Load Rating can also be referred to as Tension Force. For example, if your application will be handling a 150lb load, Montalvo’s equation will give you a 300lb load rating, whereas others will give you the 150lb load rating. Montalvo doubles the resulting load rating. In other manufacturer equations “4Psin” appears as “2Psin”. Montalvo calculates load rating via the following formula: Others calculate load rating based on the load cells maximum operating capacity, whereas Montalvo focuses on calculating the load rating to optimize a load cells performance and longevity. How Montalvo Calculates Load Ratings: Montalvo’s calculation method for determining which load cells are best for your application varies from other manufacturers methods. Load Rating refers to the force you will be placing on the load cells. This is determined by the load cell’s load rating. After you’ve determined which brand and type of load cell is best for your application you will need to determine which size load cell is best for your application. Sensitivity ratings will vary among manufacturers, as well as the types of load cells themselves. This performance difference is what makes your control system faster, more accurate and reliable. This results in an application that responds faster and maintains proper tension throughout its process, maximizing productivity and profitability. Load cells with greater sensitivity are able to sense immediate and minute changes in tension through any noise that can be interfering with it. To ensure your controller is receiving the most accurate tension measurements, a load cell needs to be highly sensitive to any changes in the tension being placed on them. When making a machine as productive and profitable as it can be, choosing load cells with higher sensitivity ratios becomes imperative. This is because the load cell’s electrical signals are being measured and the control system is receiving less interference from machine noise. The HIGHER the signal-to-noise ratio the better. When the signal-to-noise ratio is lower, more noise is being measured/amplified rather than the load cell’s signal. The LOWER a load cells signal to noise ratio the less accurate your tension measurement becomes (ex: 20:1 provides significantly less sensitivity than 50:1). Often, noise includes mechanical movement that is translated into an electrical signal through sensors, amplifiers, and other machine sensory equipment.įactoring In Noise – As the signal coming from a load cell is amplified for the controller, so is any noise. Noise is random, non-grounded electrical signals produced by the components on the machine that interfere with the tension signal produced by the load cell. The greater this ratio means the greater a load cell’s signal resolution resulting in a higher signal to noise ratio, and thus greater sensitivity.Įxcitation Voltage is voltage required for the excitation of a circuit This equates to 50 mV per Volt or has a 50:1 ratio.

If a load cell has a 5 Volt DC (VDC) excitation voltage and a 0-250 mV output, the resultant ratio is 250mV/5VDC. When shopping for load cells, you are typically provided with two pieces of information about the load cell, excitation voltage (V orVDC), and output (mV).

Load cell sensitivity is defined as the minimum amount of force needed to cause a change in a load cells output. Resolution refers to the load cell’s ability to produce an output relative to the detected change.

The greater a load cell’s sensitivity, the better a load cell is at detecting the slightest changes in tension. Load cell sensitivity refers to the smallest force a pair of load cells can reliably detect.
