I want to experiment with a load cell. A main pulley has a belt with a fixed tension on it for example 50LB. When the main pulley is turning it will lift a load of approximately 125lb. The belt under load will then have 50 + 125 = 175lb on it. I want to measure the force against the idler pulley for both sides of the system and have the prop read the load and evaluate for problems. I see tons of load cells on line, does anyone have any experience with something more industrial for this application? I need something very reliable. I am working on trying to find out the formulas for determining the force against the sensor.
