Abstract
The design is described of a string-type gage without cooling for pressure measurements in liquid alkali metals at temperatures within the 20−500^°C range. The basic components of this gage are a single-electrode electrostatic string-type transducer, a set of bellows, a lever mechanism, and a heated housing. Within the measurement range of 0-6·10⁵ N/m² the relative error of experimental gage specimens did not exceed 1
