Solutions for ultrasonic sensor applications

1. Test for NPN output sensor The NPN sensor output, also known as OC gate output, is based on the principle of open collector output of a transistor. The principle of NPN type OC gate output is whether the output of the NPN transistor and GND are short-circuited. When the control is active, the transistor is turned on, the output and the GND ...

The displacement sensor has no sliding contacts, is not affected by non-metallic elements such as dust during operation, has low power consumption, and has a long service life, so it can be used in various bad conditions. Displacement sensors are mainly used to intelligently control the analog quantity of automation equipment production lines. The displacement sensor selects laser three...

1. The output working voltage of the proximity switch is selected, usually DC type DC24V or AC AC250V optional; 2. Proximity switch output mode selection, usually NPN-normally open, NPN-normally closed, PNP-normally open, PNP-normally closed, 2-wire normally open, 2-wire normally closed, DC 3-wire, DC 4-wire ...

Torque sensor is a sensor widely used in the mechanical category, which can measure the torque of rotating objects, and torque sensors have a wide range of application scenarios, and several typical application scenarios will be introduced below. First of all, the short-term sensor is widely used in the automotive industry to measure the engine and transmission.

The prevailing understanding of sensors is to transmit sensory information to the machine, the same type of sensor, transmit different sensory information, we also know that the senses are the organs that sense external things to stimulate the machine, such as our eyes, stomping and nose for the machine, the sensor can realize all the sensory information, so many axes ...

Encoders can be classified as follows. 1. Classification according to the engraving method of the code disc (1) Incremental type: that is, every time the viewpoint of the unit is rotated, a pulse signal is announced (there is also a sine and cosine signal, and then it is ...

The barrier and barrier are composed of four parts: the input signal processing unit, the barrier unit, the output signal processing unit, and the power supply. Depending on the direction of the signal, a substantial safety plan is added to the input or output unit, which then forms a barrier and a barrier. Traditional barrier and safety ...

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 ...

In the process of application, the sensor will inevitably be affected by the environment, temperature, dust and other factors, so that the equipment is aging or wearing, and if these problems are not dealt with in time, it will bury potential troubles for the future use of the equipment, resulting in large and small problems, and ...

An encoder is a device that converts angular or linear displacement into an electrical signal. The former becomes the yardstick, and the latter is called the yardstick. According to the readout method, the encoder can be divided into two types: touch type and non-touch type. The touch type selects the brush output, and a brush touches the conductive area or the insulating area to represent the shape of the code.

(1) Electronic ruler When the electronic ruler is used to a certain moment, in the face of aging problems, we should pay attention to the fact that if the seal is now aged, and there are many impurities, water mixtures and oil, then it will affect the touch resistance of the brush, resulting in the continuous beating of the displayed numbers.

Photoelectric switches are what we generally call sensors. The national standard GB7665-87 defines the definition of the sensor: a device or device that can sense the measured part of the rule and convert it into a usable signal according to the certain rules, which is generally composed of a sensitive element and a conversion element. ...

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 talk about how the sensor is selected in the early stage. The use of the sensor in practical operation is relatively common and may be practical ...

There are three goals of precision: precision, correctness, and precision. precision It sheds light on the sloppy nature of the measurement results. That is, for a certain stable goal (to be measured) by the same measurer ...

Resistive strain gauges, elastomers, and detection circuits are the first and foremost parts of the equation. An elastomer is a special shaped structure. It has two functions, firstly, it bears the load of the force on the cell and the external force, to achieve a relatively static equilibrium, and secondly, it ...

1. Select the type of proximity switch according to the detected object. If the detection object is metal, the inductive proximity switch is preferred, and if the detection object is non-metal such as wood, plastic, paper, water, etc., or smaller and finer metals, the capacitive proximity switch should be selected. ...

1. The device mode of inclination sensor is divided into two types: horizontal device and vertical device, but whether it is a horizontal or vertical device, the sensor device surface should be parallel to the face of the measured object when installing, and the influence of dynamic and acceleration should be reduced at the same time. ...

Based on the characteristics of fixed force measurement, the sensor principle structure is selected as a resistance strain force sensor with mature technology and low requirements for the measurement circuit, and the elastomer of one of the key components of the sensor is selected S-beam structure, as shown in Figure 1. When subjected to pressure P, the ...
