What kind of sensor is used in DC circuits What kind of sensors are used in AC circuits in 10

For general acoustic emission applications, the signal frequency band range is mostly between 25kHz and 750kHz, so resonant sensors are more suitable. Resonant narrowband sensors with a general broadband frequency of 150kHz are commonly used for metal materials and other applications; For acoustic emission signals such as corrosion and leakage, resonant sensors with a resonant frequency of 40kHz are commonly used; Due to the relatively low response sensitivity of wideband sensors in a wide frequency band, wideband sensors are selected for spectrum analysis. Qingcheng acoustic emission sensor is made of high-quality stainless steel material, and the overall shielding design can effectively reduce interference; It is suitable for bridge wire fracture monitoring, valve pipeline leakage monitoring, tool wear monitoring, wind power equipment monitoring, rotating equipment acoustic emission monitoring, structural parts damage monitoring, storage tank floor acoustic emission monitoring.

The current transformer is used in AC, and the shunt is used for the detection of DC current, and many sensors can be used for both DC and AC (the sensor comes with a rectifier), and the sample is checked.

It has something to do with Hall elements.

How many ways can the sensor be powered? What does each do?

How many ways can the sensor be powered? What does each do? Hello dear, the sensor can be divided into two types: active and passive according to the form of action.

Active sensors are further divided into action type and reaction type. This kind of sensor can send a certain detection signal to the measured object, can detect the change of the detection signal in the measured object, or form a signal by the detection signal in the measured rock ephemeral. The mode of detecting the change of the detection signal is called the action type; The detection is formed by the response, and the signal mode is called the reaction type.

Radar and radio frequency range detectors are hands-on examples, while photoacoustic analyzers and laser analyzers are reaction-type examples. Passive sensors simply receive signals generated by the object being measured. For example, infrared radiation thermometers, new and external camera devices, etc.

According to the form of energy supply for changing work, the sensor can be divided into two types: energy conversion type and energy control coarse search type. The energy conversion sensor does not need to provide additional energy when converting the signal, that is, it does not need an external power supply** to convert the signal energy into another form of energy output. This type of sensor is mainly composed of energy conversion, such as sensors based on piezoelectric effect, thermoelectric effect, photoelectromotive force effect, etc.

For example, solar cells and piezoelectric accelerometers, among others, are examples. When the energy control sensor converts the signal, it needs to supply energy first, and the energy needs to be supplied by an external power supply) The energy supplied by the input signal is controlled by the input signal, and the change of energy is detected to form an output signal. Circuit parameter sensors such as resistance, inductance, and capacitance belong to this type of sensor.

Sensors based on strain resistance effect, magnetoresistive effect, thermal resistance effect, photoelectric effect, Hall effect, etc., also belong to this type of sensor. For example, resistive strain sensors and phototransistors are actually inverted. Hope it helps.

A common circuit used to identify the phase of the AC signal of an inductive sensor is the phase detection circuit. This circuit usually consists of an amplifier, two diodes, some resistors, and capacitors. It works by amplifying the AC signal of an inductive sensor through an amplifier and then phase sensing through two diodes.

When the phase of the AC signal of the inductive sensor is the same as the phase of the reference signal in the circuit, both diodes turn on, so that the phase of the AC signal of the inductive sensor can be determined by detecting the current in the output circuit. In addition, there is a circuit called a hysteresis comparison circuit, which can also be used to identify the phase of the AC signal of an inductive sensor. The principle of the hysteresis comparison circuit is that the AC signal of the inductive sensor is processed through a hysteresis network, so that the phase of the processed signal lags behind the phase of the reference signal.

Then, the processed signal is compared to the reference signal, and the phase of the AC signal of the inductor sensor is determined by detecting the current in the output circuit.

Sensors have a wide range of applications in a variety of applications, mainly in the following areas:

Monitoring and control: Sensors can be used to monitor environmental parameters such as temperature, humidity, pressure, light, etc., and then pass this data to the control system for analysis and control.

Safety and protection: Sensors can also be used for safety and protection applications, such as fire, gas leaks, liquid level detection, etc., when the sensor detects an abnormal state, it will sound an alarm or trigger other protection mechanisms.

Medical and health: Sensors can also be used in medical and health applications, such as heart rate monitoring, blood pressure monitoring, body temperature monitoring, etc., which can help doctors and patients to diagnose and improve the efficiency of medical water cavities.

Smart home and Internet of Things: Sensors are also widely used in smart home and Internet of Things, used to monitor the indoor environment, control home appliances, smart home security, etc., to achieve intelligence and automation.

Industrial manufacturing: Sensors are also an important part of industrial manufacturing, which is used to monitor the status of equipment, detect product quality, control production processes, etc., to improve the efficiency and intelligence level of industrial manufacturing.

It is a great honor to answer for you that AC electromagnetic sensors and AC sensors both work on the same principle and have the same properties. AC sensors are also a type of electromagnetic sensor because AC sensors use alternating current to generate a magnetic field (flux) in a coil that allows the sensor to engage. In addition to AC sensors, there are also DC sensors and permanent magnet sensors, all of which belong to electromagnetic sensors.

Extended information: AC current sensor (AC current sensor, AC current transducer) is a device for detecting AC current, which can feel the information of the measured AC current, and can transform the detected and felt information into an electrical signal or other required form of information output according to a certain law, so as to meet the needs of information transmission, processing, storage, display, recording and control. It is the first link to realize automatic detection and automatic control.

Electromagnetic current transformer is a special type of transformer, referred to as current transformer. Under normal use conditions, the secondary current is essentially proportional to the primary current, and the phase difference is close to zero when the coupling method is correct. Secondary windings are used for measuring instruments, gauges, relays and other similar hail calendar appliances.

Rogowski coil is also known as Rogowski coil, Rogowski coil or hollow coil. The Rogowski coil is a kind of AC current sensor, which is a hollow annular coil, which is flexible and rigid, and can be directly applied to the conductor to measure the AC current.
