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 standa
Sensor A sensor is a device or element that collects information on an object and converts it to a signal that can be processed by a machine. Geomagnetic sensor Geomagnetic sensors can determine direction by detecting the geomagnetic field. Pulse sensor ROHM is developing an optical transmission ...
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 ...
A color sensor is a type of "photoelectric sensor" which emits light from a transmitter, and then detects the light reflected back from the detection object with a receiver. A color sensor can detect the received light intensity for red, blue and green respectively, making it possible to dete...
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...
A CMOS image sensor is a semiconductor device with complementary metal oxide semiconductor (CMOS) technology designed to turn incoming light into a digital image. Like most digital cameras, it detects incoming light with thousands of photon detectors on the surface of a semiconductor chip. Each dete...
Principle DC Leakage Current Sensor develops based on magnetic modulation closed loop principle, to measure tiny current (mA level). DC leakage current measuring range can reach 0~±200mA. This sensor is used to measure current of signal system, circuit, and l...
A vibration sensor is a detector that measures vibration levels in machinery, giving insight into the magnitude and frequency of vibration signals.
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. ...
