Abstract

The calculation of the pressure generated by a controlled clearance piston gauge depends upon the jacket pressure corresponding to zero clearance between the piston and cylinder, Pz;. The dependence of Pz; on the viscosity of the pressure transmitting fluid, the temperature, and the rate of piston rotation has been measured.

The value of Pz; is nearly independent of viscosity below 60 cp. Above 60 cp, Pz; depends strongly upon viscosity. Variations of Pz; with femperature and rate of rotation are more severe at figher viscosities.

These results are a clear indication that for the most accurate pressure measurements, a controlled-clearance piston gauge must be characterized using the same operational and environmental conditions with the same fluid as in normal operation.
