Engineered Vibration Sensor Test Methods – Blessing

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.

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...

Photoelectric sensors are generally composed of three parts: transmitter, receiver and detection circuit, and its operating principle is to first convert the measured change into the change of the optical signal, and then convert the change of the optical signal into the change of the electrical signal (this part is called the "photoelectric effect"). According to the detection method, it is not ...

Sensors and transmitters are thermal surface concepts. A sensor is a general term for a device or equipment that can be measured by rules and converted into a usable output signal according to a certain rule, which is generally composed of an active element and a conversion element. When the output of the sensor is a regular canonical signal, then ...

1. Classification according to the engraving method of the code disc (1) Incremental type: that is, a pulse signal is announced every time the viewpoint of the unit is turned (there is also a sine and cosine signal, Then it is subdivided and choppered out of a higher frequency pulse), which is generally output for phase A, phase B, phase Z, phase A, ...

The Finder and the Finder are in use in the automotive industry for the first time, and a variety of ways to use them are proposed: RFID is commonly used in the automotive industry for tracking and traceability. There is a growing demand for customized treatment solutions.

1. Slotted photoelectric sensor A light transmitter and a receiver are mounted face to face on either side of a slot is a fork photoelectric. The luminaire announces infrared or visible light, and the light receiver receives the light unobstructed. But when the object to be detected passes through the trough, the light is blocked ...

An accelerometer is an electronic device that measures the force of acceleration and converts it into a signal. It is possible to calculate the skew angle of the device relative to the horizontal plane, and analyze the equipment movement method through the analysis of dynamic acceleration. The requirements for sensitivity are very high, in fact, no matter what type ...

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

1) The operating voltage of the safety equipment connected to the safety barrier shall not exceed the maximum acceptable voltage of the safety barrier. Otherwise, it should be isolated from the system by using techniques such as optical resistance insulation, or using barrier safety barriers; ...

The ultrasonic switch can be parameterized via two buttons on the side of the sensor. The width of the ultrasonic sound cone also allows the sensor to be mounted as required. The user can set the switch point according to his needs, and the switch point can be adjusted within 5 minutes after powering on. In more than 5 minutes, if ...

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 ...

There are two main types of encoders, incremental encoders and affirmative encoders. The incremental encoder reads the change in the viewpoint displacement, while the affirmative encoder reads the positive viewpoint of the encoding axis. They are done using three common skills, i.e., optical, mechanical, or magnetic. ...

Torsion bar torque transducer is mainly composed of torsion bar tension spring, rotation-displacement converter, and potentiometer. The main function of the torsion bar tension spring is to detect the torque of the driver acting on the steering wheel and convert it into the corresponding corner value. The angle-displacement converter is a pair of spiral mechanisms that stretch the torsion bar.

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, ...

The use of vision sensors in practical operation is relatively common, and may be useful for the needs of various situations in different industries and fields. No matter how good the instrument is, there is a quality of the instrument itself, and in order to reduce the deviation in the measurement process, the user needs to choose a good quality ...

The servo press drives the fine ball shaft through the synchronous belt to complete the accurate orientation control of the pressure spindle, and the high-sensitivity pressure sensor equipment is at the front end of the pressure spindle, which can detect the load of the pressure spindle in real time. Real-time collection of orientation and load data to complete the fine ...

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 rotary encoder is an opto-mechatronic speed-displacement sensor. When the encoder shaft rotates and the grating disc rotates, the light cut out of the slit of the grating disc is received by the receiving element and an initial signal is generated. Germany is a well-known brand. The signal is reacted to by a follow-up circuit ...

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. ...
