We have configured High Water Detectors to address long- standing designs that employ 8 wire and four wire DC circuits, and one of our own design that uses a two-wire AC/DC circuit similar to a Slide Fence circuit. Basic Detector is a four loop electrode. Three major advantages accrue to the S&C, two-wire design: considerably less cable used, low current use enabling solar panel charging of operating battery and significantly improved shunting sensitivity. In the two-wire design, a 215B-2 AC Source Unit generates a 180Hz signal that feeds a 215A-10 Power Unit, which amplifies the signal level and matches the impedance of the line or cable for the circuit that is routed to the 205-3 High Water Detector, or through a series of 205-1 Detectors to the terminating 205-3 Detector. All components requiring power operate on 12DC. Maximum circuit length with a 500 Ohm line relay is equivalent to the resistance of 47 miles of copper-clad line wire (out and back). Recommended circuit includes push-button reset to prevent electrolysis and wave action causing a cycling of the high water detection. Detectors come with two half-clamps that permit mounting of the Detector to a flat surface. Order back halves of the clamps for mounting to pipes or poles. Contact us for a detailed application guide for High Water Detectors.
