1. After the wireless sensor device is installed, it appears to be beating or the number is inaccurate Reason: There is electromagnetic interference on the site, or the signal line and the power line go to the same trunking. Solution: The product function selected by the customer does not meet the on-site working conditions, and it needs to be installed or replaced.

Not all damaged bearings can be corrected, but the cause and extent of the damage to each damaged bearing must be evaluated to prevent or reduce further damage before considering the correction or replacement of a new bearing. There are many reasons for bearing damage, such as improper equipment, dirt invasion, etc.

1. According to the input physical quantity, it can be divided into: displacement sensor, pressure sensor, speed sensor, temperature sensor and gas sensor. ​ 2. According to the operating principle, it can be divided into: resistive, inductive, capacitive and ...

The pressure sensor is an instrument that can accept pressure signals, and it is widely used in railway transportation, intelligent buildings and other occupations. First, prevent solder slag from ...

1. Pay attention to the reasonable distribution of three-phase load In the distribution of three-phase loads, power operators should carefully collect and record the relevant data in the practical operation, so as to be able to guess the status of the electricity load to a certain extent. Secondly, to be able to ...

Problems can arise when pressure sensors are stored or installed when exposed to manufacturing conditions that exceed the limits of the supplier's rules. Here are six factors worth noting: 1. Temperature Excessive temperature is one of the common causes of many problems with pressure sensors, caused by ...

Fiber optic sensors have the advantages of extremely high sensitivity and accuracy, good inherent safety, anti-electromagnetic interference, high dielectric strength, corrosion resistance, integration of sensing and transmission, and compatibility with digital communication systems. High sensitivity ...

Accelerometers are the most important element in engineering vibration measurement. In the test system, the sensor is the first link of data acquisition and profiling, so the selection and correct use of the sensor will directly affect the quality and accuracy of the measured signal. Although people working on engineering vibration know that this ...

1. Spherical cathode structure: In order to fully avoid the tip effect and make the photoelectron emission more stable and uniform, it is necessary to fix the operating area on the cathode, because the ultraviolet tube relies on photoelectron emission and gas multiplication to complete the conversion of the optical signal into an electrical signal and amplify it.

1. How long does it take for the gas sensor to be recalibrated after use: The length of the time distance between the initial calibration and recalibration depends on many factors, generally including the operating temperature, humidity, pressure, what kind of gas the sensor is exposed to, and the length of time it is exposed to the gas. But most of the ...

Photoelectric switch (photoelectric sensor) is the abbreviation of photoelectric proximity switch, which uses the shielding or reflection of the beam by the detected object to connect the circuit by the synchronous loop to detect the presence or absence of the object. When the photoelectric sensor outputs the signal, the signal is occasionally unstable, and many people do not know what to do.

1. Confirmation of the initial void The various types of oscillating sensors should have excellent linearity at a certain void voltage value, so it is necessary to adjust the appropriate initial void when installing the sensor. According to the characteristic curve of the oscillation sensor, the sensor used for oscillation measurement ...

Incremental sensors Only the bearing change information is provided so that the practice bearing is unknown at startup. Each time the index/symbol signal is used to say the zero or zero bit of the device. Detected in the homing procedure. For the commutation of brushless motors, the motors usually have three magnetic Hall sensors, which are ...

The output status of the sensor when the power is turned on or off, whether it is detected or not, is OFF. In particular, when the power supply is turned on, the output condition is OFF for a certain period of time is called the initial reset. But in the following cases, the output will be momentarily ON(OFF) ...

1. The appearance is installed outdoors, and it is recommended to install a sunshade to prolong the service life of the appearance. 2. Wire and cable protection pipes should be sealed to avoid water accumulation. 3. Although the appearance itself is equipped with lightning protection equipment, when the appearance is used in the multi-lightning area, it is advocated to distinguish the inlet and outlet lines on the surface.

1. Transfer heat pipes for heat dissipation. Dynamic torque sensors can be used in the production of viscometers, electric (pneumatic, hydraulic) torque wrenches, it has high precision, fast frequency response, good reliability, long life and other advantages. Installation steps: 1. According to the connection mode of the shaft and the dynamic torsion...

1. When the pressure goes up, the output of the transmitter can't go up. In this case, you should first check whether the pressure connection is leaking or blocked. If you admit that it is not, check the wiring method and check the power supply, if the power supply is normal, then briefly pressurize to see if the output changes, or observe the zero position of the sensor ...

Pick the right adhesive! We need to know the importance of adhesives, many people do not pay attention to the selection of adhesives, the natural frequency of the accelerometer is determined by the degree of coupling of the bond, so it is important to choose the right adhesive. The weight of the accelerometer is also what we have to test.
