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

EnvironmentallySealed/Hardened
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
Time and date Signal strength / current Depth
Mode Fault Detection Battery status
Frequency Bar-graph readout Audio status
Marker type Dynamic Overload Protection / overload
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).
