Arc Position Sensors from CambridgeIC measure the angle of a rotating target relative to a fixed sensor - a challenge found in many systems.
They are positioned off axis, so that the rotation axis is free from sensor parts and any couplings. Arc sensors only extend along the measurement range of interest, so a complete sensor ring around the axis is not needed.
CambridgeIC Arc Position Sensors…
- Directly measure arc angle
- Eliminate mechanisms, bearings and couplingsOff-axis sensing - rotation axis clear of sensor parts
- Enable a big Gap between sensor and target
- Are truly non-contacting
- Are robust against mechanical shock
- Are tolerant of misalignment
- Are lightweight
- Can be completely encapsulated against dirt, dust, moisture
- Can be used in pairs, connected to a single CAM204 CTU processor chip
- Can be manufactured by the customer, for a cost effective solution that is well integrated with the customer’s product
Motorised surveillance cameras including PTZ cameras often have a tilt axis with limited angle range, for example 90° or 180°. Angle sensors measuring pan and tilt angle help the camera’s control system to point the camera in the desired direction, and to track objects moving in the camera field. An arc sensor helps to simplify the camera’s mechanics, because it can be positioned off axis and does not need precise alignment. Since the sensor only measures the 90° or 180° angle range needed by the application, it can be more compact than a conventional 360° sensor and delivers higher resolution as a fraction of the actual measuring range needed.
