The force sensor KM40e is a precision force sensor in membrane construction with integrated miniature electronics for the measurement of compressive forces. The force sensor is fastened to a flat surface with four screws M4. There is a spherical cap with a radius of 50 mm provided for the force transmission. The force is applied with a flat plate against the cap. The strength introduction occurs with a flat plate against the cap. The hardness of the spherical cap is HRC 54. A flattening of the spherical cap from a load of about 20kN is therefore possible.
Environmental protection rating is IP 67.
In contrast to the force sensors of series KD, KDs and LC the lateral forces from about 5% of the nominal load can lead to a measurement error greater than 1%. Therefore, the force transmission must be centric.
The sensor with integrated analog amplifier GSV-13i is a compact measuring system.
The electronics amplifies the strain gauge output signal and allows a simple and direct analog measurement in voltage (0... 10V).
Further variants for voltage (0... 5V) or current (4... 20mA) are available on request.
Option HA (High Accuracy)
