Load Cell / SM35-AK-2 Load Cell
Product Categories Load Cells
SM35-AK-2 wired load sensor is designed for well power diagram test of oil pumping unit. It is a load sensor with high anti-interference performance. The product adopts standard MV signal output and fully sealed design, and can work in harsh environments such as high temperature, high cold, high humidity, and high radiation. It is currently widely used in the oil pump power diagram measurement system. The high reliability design adapted to the industrial environment, as well as the characteristics of high precision, simple installation, convenient maintenance, environmental protection and durability have won the recognition of users. It has been promoted and applied not only in major domestic oil fields such as Shengli, Daqing, North China, Changqing, Xinjiang, and Qinghai, but also in some overseas oil companies.
