摘要:
The displacement of the first component (2) is measured by means of a spring (3) and a force measurement device (10, 4) in the form of a stationary conductor (10) in the form of a wire. This is accurate, not susceptible to wear, resistant to vibration, shocks or corrosion and economical to use in almost all media, without any special sealing measures, as well as in any pressure range. The invention can be applied to devices used to obtain oil and gas, actuators, blow-out preventers and valves.
