Abstract
This paper reports a MENS based viscosity sennsor suitable for in-process measurement in industrial uses. The sensor is based on the vibrating viscometer. However, the vibrating body is unique dual spiral geometry. The viscosity of the liquid is obtained by curve fitting of the frequency response curve of the spirals. In the present study, we propose an improved chip holder having an electromagnet coil to drive a permanent magnet implanted in the vibrating body of the sensor. The frequency response curve obtained in the experiment shows a good agreement with the theoretical curve.
