We often use a pressure sensor, in the course we must pay attention to the protection of pressure sensors, pressure sensors, pressure sensors because although there are stainless steel protection, but the pressure sensor is still very fragile, especially improper use is likely to cause damage leading to loss of pressure sensors . Of course, is a sensor over-range use, do not apply more than the rated withstand pressure. If resistance to pressure exerted more pressure may cause damage. Followed by the use of the environment, to avoid in the case of flammable and explosive gas environments. There is a power supply voltage and load short-circuit, when used do not exceed the operating voltage range. If the applied voltage above voltage range, it may cause cracking or burned. Avoid short-circuiting the load. Doing so may cause cracking or burned. Another point that is relatively rare mistake wiring polarity power supply to avoid error wiring. Doing so may cause cracking or burned. A pressure sensor and then use the time we must learn how to protect it, otherwise it can easily be damaged resulting in production losses, of course, as long as we operate according to the manufacturer's instructions correctly, to avoid the above-mentioned several problems, pressure sensor can still work long hours a. Some of the pressure sensor can be used to a few years or even ten years. Mainly to learn how to protect it. Wiring sensor has always been one of the procurement process consulting clients have the most problems, digital pressure sensors, many customers do not know how the sensor connection, in fact, a variety of sensors wiring are basically the same, pressure sensors generally have two-wire , three-wire, four-wire, and some have five-wire system. Two-wire pressure sensor is relatively simple, general customers know how wiring, a cable to connect the positive power supply, pressure sensors wholesale, and the other line is the signal line through the instrument is connected to the negative power supply, this is the simplest, pressure sensor , pressure sensor in three-wire system is based on two-wire plus a line, this line is directly connected to the negative power supply, compared with two-wire a little trouble. Four-wire pressure sensor must be two power inputs, the other two are the signal output terminal. Four-wire voltage output instead of mostly 4 ~ 20mA output, 4 ~ 20mA called pressure transmitter, most made of two-wire system. Some of the pressure sensor output signal is not amplified, only a few dozen mV full-scale output, but some pressure sensors inside the amplifier circuit, the full-scale output of 0 ~ 2V. As to how to the display meter, depending on the range of the instrument is how much, if any, and the output signal compatible gear, it can be measured directly, or to add signal conditioning circuitry. Five-wire and four-wire pressure sensor less, five-wire sensor market is relatively small.
