The new house is in hand, and many friends are planning to decorate it. Careful friends will definitely pay attention to various kinds of decoration information first, and after reading so much, it may be dizzy. Well, Xiaobian now takes everyone to look at the experience of people who have come to the building. note! Look at the experience of others, learn from the past and learn lessons! Now, Xiao Bian takes everyone to see if the owner is full of belly decoration "bitter water"!
Owner Readme:
Due to the lack of adequate preparation before the renovation, the construction has given me a hard time. Fortunately, it has now been completed. Otherwise, this bone will be tortured. After experiencing this decoration war, I can understand the phrase "hate a person? Then let him go and decorate it!" This bitter experience is only really known to myself, but I also summarized some decoration experience in 3 months. Today, I would like to share with everyone. I hope you will learn from me and don't take my old path.
1, the contract on a black and white writing work is the Office of the ceiling, today want a good ceiling project and the master to discuss, the master actually said to add 300 faster money, because the original ceiling is just the restaurant's ceiling, also said that taking into account my psychology Balance is only 300, or he will not do more than 300. Haven't seen it? Whose ceiling is suspended in half, not to mention the ceiling of the hall written on the contract! (My house construction area of ​​105, water pipe manufacturers installed, gas pipe water heater company row, kitchen bathroom ceiling group purchase is also the manufacturers installed, the bay window is also done by the people to install, the overall kitchen manufacturers do, only the storage room cabinet, the door window The woodworking of sets and baseboards received a clearance fee of 9,500. I still said that the ceiling is only the price of the restaurant, and the living room should be increased!) It is recommended that you sign the contract several times to emphasize repeatedly, so as not to refurbish the company. Play word games with you!
2. When I took 10 days of annual leave, the mason couldn't get into the field. When I went to work, I said that the mason came and wanted to post the tiles. I asked for leave and they decided on the position of the brick. I mentioned waterproof, he said. The new house is not necessary. Dive back at night to find out that you should do waterproofing before posting. The next day, let them do the waterproofing on the phone. The master is unwilling to 100. He actually said that if you didn't buy the material, it will affect the construction time of the mason. I started to say I want to do it now. I didn’t buy it. material. Fortunately, there is a network of waterproof mortars in Nianjia.com and the delivery will be the next day. After waterproofing, I have to do a waterproof experiment. He said I heard that the water should be released in the evening and let you come and let it go the next morning. The next day was just Saturday. When we rushed, the water was gone. The ground did not see any traces of waterproofing experiments. What was even more indignant was that the foreman said it. When he ran over to ask the mason master, the mason master said that the wall had been done. The ground had not had time to do it. Who was right?

The vibration sensor(Vibration Transmitter) is one of the key components in the testing technology of Vibration Measurement. Its main function is to receive the mechanical quantity and convert it into a proportional electric quantity. Because it is also an electromechanical conversion device. So we sometimes call it a transducer, a vibration pickup, etc.
Commonly used vibration sensors are as follows:
1. Piezoelectric resonant
The piezoelectric sheet is used to receive the vibration signal, and the resonance frequency of the piezoelectric sheet is relatively high. In order to reduce the resonance frequency, it is realized by increasing the mass of the piezoelectric sheet vibrating body, and using a spring ball instead of an appendage to reduce the two resonance frequencies and enhance the vibration effect. Its advantages are high sensitivity and simple structure. However, the signal needs to be amplified and sent to a TTL circuit or a single-chip microcomputer circuit, but it is enough to use a triode single-stage amplification
2. mechanical vibration
In the traditional vibration detection method, after being vibrated, the spring ball vibrates at a reduced amplitude for a long time, and this vibration is easy to be detected by the detection circuit. The vibration output switch signal is determined by the output impedance and the resistance value of the matching output. According to the input impedance of the detection circuit, it can be made into a high-impedance output mode.
3. Micro Vibration Sensor
The mechanical vibration sensor is miniaturized, the vibration body is carbonized and sealed, and its working performance is more reliable. The output switching signal is directly connected with the TTL circuit and or the input circuit of the single-chip microcomputer, and the circuit structure is simple. The output impedance is high, and the quiescent working current is small.
Advantages of Vibration Sensors
1. Small size and light weight. It can be applied to some vibration test systems that are greatly affected by the additional mass.
2. It has a wider response frequency range of 4Hz-2000Hz than the magnetoelectric speed sensor, and the mechanical moving parts are not easy to damage
