Potentiometer-Based Position Transducer Voltage Divider and Power Calculator.Voltage Conditioner Zero-Span Calculator.Position Transducer Linearity (Calibration).Displacement Cable Sag (Catenary Curve).relatively short length of cable exposed to the excitation sourceįundamental frequency and the harmonics associated with that frequency.small mass of the cable per unit length.The fundamental frequency of most SpaceAge Control position transducer cables is rather high due to 3 factors:
The fundamental frequency of a position transducer cable can change based on the amount of cable exposed to the excitation source and the cable tension which varies according to the displacement of the cable. The purpose of the above calculator is to provide a tool to estimate the fundamental frequency of SpaceAge Control position transducer cables. While such resonance is very rare and difficult to achieve, it is possible. As such, the cables on these sensors have fundamental frequencies that may cause the cable to resonate. L (cable length exposed (outside of the transducer))ĭraw wire transducers (also referred to as wire sensors and cable displacement transducers) are subject to the same laws of physics as musical instruments. Into all cells in the Assumptions section and press Calculate. This calculator provides the fundamental frequency of a cable (string) under tension. Keep in mind that theta and the distance the string has been pulled are related, and solve algebraically.The Miniature, Rugged Alternative to LVDTs and Linear PotentiometersĬable (String) Fundamental Frequency Calculator Basically, you’re going to want to find the distance the string gets pulled where the force of the motor (equal to sin(theta)*torque/arm length) equals the spring constant K times the length the string has been pulled. How far the string gets pulled downward depends on what it’s connected to, but if it’s just connected to a fixed object, the distance it gets pulled downward will involve the spring constant of the string and it’s length. The force downward is related to the angle the arm of the motor makes with the vertical by a sin function.
This should be in Nm, in*Lbs, or some other distance times a force, so when you divide the torque (lets say in Nm) by the length of the arm you’re using (lets say in meters) you get the force exerted by the motor (in this case in newtons). Physics Compute mechanical work: Compute centripetal acceleration: Do a gravitation calculation: Analyze a harmonic oscillator: Analyze the motion of a. To calculate the force which the string being pulled down upon can see, look up the stall torque of the motor you’re using.
