Strain gauges CA 10-20-25 t
Model CA compression sensors are used in heavy duty weighing equipment and measure compression force. The reliable design of such a sensor guarantees its excellent resistance to overloads, including lateral ones.
This model is used mainly in car and platform scales. Due to the features of its design, the strain gauge SA is used even in difficult conditions.
The sensor is covered with anti-corrosion paint, meets the IP68 standard.
