What is a current sensor? A current sensor is a detection device that can sense the information of the measured current, and can transform the sensed information into electrical signals that meet certain standards or other required forms of information output according to certain rules to meet the...
Barometric pressure sensor A barometric pressure sensor is a sensor that detects atmospheric pressure. Accelerometer sensor Accelerometer sensors are ICs that measure acceleration, which is the change in speed per unit time. Current Sensor A sensor that measures the current flowing in a circuit is cal...
General sensor A high-frequency magnetic field is generated by coil L in the oscillation circuit. When a target approaches the magnetic field, an induction current (eddy current) flows in the target due to electromagnetic induction. As the target approaches the sensor, the induction current flow ...
Since ultrasonic waves can reflect off a glass or liquid surface and return to the sensor head, even transparent targets can be detected. [Resistant to mist and dirt] Detection is not affected by accumulation of dust or dirt. [Complex shaped objects detectable] ...
What is a sensor? A sensor is a device that detects and responds to some type of input from the physical environment. The input can be light, heat, motion, moisture, pressure or any number of other environmental phenomena. The output is generally a signal that is converted to a human-rea...
The transducer is a device which converts energy in primary form into corresponding energy signal in the different form. the primary forms of energy include mechanical, electromagnetic, thermal, chemical, optical and more. As shown in the figure-1, transducer composed of a sensor and an actuator...
Comparison of various current sensor technologies TypePrincipleAdvantagesDisadvantagesApplicationsCost Current Transformer (CT) The current induced in a secondary winding is proportional to the primary current. Excellent accuracy, and high reliability. Limited bandwidth, size, and weight can be substantial. ...
A "sensor" is defined in the New Welsh dictionary as: "a device that receives power from one system, usually in another form, to a second system". In order to obtain information from the outside world, people must rely on the sense organs. But relying solely on people's own sense org...
What is a current probe? A convenient instrument that can measure current without shutting off the circuit Overview Many people use digital multimeters to measure properties such as current, voltage, and resistance. However, those instruments have a distinct disadvantage: to measure current with a ...
Proximity sensor: Calculates the distance to an object by measuring the time interval by transmitting a particularly short time and measuring the time from the emission of the light pulse to the reflection of the object. That is, for example, when you answer the phone and your face is close...
