EM Locating Basic Concept

EM Locating• Digital EM Transmitter and Receiver

• Wide Range of Active Frequencies (163Hz-428KHz)

• Passive Frequencies (Power and Radio)

• Wide Range of Transmitter Power Output Voltages (30V-90V)• Higher output Voltages overcomes Impedance

• Transmitter Output Wattage Range from 1W (low power) to 10W (highest)

• Connection Options• Direct Coupling• Close Induction• Induction

Tuned Resonant RF Antenna A Complete Solution of

Form Factors and Depth Ranges

• Precision accuracy• Tolerant to congestion • Outlasts life of the facility• RFID identifies facility

attributes• Ease of use, simple• Cost effective

How it Works

Leading Applications

RDIF and EMS

GPS in the Utility Industry

High Accuracy GPS• Integrated external high

accuracy GPS receivers with tablet computers• Sub-foot quality data in real time • No need for post processing or a base

station• Field data directly inserted into the

GIS (with controls)• Integrated receivers, so far . . .

• Navcom• Geneq• Trimble

Intelligent Utility Software• GIS-based software that

operates on smart phones and tablet computers• Creates GIS features in the

field• Update GIS feature attributes

in the field• Attach inspection records to

GIS features• Barcode readers for asset

management

• Real-time data transfer from field to office

• Cloud computing options

Damage Prevention Enhances Public Safety

• RFID devices installed with utility infrastructure for locating directional drill shots, sewer laterals, tees, dead ends, directional changes, and at regular intervals open trench installations

Integration Overview• Detection of all commonly-used RF utility markers

• 9 frequencies - near surface, marker balls, mid and long range

• Rapid marker response for quick searching

• Precise marker depth• Automatic marker depth

• Scan for RF markers, EM or both simultaneously

• GPS and data logging (Manual of 1 sec auto) • Bluetooth • USB

• Easy interface to mapping databases

Data Collection• Measures and stores key usage parameters every second – e.g.

• Over 1 year capacity (2 GB)• Tamper-proof memory / software

• Data supports:• Usage analysis / work validation• Map creation / update • Training records / need identification

CD / FF state Accessory in use GPS data

Data Exporting• Survey measurement data that has GPS data

incorporated can be uploaded from locator and exported directly into Google Earth etc – uses Keyhole Mark-up Language (KML).
