-accuracy measurement. Rod End Load Cells 101 shares the benefits, common applications and available products for this style of high-accuracy load cell.
Load Cells Versus Piezoelectric

Load Cells Versus Piezoelectric Sensors

Load cells and piezoelectric sensors are used in all types of measurement applications. Interface load cells measure the amount of force or weight being applied to them. The amount of force is numerated by the capacity of the model design, such as 50lbf (pounds-force) or 5kN (kilonewton). Piezoelectric sensors work on the principle of piezoelectricity. They are made of materials that generate an electric charge in response to mechanical stress, such as pressure or vibration.
INTERFACE TECH TALK Moment Compensation

What is Moment Compensation?

Every Interface LowProfile™ load cell is moment compensated to minimize sensitivity to extraneous loads. Moment compensated load cells are designed to counteract the external forces or moments by using a configuration of strain gages and electronics that can detect and compensate for these forces. The strain gages are arranged in a way that allows the load cell to measure the force applied to it in multiple directions, and the electronics can then use this information to calculate the impact of external forces and moments on the measurement.
