Your details are sent to our sales team. We will contact you within 24 hours.

Radiodetection Smart Interrupters are Solid State Cathodic Protection Interrupters for pipeline technicians.

Smart Interrupters can be used to modulate the Cathodic Protection (CP) signal to aid identification of stray currents, as well as enabling the location of coating defects along the pipeline.  Radiodetection’s SI 50 and SI 100 feature high current switching capability, with circuit protection and user programmability.

SI 50 and SI 100 Smart Interrupters are a solid state interrupter, designed for use by the trained corrosion technician on cathodic protection systems in outdoor locations. For safe operation of the equipment please ensure you read, understand and follow the instructions in this guide.

The Smart Interrupter provides a means of placing a characteristic signature on pipes by interrupting the flow of cathodic protection (CP) current. The Smart Interrupter is specifically designed for use with the Radiodetection Stray Current Mapper (SCM) and Pipeline Current Mapper (PCM+) but can also be used as a stand-alone interrupter.
