THE EVOLUTION OF THE PORTABLE GPS SYNCHRONIZED CURRENT INTERRUPTER

Introducing the CorTalk PI-1

Based on the award-winning concept that originated with Taku Engineering, MOBILTEX has enhanced the field-proven design of the CorTalk PI-1 Pocket Interrupter to deliver an even more robust, reliable and innovative solution for field Cathodic Protection interruption.

GPS-synchronized CP interrupters have historically been large, bulky devices with heavy external batteries that often required daily charging. Mobilizing to the field with enough interrupters for even small jobs with several galvanic CP systems could require hundreds of pounds of equipment. Often locations are extremely remote and may require plane or helicopter access, which combined with the required timing and equipment creates an expensive, logistical nightmare.

The MOBILTEX Pocket Interrupter One (PI-1) is a handheld, light weight two-channel GPS time synchronized cathodic protection (CP) current interrupter that makes these challenges a thing of the past. Capable of interrupting two CP current sources of up to 1 Amp and 20 Volts each, the PI-1 interruption channels provide standard On/Off cycles from 1-30 seconds and it includes a programmable external relay control. Plus there’s no computer or smart device required to setup so it’s simple to change interruption cycles on the fly.

The PI-1’s rugged, portable design makes it simple to transport enough interrupters for a large job in a single pack. The 15-day battery life allows multi-day jobs to be completed on a single charge and a half-hour charge will supply almost a full day of run time. And with a small solar panel (25 mA @ 6-20 Volts) the runtime is unlimited. Let the PI-1 evolution begin.
