Cathodic Protection Sensor

CATHODIC PROTECTION MONITORING SENSOR

CP-SAT

Cathodic protection is one of the most effective methods for preventing corrosion on a metal surface; it is commonly used for buried and submerged metallic structures, such as ships, offshore floaters, pipelines, and tanks. Cathodic protection is an electrochemical process that ensures that the metal to be protected becomes the cathode of the electrochemical corrosion cell; corrosion occurs in the anode. In this way, it is possible to maintain the integrity of metallic structures in challenging environments.
The CP-SAT sensor is designed to accurately and efficiently monitor cathodic protection voltages and currents. If the threshold values are exceeded, the device sends early warning messages over terrestrial or satellite networks.
CP-SAT is an ultra-low consumption green power device equipped with a photovoltaic panel and supercapacitors with an optional primary battery that guarantees low maintenance costs.
It has 3DC + 1AC analog inputs, galvanically insulated from each other and from the ground, bipolar, and with SW selectable. Firmware and sensor parameters can be programmed remotely with no need for on situ interventions. In additions, an internal storage memory logs the acquired data for later retrieval and in-deep analysis. Its rugged design and construction makes it ideal for installation in harsh environments typically encountered in industrial applications.
