Wireless Force and Angle Sensor Redy

Quick Answer: The Redy wireless force and angle sensor measures the push or pull applied to it and, as its title states, an angle as well, sending both wirelessly for logging. A force and angle sensor suits mechanics practicals in which the direction of a force matters as much as its size.

Force With Direction

Forces are vectors, and many school experiments are really about direction: resolving the weight of a trolley on a slope into parts along and across it, or finding the tension in two strings that hold a mass at an angle. A plain force sensor gives only the size of the pull. Recording an angle as well lets students log force and orientation together and calculate the component in any direction.

How the angle is measured is not described in the title; in similar sensors it is typically the tilt of the sensor body, read by a built-in inclinometer or accelerometer. That suits inclined-plane work, where the sensor is fixed to a ramp or trolley. The load range, and whether it reads pushes as well as pulls, should be established before heavy masses are hung from it.

For motion rather than force, the wireless motion sensor tracks a trolley’s position, velocity and acceleration, and the two data sets together test Newton’s second law.

Specifications

Applications

• Resolving the weight of a trolley on an inclined plane into components
• Friction: pulling a block at steady speed across different surfaces
• Hooke’s law: stretching a spring while force is logged
• Tension in strings supporting a mass at an angle
• Impulse: force against time during a collision

Care & Handling

• Zero the sensor in the orientation it will be used, with no load, before each run.
• Never exceed the rated load; sudden jerks overload a force sensor more readily than steady pulls.
• Fit hooks or bumpers finger-tight only, so the threads are not stripped.
• Store it unloaded, where it cannot fall.

Why Choose LabEquip

Physics teachers covering forces, vectors and Newton’s laws usually buy a force sensor for each practical group. LabEquip lists this one with its chemistry lab equipment; for load range and accessories, write through the contact page.

Frequently Asked Questions

Why does a force sensor need an angle reading?

The effect of a force depends on its direction. Knowing the angle lets you calculate the component acting along a slope or a string, which is essential in inclined-plane and equilibrium experiments.

How should the sensor be zeroed?

Hold or mount it in the position it will be used in, with nothing attached to the hook, and press zero in the software. Zeroing in a different orientation leaves the weight of the hook as an error.

Can it measure both pushes and pulls?

Many force sensors show pulls with one sign and pushes with the other. Check how this sensor reports each, and fit a bumper for pushing experiments.

How do I study friction with the sensor?

Pull a block along a surface at steady speed with the sensor and log the force. Add masses to the block to change the normal force, and compare the force needed on different surfaces.

Can the sensor measure the force in a collision?

Yes, if it samples quickly enough. Fit a bumper and let a trolley run into it; the area under the force against time graph gives the impulse, equal to the change in momentum.

What happens if the sensor is overloaded?

The reading stops rising, or the internal element can be permanently bent and give wrong readings afterwards. Stay within the rated load and avoid dropping masses onto the hook.
