摘要：

This investigation was performed on a vessel heat-engineering bench. The working medium was water under pressure up to it 20.5 MPa and temperature from 20 (cold) to 350A degrees C (hot). The controllers were a beta-emission sensor of level and a Sapfir-22DD differential manometer as the standard. The objective was to determine the characteristics of a beta-emission sensor under the conditions of the working medium. Analysis of the experimental data showed that the indications of the beta-emission sensor and differential manometer were identical and linear as a function of the level of both the cold and hot water. The characteristics of the beta-emission sensor are: minimal response time and measurement error, very small dimensions, serviceability at pressures to 20.5 MPa and temperature to 350A degrees C, at least 10 years life, and energy independence of the primary converter.
