PT-14
CABLE AND PIPE LOCATOR
In conjunction with low frequency generators (such as LFG-50, LFG-200 or LFG-2500) in tracing and fault location sets, the locator PT-14 is used as a receiver of electromagnetic signals when searching the route and determining the burial depth of underground utilities, pinpointing insulation faults in power cables, and identifying a correct cable from a bunch with an inductive method.
The PT-14 locator may also used autonomously (in passive mode) for locating energised communication lines using induced signals of various frequencies.
STAND-ALONE OPERATION IN PASSIVE MODE
PT-14 can operate in a passive mode without a generator, detecting signals of the industrial mains frequency at 50 Hz, as well as frequencies of the cathodic protection systems, telephone signals, etc.
BRIGHT COLOUR DISPLAY
Colour instrument display indicates rout and burial depth of the utility line under test, strength and direction of the current in it, and other useful operating parameters.
CABLE ROUTE DIRECTION
PT-14 allows to monitor the position of the utility under test relative to the locator as well as indicate the direction of the current flow.
GPS & BLUETOOTH
Optional GPS module records geographical coordinates of the traced objects, which may subsequently be exported via «Bluetooth» to a PC for mapping.
LIGHT WEIGHT AND DURABILITY
PT-14 weighs only 1.7 kg including a built-in rechargabe battery. Small weight and durability make this cable and pipe locator optimal for field operation.
