3M Dynatel 2250M Cable Pipe Locator w/ Transmitter 2250

3M Dynatel 2250M Cable Pipe Locator

Innovative technology for locating underground utilities without any doubt
3M™ Dynatel™ Cable/Pipe Locator 2250M and Cable/Pipe and Marker Locator 2250M-iD incorporate advanced electronics to quickly and efficiently trace the path of underground cables and pipes (with metallic tracer wire).

They provide accurate cable/pipe, or Sonde depth measurements, giving a digital readout in inches, feet and inches, or centimeters (user-selectable). Lightweight, compact and well-balanced, these cable and pipe locators allow you to accurately and easily:

• Locate cable and pipe path
• Measure cable/pipe, or Sonde depth with the push of a button
• Display relative signal current in the cable or pipe
• Identify cable using toning
• Tone shorts and grounds in aerial cable
• Identify cable pairs through wet sections
• Locate energized power and CATV cable

Advanced features detect more information about underground utilities
A feature exclusive to the 3M™ Dynatel™ Cable/Pipe and Marker Locator 2250M-iD is the ability to write, read and lock programmed information into the 3M™ Electronic Marker System iD Ball Markers 1400 Series.

Information such as a pre-programmed unique identification number, facility data, owner information, application type, placement date and other details from up to 100 markers can all be stored with date/time stamp, and GPS coordinates*, and transmitted back to your PC through a standard RS232 serial port for enhanced resource management.

Designed to be more accurate, faster and more integrated, the new locators can perform these additional functions:

• Pinpoint the location and estimate the depth of all existing models of properly installed underground passive EMS markers
• Conduct direct depth reading of RFiD markers
• Locate two different marker frequencies simultaneously
• Trace a cable or pipe path while simultaneously finding buried markers along the way

EXCLUSIVE GPS system adds accuracy with ease
The 2250M/2250M-iD locators are now compatible with select GPS/GIS field mapping instruments for real-time mapping of marker placement. The customized Dynatel interface remotely commands the GPS/GIS device allowing even a generalist field technician to perform real-time mapping. Exporting information directly into leading CAD and GIS systems creates an automated paperless system for records updating.

Several unique modes of operation for accurate locates in every situation
For cable or pipe locating, 2250M/2250M-iD locators have a highly accurate multi-antenna design for various user-selected locating modes—Directional Peak, Multi-Directional Null, plus an ultra-sensitive Special Peak mode for extreme depths.

A unique “expander” function makes peaks and nulls more pronounced. Directional Peak mode combines the response from four peak antennas to indicate direction to the cable/pipe while a bar graph and numeric display indicate the sharp and accurate dual-peak response.

Semi-automatic gain set with manual override provides maximum flexibility and control. Multi-directional null mode shows null signal response with automatic gain and shows cable/pipe location and direction on a unique compass-like graphic display.

A simple, easy-to-use system
The 3M™ Dynatel™ Cable/Pipe Locators 2250M/2250M-iD require very little operator training. An RS232 communications port allows interface to an external computer for uploading/downloading of data, unit configuration and remote software upgrades. Estimated operating time is more than 30 hours on eight AA alkaline batteries.

The system consists of two basic components:

• Transmitter with built-in ohmmeter, which also measures the presence of foreign voltage and tests the continuity of the circuit.
• Rugged, one-piece hand-held receiver with large high-resolution LCD display. Bar graph signal strength and direction indicates received signal and proximity to the cable. M-iD versions locate and read/write to all EMS-RFiD markers.

The 2250M/2250M-iD locators use four active trace frequencies (individually or simultaneously) to compensate for varying field conditions. The receiver incorporates passive power, CATV, and auxiliary frequencies that do not require the use of the transmitter. The receiver also offers four user-definable auxiliary frequencies.

With the easy-to-use configuration tool, users can enable or disable any of 22 frequencies. Both the receiver and the transmitter feature a self-test routine that is executed each time the unit is turned on.
