Pressure sensing device for rheometers |
| abstract |
An improved rheometer plate (6, 7) includes a smooth sensing surface (12) with monolithically integrated miniature pressure sensors which do not interfere with the smooth surface (12). Pressure sensing diaphragms formed by the smooth surface (12) deflect in response to local pressures against the surface to enable the measurement of unperturbed local pressures of materials sheared between plates (16, 17). The pressure sensors are sufficiently small that measured pressures are considered to be significantly local properties compared to the size of the plate. Normal stress differences and viscosity of fluid are measured accordingly. The membrane (10) covers a plurality of wells or recesses (13) with pressure sensors located in the wells (13) to measure the deflection of the membreane (10) over the wells (13). Capacitive or other sensors may be used. The rheometer plate can be used as part of a slit rheometer with a slit of varying dimensions. |
