Alumina sensor withstands extreme temperatures

Louise Smyth

Morgan Advanced Materials has produced a new type of alumina sensor specially designed for high pressure and high temperature water and sub-metering.

The sensor has been specifically developed to withstand extreme temperatures, making it suited to both heat metering and high temperature fluid metering. Manufactured using Morgan’s specially-formulated proprietary alumina, the sensor solves many of the problems associated with high temperature environments, with a focus on reducing thermal drift and zero flow offset over a large temperature range.

Morgan’s new sensor significantly minimises the flow offset because the material has been manufactured to control the thermal properties of both the internal and external structure. This enables the minimum flow rate range to be kept as small as possible, enhancing the overall accuracy of the reading.

Morgan’s sensor design has been tested up to 100 bar pressure and 150˚C which surpasses the current market requirements for heat metering. This is a direct benefit of using alumina in the sensor design, a material which has minimal expansion properties, and is renowned for its strength and durability.

Due to its thermal stability, the sensor is also excellent for metering of potable water or other fluids. The inert nature of alumina makes a component that is suitable in food and pharmaceutical environments, as well as providing a long operational lifetime.
