(2) Whether the power fuse of the digital display meter is blown. (3) Whether the power supply voltage meets the requirements. 2. The digital display table does not count (1) Passing ...

1. Application in industrial automatic detection and automatic control system Sensors play an extremely important role in industrial automation production. In the petroleum, chemical, electric power, steel, machinery and other processing industries, sensors are responsible for detecting various information.

1. Detection of temperature The optical fiber temperature sensor uses a polymer temperature-sensitive material that matches the refractive index of the optical fiber to coat the outside of two optical fibers that are fused together, so that the light energy is input from one optical fiber to the reflective surface and output from the other optical fiber.

1. Ordinary metal straight tube package temperature sensor The packaging form of this temperature sensor is mostly used in a simple installation environment, and is divided into high temperature temperature sensor, medium temperature or ordinary temperature sensor and low temperature temperature sensor according to the measured temperature range.

The sensor is a kind of detection device, which can feel the measured information, and can transform the felt information into electrical signals or other required forms of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control. Photoelectric sensors and ...

(1) The Ultimate Problem Solver: Solve the most challenging applications by reducing sensor inventory with reliable, durable sensors (2) Regardless of the reflectivity of the target surface, the solution is difficult distance-based applications, including black foam on black plastic, black rubber in front of metal, multi-packing, etc.

The common faults of Banner displacement sensors are described in seven points, the details are as follows: 　　The linear line works on the same principle as a sliding rheostat and is used as a voltage divider, which represents the actual position of the measured position with a relative output voltage. To this outfit ...

Pressure sensors are mainly used in: booster cylinders, boosters, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air conditioning and refrigeration equipment and other fields. 1. It is applied to hydraulic system The pressure sensor is mainly used to complete the closed-loop control of the force in the hydraulic system. When the control ...

The first point is that photoelectric sensors and fiber optic sensors work differently First of all, from the working principle of the two, first of all, the photoelectric sensor works according to the principle of the photoelectric effect, that is, when the light hits the photoelectric sensor made of semiconductors, it will emit light ...

Analog vs Digital Output: This is the first thing to consider. This depends on the interface between your system and the accelerometer. Generally, the analog output voltage is proportional to the acceleration, for example, 2.5V corresponds to 0g acceleration, and 2.6V corresponds to 0.5g acceleration. ...

1. If the electronic ruler has been used for a long time, and the seal has been aged, and there are many impurities mixed with it, and the water mixture and oil will seriously affect the contact resistance of the brush, which will make the displayed numbers keep jumping. At this time, it can be said that the electronic ...

1. Prevent the debris from being deposited in the catheter and the sensor from coming into contact with corrosive or overheated media. 2. When measuring gas pressure, the pressure intake should be opened at the top of the process pipeline, and the sensor should also be installed in the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process pipeline. ...

Pressure is one of the important parameters in industrial production, and in order to ensure the normal operation of production, it must be monitored and controlled. The following are common terms used when selecting pressure sensors: Standard press The magnitude of the pressure expressed by atmospheric pressure is greater than the atmospheric pressure ...
