Spx Rd7000+ Precision Cable Locator





SPX RD7000+ Uitility Cable, Pipe & RF Makrker Locator For Preicison Pipe Locating

RD7000+ – delivering fast, accurate, reliable and repeatable locate information for all utilities
Locating specific pipes, cables and markers in large underground networks is becoming increasingly complex. Ground distortion effects, caused by differing soil types and proximity to other conductors, make the operator’s job more difficult and time-consuming. The most important requirements for a locator under these circumstances are ease of use, accuracy and reliability. Radiodetection’s RD7000+ addresses these needs with several groundbreaking features that deliver accurate, reliable and repeatable measurements.

The RD7000+ is a complete range of locators designed to meet specific industry needs. RD7000+ can locate and automatically estimate depth of pipes, cables and most commonly used RF markers, allowing for faster and more accurate surveys, even in areas of high level of electrical interference.

The RD7000+ is ergonomically designed to deliver a superior performing locator that provides the user with a light weight, energy efficient and exceptionally well balanced tool that is comfortable for extended periods of use. Despite its weight and form, the RD7000+ retains the environmental durability associated with an IP54 rating, meaning you can operate it in almost any environment.

The locator and transmitter both feature large, high contrast, backlit LCD screens that provide the user with clear information in any light conditions. The intuitive and responsive user interface has easily identifiable icons that are consistent across the locator and transmitter range, ensuring straightforward operation.

RD7000+ units are Centros enabled. Centros is a measurement engine based on more than 30 years of continuous development, combining new and innovative algorithms with established software on a high-performance processor core. Centros improves location accuracy and repeatability and delivers timely responsiveness in the field.

Allows the operator to quickly and easily follow the target line by visually indicating the relative orientation of the target cable and the locator. By indicating the alignment of the target cable with the locator, Compass helps to improve accuracy when measuring depth.

Dynamic Overload Protection
Extends the RD7000+’s locate capability into areas where other products fail by automatically filtering out large and unwanted signals – aiding accurate location of the target pipe, cable and marker even in electrically noisy conditions, for example near High Voltage overhead cables.

Peak/Null Mode
A tool to identify the effects of field distortion due to ground conditions or nearby utilities. Simultaneous display of Peak bargraph response and proportional Null arrows allow a quick assessment of locate conditions.

Marker Locator
RD7000+ marker locators detect all commonly used RF utilities markers. TruDepth automatic depth estimation, without the need of two-steps measurements, allows for faster and more accurate surveys. Combined mode allows scanning for pipes, cables and markers all at the same time.

Data Logging
On board memory (PLM and TLM models only) allows over a year’s worth of locate history to be stored at one-second intervals. Data can be backed-up to a PC at any time, giving virtually unlimited record keeping for the life of the product. Retrieved data can be analyzed to aid in ensuring compliance and identifying training requirements

Remote Calibration
Using the supporting Windows® compatible software, locators can be checked for correct calibration and operation over the internet, without the need to return the RD7000+ to a service center. Operators can then print, email or save a calibration certificate, or book a service should any issue be detected.

DL/DLM – Water & Pipline Industry
Specifically designed for the water industry, and supported by the wide range of Radiodetection pipe location accessories.

The DL and DLM locators are designed to detect not only active and passive frequencies but also four different sonde signals. This makes the DL range ideal not only for standard pipe, cable and markers (DLM model) location but also for locating deep, underground dirty water pipes and drains where the pipe material does not allow the use of standard locating technology but where sondes can be deployed. The DL and DLM are also capable of locating Cathodic Protection System (CPS) signals applied to pipelines, further extending its versatility.

Four different sonde frequencies allow the DL/DLM to locate pipes made from a wide variety of materials including: cast iron, plastic (PE), clay, fiber, concrete and brick. DLM models allow users to document surveys using SurveyCERT.

The DL range is the ideal partner for the Radiodetection and Pearpoint ranges of inspection equipment. For details of available sondes and accessories see www.radiodetection.com.

Featuring Compass and Dynamic Overload Protection as standard, DL and DLM aid pipe, cable and markers (DLM only) location even in electrically noisy environments.

Radio Detection TX-5 Transmitter
All models feature constant current across their entire bandwidth in either direct connect, clamp or inductive mode. The transmitters are light-weight (2.9kg), well-balanced and IP54 rated to cope with demanding environmental conditions. Each model has a removable accessory tray and a weatherproof battery compartment. A large, high contrast, backlit LCD screen provides the user with clear information.

90V output capability: All transmitters offer both 30V and 90V output options, resulting in higher signal current delivered on high impedance target lines than typical transmitters that only offer a 50V output. Higher signal levels are more locatable, and travel over longer distances.

SideStepauto™: allows the transmitter to calculate the optimum frequency based on ground impedance. The transmitter uses this information to optimize the active frequency. SideStep auto helps to improve locate accuracy and extends battery life.

To support the extended RD8000 iLOC feature set, the Tx-5B and Tx-10B can be ordered with integrated iLOC remote transmitter control.

The transmitter range features Direct Connect and induction frequencies compatible with locators across the RD8000 range, and can be easily customized to match your locator using the ‘model’ feature. The Tx-10B transmitter includes the additional ‘PTL’ model featuring the additional frequencies of the RD8000 PTLM locator.

A multimeter function enables quick measurements of output voltage, line voltage, current, impedance and power.

The transmitters are powered either by 8 standard D-cell batteries (alkaline or rechargeable NiMH) or by the Lithium-Ion rechargeable battery pack (available as an option). Alternatively, the Tx range can be powered from a 12V vehicle source using a Radiodetection approved isolation transformer.

Alkaline battery life can be extended by enabling ECO mode which warns the operator and gradually reduces the power output in low battery conditions (Tx-5 and Tx-10 models only).
