The Force sensor BT42i measures pushing and pulling forces in two measurement ranges, between -5 and 5 N and between -50 and 50 N. The switch allows selecting either of two ranges. To measure force the Force sensor uses strain gauge technology.
A maximal force of 80 N can be applied to the sensor, for forces above 80 N the sensor can be damaged permanently.
Several accessories are included with the Force sensor: a bumper to use for collision experiments, or any time you want to measure pushing forces, a hook to use to measure pulling forces, a thumb screw to mount the sensor on a ring standard and a utility handle to mount the sensor to various clamps.
The Force sensor can be used as a replacement for a hand-held spring scale, can be mounted on a ring stand or on a dynamics cart to study collisions. It can also be used to:
• study simple harmonic motion,
• measure of centripetal or frictional forces, or
• study Hook's law.
The Force sensor can be directly connected to the analog BT inputs of the CMA interfaces.
The sensor cable BT - IEEE1394 needed to connect the sensor to an interface is not
supplied with the sensor and has to be purchased separately (CMA Art. Nr BTsc_1).
Technical specifications of the sensor are described in its User's guide
