Experimental determination of cesium saturated vapor pressure in the 483/642 deg K temperature

Journal Article:

Abstract

Test results of saturated cesium vapour pressure in the temperature range of 483.13-642 deg K and pressure range of 15.77-1.389 N/m/sup 2/ by direct static method are presented. The testing system comprises a differential bellows-type pressure sensor, a thermostatic unit and a gas system with V-shaped oil manometer used for argon-assisted sensor calibration. The static sensor characteristic approaches linearity in the pressure range of 10-600 N/m/sup 2/. The greatest non-linearity is observed at low pressures (10-40 N/m/sup 2/) and does not exceed 3-4%. Sensor sensitivity is 0.39 mV/N/m/sup 2/ in this pressure range. The characteristic hysteresis is 0.5% and below. With pressures greater than 600 N/m/sup 2/, the sensor sensitivity gradually decreases by 12% while the characteristic hysteresis increases to 2-3%. A brief description of the experimental procedure is offered. The present results are compared with other authors' data.
