Flow sensors are precision instruments used to measure the flow rate of fluids (liquids or gases) by converting fluid flow parameters into measurable electrical signals for flow monitoring. Modern flow sensors integrate multidisciplinary technologies such as fluid mechanics, electronics, and materials science to meet various measurement needs, from laboratory micro-flows to industrial large flows. 1. … Read more
1. Force Sensors Force sensors can be classified into one-dimensional, three-dimensional, and six-dimensional types. Six-dimensional force sensors are suitable for high-precision applications such as robotics. A torque sensor, as the name suggests, is a sensor that perceives and measures force. Force sensors can be categorized into three types based on measurement dimensions: one-dimensional force sensors, … Read more
Ceramic sensors have very strict requirements for dimensional accuracy, which is mainly reflected in two aspects. On one hand, the dimensional accuracy of the sensor directly affects its fit during the assembly process and its reliability during use. If there are significant deviations in the sensor’s dimensions, it may lead to difficulties during assembly or … Read more
