About project observation in commonly used sensor

The sensor was measured that the physical quantity transforms for with it should, and easy to examine, the transmission or the processing signal attire sets. The sensor is test system’s key link, is shouldering the signal conversion, no matter what serves, if strength, stress, pressure, External Drive Magnetic Transducer torque, displacement, speed, Canadian speed, temperature, current capacity and time and so on was measured the non-electrical quantity transforms with it to should, easy to process and the transmission electric power (voltage, electric current) or the electricity parameter (resistance, inductance and electric capacity and so on). Sensor’s performance direct shade is making a sound the entire test and control system’s operational reliability.
The sensor may divide into two broad headings according to its principle of work: One kind is the electricity generation type sensor, it transforms the non-electrical quantity into the electromotive force. The example like, the voltage Self Drive Magnetic Transducer which sends out using the generator the characteristic which is proportional with its rotational speed, may take the small generator the survey rotational speed the sensor. Leaves can have the electromotive force in this kind of sensor itself, therefore cannot want the external power. Another kind is the parameter type sensor, it measured that the non-electrical quantity transforms into electricity parameter and so on resistance, inductance and electric capacity changes, like resistance strain gauge type sensor, inductive transceiver and electric capacity sensor and so on. This kind of sensor must want the external power generally.
Sensor’s output electricity surely must with measure that the non-electrical quantity has the monodrome function relations, and can as far as possible for the linear relationship. Requests the sensor to have the high precision and the sensitivity, good stability and dynamic characteristic. Outside this also requests SMD Transducer the knot to construct Jan Dan, durable and the seal is moisture-proof, has certain anti-knocking performance and to surveys the environment to have the strong compatibility.
