Diaphragm Seal Level Transmitter

WE3051LT  Diaphragm Seal Pressure Level Transmitter series is mainly used for measurement in the following occasions: viscous medium at high temperature, easy to crystallize medium, precipitation medium with solid particles or suspended matter, strong corrosive or highly toxic medium can eliminate the leakage of pressure pipe ,the continuous accurate measurement interface and density,occasions that require high hygiene and cleanliness,etc .While in the production of food, beverage and pharmaceutical industries, it is not only required that the parts of medium contacting is hygienic standards, but also it should be easy to wash to prevent cross-contamination of different batches of media. Diaphragm seal pressure level transmitter plays an important roles in those occasions mentioned above , Wepower Electronic has been offering  the high grade china made WE3051LT product since the year 2003.
