Latest Patents
Wrest's latest patents include a corrosion monitoring system and a micropower apparatus for low impedance measurements. The corrosion monitoring system is designed to assess the degree of corrosion in metal by comparing a test sample exposed to a corrosive environment with a reference sample in a protected environment. This system utilizes an AC voltage source to generate a square wave signal, which is filtered to produce a sine wave. The innovative design allows for in situ measurements and operates with relatively low current, enabling prolonged operation.
The micropower apparatus for low impedance measurements focuses on milliohm resistance detection. It features a drive circuit that includes a step-up current transformer driven by a square wave oscillator. The monitoring circuit employs low noise pre-amplifiers and full-wave rectifiers to accurately monitor resistance values of test and reference coupons. This technology is crucial for detecting changes in electrical resistance due to corrosion, thereby providing valuable insights into environmental conditions.
