Abstract :
Beta gauges are now being used very successfully in many industries and are noteworthy for their long term stability; however, they do not have a very fast response time. Dielectric gauges, on the other hand, have a very fast response time, but inherently for many applications do not possess an adequate long term stability. Therefore, by combining the two gauges in a single installation, an equipment is obtained which has long term stability and high speed response.
