Abstract

The solution belongs to power measurement technology and can be used in a weight meter and measuring devices rolling. The solution is to reduce performance, increase sensitivity measurement at the expense of the linearity of the output characteristic and increasing sensor sensitivity. The solution is a magnetically flexible sensor the force of which the nucleus occupies magnetizing winding and perpendicular to it and joined measuring and coiling measuring winding, placed at an angle of 45 ° to the direction of the measured force. The new thing is that magnetizing and measuring The windings are placed on each first element, and on each other element the cores have additional windings, connected in series and in accordance with the measuring windings.

Magnetic spring force sensor

The solution belongs to the force measuring technique and can be used in weighing machines and rolling screen measuring devices. The aim of the solution is to reduce the required power, increase the sensitivity of the measurement at the expense of linearity of the output characteristic and increase the sensitivity of the sensor. The solution is a magnetically resilient force transducer, the core of which is magnetized and perpendicular to it and connected in series and coincidently to a measuring coil, positioned at an angle of 45 ° to the direction of the measured force. What is new is that the magnetizing and measuring windings are located on each first core element, and on each second core element there are additional windings connected in series and in agreement with the measuring windings.
