| Inductive Resistance: Inductive
Resistance corrosion monitoring probes have many similarities to ER probes but offer
significantly improved sensitivity. Mass changes in the sensor element are detected by
measuring changes in the inductive resistance of a coil, located inside the element. For a
given sensor element life, these probes will tend to show-up a change in corrosion rate
much sooner than the equivalent ER version.
| Inductive Resistance probes require temperature
compensation, similar to ER probes. Like ER probes, the sensors can be used in a broad
range of environments. They can be considered for low conductivity and nonaqueous
environments, where electrochemical techniques are generally unsuitable. |
Inductive Resistance sensors are generally reported to be at least two orders of magnitude
more sensitive than the corresponding ER type.
