INTERFACE WIRELESS LOAD PIN SOLUTIONS
By embedding robust wireless transmitters directly into our precision-machined load pins, you gain continuous, reliable load monitoring, from lab to hazardous environments, completely cable-free. Interface offers standard and custom load pins, as well as configured load shackles which use the load pin sensor.
Machined from high-tensile stainless steel and normally supplied complete with a keeper plate, all our load-measuring pins are built to exacting standards and proof-loaded to 150% of the normal rated load. The unique wireless housing is manufactured from semi-aromatic polyamide plastic, making the load cell far more compact and reducing overall product weight.
Interface wireless load pins easily connect with a range of instrumentation devices, from transmitters to displays, for immediate analysis or monitoring. The Interface WTS Wireless Telemetry Systems devices support simple displays with handheld units or complex setups with multiple load cells and wireless devices.
The Interface S-Type Load Cell is a highly versatile miniature sensor capable of handling both tension and compression. The configuration offers a small, symmetrical design that keeps the sensor aligned with the force path, making it ideal for OEM integration, suspended loads, mechanical scale conversions, and compact test machines. As detailed in Tips for Properly Installing S-Type Load Cells, the four fundamentals for a successful installation include: counteract torque at the source, observe the thread depth rule, lock hardware
mechanically, and upgrade hardware for higher capacities.

TEMPERATURE COMPENSATION 101
Temperature compensation minimizes a load cell’s thermal sensitivity in its output and zero balance. Without compensation, thermal expansion, contraction, and changes in material elasticity can cause measurement drift, compromising data integrity. Interface provides detailed temperature specifications for our sensors in the product data sheet, enabling
engineers and test lab technicians to build highly accurate error budgets and test plans.
By defining the exact thermal limits, testing professionals can quantify potential uncertainty before a test begins. The temperature performance specifications when selecting a load cell enable technicians to determine whether environmental controls are necessary, calculate expected baseline shifts, and ensure the sensor remains within its calibrated accuracy range during dynamic thermal cycles.

TECH TALK: UNDERSTANDING THE DYNAMICS OF SETPOINTS AND RELAYS
Understanding setpoints and relays, and how they interact with sensor hardware, is critical for system safety, preventing overload, and achieving automation and testing objectives. A setpoint is a digital or software-defined threshold value programmed into instrumentation that corresponds to a specific measurement target. The instrument continuously compares the live, processed load cell variable against this threshold to determine whether an action is needed based on predetermined criteria. The relay is the physical or electronic switch that performs the mechanical work. When a setpoint condition is met, the instrumentation sends a signal to change the relay’s operational state, opening or closing an external electrical circuit.

ILLUSTRATING IMPACT TESTING
An impact test is designed to yield far more than a simple visual confirmation of a component breaking. Without capturing the exact force-time curve or determining the precise moment at which a crack propagates through a material matrix, you cannot calculate critical metrological metrics such as fracture toughness or dynamic yield strength. Interface provides a wide range of products for impact testing, including fatigue-rated load cells, overload-protected miniature load cells, load pins, reaction torque transducers, signal conditioning instruments, data acquisition systems, and wireless telemetry systems. Surviving the physical impact is just part of the challenge in high-velocity testing. The true test is ensuring your instrumentation withstands structural loads without compromising measurement accuracy. Get more insights in Impact Testing for Millisecond Assessments.
TOP FAQS ABOUT USING LOAD CELLS FOR WEIGHING
Successfully integrating load cell technology into a high-precision weighing system requires an understanding of how physical, environmental, and electrical factors affect performance. The sensor, especially the load cell, is central to weighing systems today, converting mechanical force into an electrical signal for accurate measurement. Interface engineers address challenges and common questions about sensor use in high-accuracy weighing, including how to quantify accuracy, options for outdoor use, choosing cables versus wireless
connections, ensuring structural stability, selecting appropriate instrumentation, managing signals, and essential calibration and maintenance procedures. Learn more in Top 10 FAQs for Weighing and Load Cell Integration.
