RD8100 PDLG Cable and Pipe Locator
The RD8100 cable locator is engineered to deliver high precision for damage prevention when locating buried cables and pipes. This advanced range of underground utility locators offers integrated GPS and usage logging, and is backed with a 3‑year warranty.
- 18 Locate Frequencies - Active frequencies are used in conjunction with a transmitter either in induction, direct connection or signal clamp.
Direct Connection is applying a transmitter signal directly onto the metallic part of a cable or pipe.
Signal Clamping is used to apply a transmitter signal safely to a cable or pipe with disrupting the supply.
The Induction method is used when it is not possible to apply a signal from the transmitter directly on to a cable or pipe.
The choice of signal frequency is an important factor for effective tracing and identification of buried lines. There is no single frequency that covers all conditions.
Low Frequency 512Hz - This low frequency is most useful for line tracing and identification over long distances. It does not couple easily to unwanted lines and it is too low for induction.
Medium Frequency 8kHz - This medium frequency is the most useful general-purpose signal, high enough for induction, with limited coupling to wanted lines. It may not be high enough to impose a strong signal on small diameter line like telecom cables.
Higher Frequency 33kHz - This higher frequency is easily applied by induction to most lines, so it is very useful for initial search. It travels on small diameter lines. However, It couples more easily to unwanted lines, and loses its strength over shorter distances than lower frequencies.
Very High Frequencies 100kHz and Above - This very high frequency range deals with the difficult cases – induction onto small diameter lines in dry sandy soil, and short lengths of cable. It is very easy to apply by induction but it couples very easily to unwanted lines, and does not travel far.
- 4 Sonde Frequencies- Sondes are battery powered signal transmitters for tracing or locating non conductive utilities.
Examples of utilities can be; pipes, ducts, sewers and drains.
- 5 Passive Modes
Peak - For precise locating prior to and during excavation. Displays the strongest response when directly above a cable. Depth and current measurements are also shown.
Peak+- For finding Peak response quickly while checking for the presence of multiple lines or other features which may require extra vigilance. Add Guidance or Null modes to Peak and alternate between them.
Guidance - For checking general direction of utilities as part of a pre-locating sweep. Better for congested areas than Null mode alone. Proportional guidance arrows and differentiated audio tones indicate if utility is to the left or right of the user
Broad Peak - For locating deep lines, or when weak signal levels or interference makes conventional peak locating difficult.
Null - For long distance marking of single utilities in non-congestion areas. Arrows and audio signals indicate where the cable is relative to the operator. A null response is displayed above the cable.
- On-board GPS & Useage Logging- Automatically capture key locate parameters every second, providing a comprehensive picture of individual locates and allowing the user to assess usage patterns over extended periods. The data generated can be used to ensure adherence to best practice, or to identify training needs before poor work habits develop. Usage data can be exported in multiple file formats - for example KML for google maps to confirm where and when work was performed.
- Power Filters - When a signal transmitter can't be connected, tracing individual power lines through dense networks can be a real challenge. Conflicting or powerful signals confuse or combine to create a wash of signal. A single key press uses harmonic properties of power signals to establish if a signal comes from one source, or from multiple cables which you can then trace and mark.
- CALSafe - CALSafe – enabled units can be set to automatically deactivate on expiry of the defined calibration interval, to help ensure compliance with individual company policies. The interval required between services can be customised using the C.A.T Manager software to anything up to one year.
- 4 kHz Frequency - The 4 kHz locate frequency enables lines such as twisted pair telecoms or street lighting to be traced over longer distances. Since such utilities are often found in areas of dense infrastructure, the 4 kHz can be combined with CD to improve trace accuracy.
- Current Direction - Identify your target amongst a number of parallel utilities by applying a specialised CD signal from the Tx-10 transmitter. CD arrows displayed on the locator confirm you are tracing your target.
- Fault Find - Combine the RD8100 cable and pipe locator with an accessory A-frame to identify and pinpoint insulation sheath faults to within 4" (10cm).
- Depth in Power - A depth reading can be taken when directly over a target line when the locator is in passive power mode.
- Passive Avoidance - Allows users to rapidly check an area before excavation using simultaneous detection of the Passive Power and Radio signals carried on underground cables or pipes.
- iLOC - Allows the user to save time on site by controlling the transmitter from distances of up to 1400ft / 450 meters.
- Lithium-Ion Battery - Lithium-Ion rechargeable battery options for both locator and transmitter provide extended runtime with reduced running costs.
