Bridge Completion 1

Bridge Completion Considerations

Interface's use of the Wheatstone bridge is considered world-class in load cell design and for its ability to produce accurate measurements. Selecting the right instrumentation and ensuring proper bridge completion are technical necessities for maintaining the integrity of your force measurement data. Our bridge completion solutions simplify selecting the right instrumentation device to pair with your sensor, making it easier than ever to achieve high-quality measurements.
Force Versus Pressure

Distinctions of Measuring Force Versus Pressure

Interface strain gage load cells are the most reliable and accurate sensor for measuring force, as it's specifically designed to capture the total mechanical load. In contrast, a pressure sensor is designed to measure force distributed over a known area. While it is possible to design a load cell to measure pressure like Interface's IPCD, load cells are commonly used because they are specifically engineered and calibrated to measure total force accurately. Attempting to measure force with a standard pressure sensor is problematic because its output depends on both the force and the area over which it's applied. If the force distribution changes, the sensor's reading will change even if the total force remains constant. This makes a pressure sensor an unreliable tool for measuring the total force applied by a solid object.
INTERFACE TECH TALK Resistance Output Vs Rated Output

Resistance Output Versus Rated Output

Rated Output (RO) is the dynamic electrical signal that directly represents the applied mechanical force. Resistance Output is a static electrical characteristic of the load cell's internal circuitry. When you are performing force measurements, you are primarily interested in the Rated Output. This value, in conjunction with your excitation voltage, enables you to accurately convert the measured millivolt signal into engineering units of force in lbf or Newtons.

INTERFACE TECH TALK Overload Detection

How Does Load Cell Overload Detection Work?

Load cell overload occurs when the force applied to a load cell exceeds its rated capacity. Load cells are designed to operate within specific load limits. Overload detection is essential to protect these costly and sensitive devices from damage and ensure the longevity and reliability of the sensors. Without proper overload protection, these sensors can be compromised, leading to inaccurate readings or permanent damage.
