Electrical Resistance Tomography Linear Sensor - ert001

 

SPA ERT sensors comprise of multiple electrodes which must make electrical contact with the fluid within the process volume. The most common geometry is a circular sensor with the electrodes arranged uniformly around the circumference. This approach is suitable for pipeline based sensors for both R&D and industrial applications. Circular sensors can also be fitted to the circumference of process vessels although this tends to be limited to R&D applications. These sensors can be designed to minimise or eliminate any disturbance of the flow through the pipe by making the electrodes non-intrusive. Linear ERT sensors were developed as a more industrial deployable configuration. The electrode array is mounted on a probe which is typically inserted into a process vessel through a nozzle or port.
