Description
Technical field
The utility model relates to a kind of sensor device.
Background technology
Existing displacement transducer generally adopts cylindrical potentiometer as sensitive element, and when measurement point and sensor generation relative displacement, the change in resistance amount of cylindrical potentiometer reflects the value of displacement, and the increase-decrease plan of resistance understands the direction of displacement.But there is the shortcomings such as easy to wear, resolution is low in potentiometer, and due to adjustment rotating shaft needs and the coiling wheel hub coaxial rotation of potentiometer, and wheel hub is communicated with external environment condition by the outlet of steel strand wires, therefore electrical structure cannot be completely isolated with external environment condition, the damage of potentiometer can be caused when external environment condition exists infiltration or humidity is larger, and potential safety hazard is brought to connected metering circuit.
Therefore, prior art needs further improvement and develops.
