Spotlight: Pipe & Cable Locating Equipment

July 2011, Vol. 66 No. 7
MALA's Easy Locator.

The vLocPro system is a completely new system for pipe and cable location. The system has a classic look with an intuitive user interface designed to minimize training needed when transition from other manufacturers' equipment. Both receiver and transmitter allow use of any frequency between 50Hz and 200 kHz. The usual broadband Passive Power & radio modes are also accompanied by specific narrow band, 50Hz & 60Hz narrow band modes. Both transmitter and receiver operating systems can be upgraded via a standard USB interface - making for the ease of additional software options and enhancements from your PC. 800.638.7682, www.vivax-metrotech.com

The PL-1500 LOW Transmitter has 3.0 watts power output in the Direct Connection Mode, allowing locates for longer distances. Use the Inductive Mode to quickly locate shorter pipes and cables. The PL-1500 Receivers are very light-weight, weighing only 3.5 pounds, with large, easy-to-read LCDs and thumb-controlled switches. The single vertical bar (line) in the receiver displays above is the "Peak Hold" feature. The Peak Hold shows the maximum signal measured in the last 3 seconds. Press the "DEPTH" switch, and the depth is displayed (down to 16 feet deep). The PL-1500 Transmitters show the actual, measured Output Current in the Direct Connection Mode. If the Output Current is low, then increase the Output Power Level or move the Ground Stake. 920.347.1788, www.ssilocators.com

The 980T dual-purpose electronic transmitter can transmit signals to any Ditch Witch pipe and cable locator or fault locator. Equipped with automatic mode-sensing capability, the 980T detects the type of cable that is plugged in and automatically transmits the appropriate signal to the fault or line locator. The 980T also can transmit to a line locator via direct line connection, induction clamp or induced broadcast signals. Simultaneous 8 and 29 kHz transmission to a line locator makes an alternate signal available if one is hard to detect, while higher frequencies locate metallic lines with insulators that weaken or block low frequencies. Fault-locating mode includes a pulse rate of three to four seconds and an LCD display of pulse; fault impedance indicator gives an approximate value to the fault. 800.654.6481, www.ditchwitch.com
