(11) 4-20mAC output two wire connection& 2. Product features: 1. Sensitivity: The sensitivity factor of diffusion silicon resistance is 50-80 times higher than that of metal strain gauges, and its full range signal output is around 80-120mv. Good adaptability to interface circuits, due to its input excitation voltage, large output signal, and no mechanical component losses, resulting in extremely high resolution& nbsp;2、 The sensing, conversion, and detection of the diffusion silicon pressure sensor are integrated, without mechanical components connecting the conversion process, so the repeatability and hysteresis error are very small. Due to the good rigidity of silicon materials, the linearity of shape sensors is also very good. Therefore, the overall attitude is very positive. 3. Reliability; The elastic deformation of the diffused silicon film is in the order of microstrain, the large displacement of the film is in the order of micrometers, and there is no mechanical wear, fatigue, or aging. Long average * time, stable performance, reliability, shock resistance, and lightning protection design; Laser resistance temperature compensation, with adjustable zero and range on site; Wide range of corrosion resistance, suitable for various media; Overload and strong capability, stable performance. 4. The frequency response is generally within 50KC due to the inherent frequency of the membrane silicon material. The manufacturing process adopts integrated technology, and the area of the membrane can be very small. Coupled with a rigid structure pre installation design, the frequency response of the sensor is very fast, and the bandwidth can reach zero frequency to 100 kHz& nbsp;5、 Good temperature performance; With the advancement of integrated process technology, the four resistance characteristics of diffused silicon films have been further improved. The original manual compensation has been replaced by laser resistance adjustment and computer automatic adjustment technology. The zero position and sensitivity temperature coefficient of sensors have reached the order of 10-5/℃, and the working temperature has also been significantly increased& nbsp;6、 Good resistance to electrical breakdown; Due to the use of materials and assembly processes, the diffused silicon sensor can not only operate normally at 130 ℃, but also withstand the impact of 1500V/AC voltage in strong magnetic field and voltage breakdown tests, with a three-level anti induced lightning design& nbsp;7、 Good corrosion resistance; Due to the excellent chemical corrosion resistance of diffused silicon materials, even if the pressure surface of the sensor is not isolated, it can adapt to various media in ordinary use. Silicon materials have good compatibility with silicone oil, making it easier to achieve structural processes when using anti-corrosion materials for isolation. In addition, its voltage, current, and power consumption make it suitable for many products of the same type and function, with a good performance ratio. The product core adopts 316L stainless steel isolation membrane, and the product shell is made of 304 stainless steel. (For more occasions, such as long-term seawater matching usage environment, it is recommended to choose 316, 316L, or 317L stainless steel materials for better use. Unless otherwise specified, 304 material is default at the factory); 3. The product component liquid level transmitter (soft wire input type) is composed of a shell, amplifier, wiring terminals, protective caps, hollow wires, etc. According to user needs, a pointer meter and LCD meter head can be selected for display. 4. Product installation precautions& nbsp;                      (1) Choose a place that is easy to operate and maintain for installation; (2) Should be installed as far away from vibration sources as possible; (3) Try to stay away from heat sources as much as possible; (4) When installing the input type liquid level transmitter, the metal should sink into the bottom of the container; (5) Some parts (measuring parts) should avoid contact with sediment or mud at the bottom of the object being measured, or be equipped with anti blocking support frames. (6) The wire is a specially made waterproof wire, and wear, puncture, and scratch of the wire should be avoided during installation and use. If the above problems exist on site, protective measures should be taken for the wire. If such problems occur and cause malfunctions, the cost of repairing the wires will be charged If you encounter any problems during installation and use, please contact our company. In case of any abnormalities in the product, please do not open it for repair without authorization. fiveProduct installation diagram: Shandong Zhuoxin adopts innovative technology and superior materials, with a technical team and strict quality control process flow, ensuring stability.
