Q&A on ultrasonic sensor technology

Tension and compression sensors are one of the load cells. A device that converts physical data signals into accurately measured electronic signal outputs. It is widely used in industrial production weighing equipment, platform scales, electronic scales, hook scales, batching scales and other dynamometers. But different types of tension and compression sensors are used differently, and now ...

Ultrasonic sensors are used for the inspection of printed circuit boards (PCBs), where ultrasonic sensors are used to inspect printed circuit boards. So what factors need to be considered when installing and installing ultrasonic sensors? Ultrasonic sensors are capable of being installed and operated in any orientation, ...

Load cells can be wired in two different input and output ways: One is the four-wire connection method The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and the time and time of use are very convenient, but when the cable is long, it is very simple to be affected by the working temperature.

1. The core is different: the core of the communication contactor will suffer eddy current and hysteresis loss, while the DC contactor has no core loss. Therefore, the core of the communication contactor is made of mutually insulated silicon steel sheets, and is often made into an E-shape; The core of the DC contactor is made of a single piece of mild steel, ...

Unlike load cells or force transducers, the measuring body of a torque transducer is not subjected to a tension load during operation, but is affected by the lever torque or torque, which can be changed. Therefore, torque sensors require special strain gauges to measure this type of load, i.e. torque. Canon...

The rotary incremental encoder outputs pulses when it rotates, knows its orientation by the counting device, and remembers the orientation by relying on the internal memory of the counting device when the encoder does not move or the power goes out. In this way, when the power goes out, the encoder can not have any movement, and when the call is working, the encoder ...

Encoder: Laser encoder is a general term for encoders with laser as the light source. According to the published material, the principle can be broadly divided into two types, namely the use of the grating method and the use of the Fourier image method. Grating thousand-related method, where a laser of wavelength is projected on a periodic grating at a distance of p, ...

The first is pressure, and the transmitter can't afford to lose it. In this case, see if the pressure connector is leaking or clogged, if you admit that it is not, look at the wiring method and see if the power supply is normal, simple pressure to confirm if the output has changed, or if there is an output at the zero point of the sensor ...

There are two common types of sensor switches: NPN type and PNP type, so what are the differences and differences between them? For example, there is a switch VT in the NPN open collector output circuit, and the output OUT is through the switch ...

1. The displacement sensor is a device that converts the motion displacement of the object into measurable electrical quantities. It is usually used to convert physical quantities such as displacement, orientation, deformation, oscillation, and size that are not convenient for quantitative detection and processing into electrical quantities that are easy to quantitatively detect and facilitate information transmission and processing. ...

In electrical intrinsic safety explosion-proof (abbreviation: intrinsically safe explosion-proof), we generally divide the workplace into explosion-proof area and non-explosion-proof area. There is the transmission of electrical energy between the explosion-proof area and the non-explosion-proof area, for example, the switches, buttons, sensors, etc. in the explosion-proof area are connected to the non-explosion-proof area through the wires.

Rotary encoders are a class of sensors used to detect the angle of rotation and its derived mechanical parameters, including velocity and acceleration, etc., and can detect transmission movements such as rotation and linear lines. Due to its widespread use, rotary encoders convert mechanical inputs into electrical signals, which can be used by counters, tachometers, programmable...

Strain gauge tension and compression load cells are available in two different input and output wiring methods: The first is the four-wire connection method. The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and it is very convenient to use, but when the cable is long, it is easy to be shaken by the operating temperature.

(1) Conductive plastic displacement sensor Conductive plastic displacement sensor uses a special process to coat the DAP (didipropylphthalate) resistance paste on the insulating body, heat and polymerize to form a resistive film, or press the DAP resistive powder thermoplastic into the groove of the insulating matrix to form a solid body as a resistor.

In many applications, there are certain safety requirements not only for the sensors in use, but also for the sensor cables. In order to ensure that the adapter components also meet these requirements, the new cable maintenance system provides the ambition for sensor adapters, cable conduits and cable glands ...

According to the principle of operation: Potentiometer-type displacement sensor It converts the mechanical displacement through the potentiometer element into a resistive or voltage output that is linearly or arbitrarily linked to it. Generally, linear potentiometers and round potentiometers can be used as linear and angular displacement sensors, respectively. ...

Direction and fluid flow velocity sensors are essential for different industrial, medical, and environmental uses. Flow sensors quantify the direction and rate of gas and liquid flow in applications such as density measurement, viscosity measurement, flow pattern determination, and wall shear stress determination. In addition to the flow parameters to the direction, ...

Under normal circumstances, a photoelectric sensor consists of two parts: a processing path and a processing element. Its basic principle is to use the photoelectric effect to convert the measured change into a change in the optical signal, and then use the optoelectronic components to further convert the non-electrical signal into an electrical signal. The "photoelectric effect" refers to the use of light ...

A smooth production process is the policy that every production manager strives to achieve. In order to accomplish this policy, a high-performance automation system is required. With the new FDH-1 handheld bus diagnostic device, you will be on your way to maximizing the availability of your equipment.

In the early application and selection of sensors, how to choose is a very important point, and the selection is smooth, and the following will briefly say how the sensor is selected in the early stage. The Viewpoint Sensor is in the real ...
