Anti - corrosion load cell
Mar 03, 2017

Corrosion resistance of the sensor is mainly used in chemical reagents equipment. In the course of the use of chemical reagents volatile and overflow on the conventional ordinary sensor has a great damage. At this time we need to pay special attention to the sensor. First of all, the selection of the sensor is more stress. The sensor material not only affects the processing difficulty of the sensor, but also directly affects the overall performance of the sensor, so we mainly use two kinds of stainless steel. One is 2Cr13, one is 17-4PH. These two kinds of stainless steel material is the sensor is relatively fine stainless steel material. After the material selection is complete, the sensor sealing performance is required. If the seal is not good, the volatile gas and the overflow of the liquid will cause damage inside the sensor, the degree of damage and the length of time depends on the existence of any chemical reagents in the environment, corrosion fast and slow. The sensor needs to be sealed mainly in two places, the first is the strain area is the second outlet hole. These two places are directly connected to the strain resistor. Strain area We prefer jelly filling and laser welding. The cover plate and the elastic body as a whole welded together. Outlet hole selection of the best waterproof pressure line nut, and fill the gap with a sealant. Should be squeezed by the seal will be completely blocked after the entire outlet hole so that you can achieve the effect of completely sealed. At this time a corrosion-resistant load cell was molded.
