TWH-20UF Underground Fiber Cable Route Locator
Description
1. Underground Fiber Cable Route Locator can quickly and effectively determine the direction and depth of the underground cable.
1)Direct digital reading shows the depth of the cable: 0-15 meters, 5% accuracy within 3 meters, and 10% accuracy within 8 meters.
2)Automatic probing: Automatically display the true depth of the target pipeline when the locator is placed correctly above the pipeline.
3)Signal recognition: Accurate identification of fiber optical cable and electric cable from three dimensions: signal amplitude, direction, and phase.
4)Current direction indication: An unique technology to display the current direction and phase of the tracking signal effectively improves the accuracy of the searching path.

Technical Parameter Of The Transmitter
This detector is a multi-frequency high-power transmitter with constant power output and automatic matching of external load to ensure that the machine works in the best condition. With the ohmmeter function, it can detect external voltage and test continuous loop resistance which can help determine the nature of the fault.
1) Available frequency option: Output sinusoidal AC signals of 31 frequencies, which are:98Hz、128Hz、256Hz、480Hz、491Hz、512Hz、577Hz、640 Hz、815Hz、982Hz、1.02kHz、1.17KHz、1.45KHz、1.52KHz、4.1KHz、8.01KHz、8KHz、8.44KHz、9.5KHz、9.82 KHz、29.4KHz、33 KHz、38 KHz、65.5 KHz、78.1KHz、80.43 KHz、82KHz、83.1KHz、89KHz、133KHz、200 KHz
2) Fault detection and pipeline identification signal positioning mode, transmission mode, current direction signal SS Low, SS High.
3) Intelligent signal phase recognition function.
4) Ohmmeter function can detect external resistance, and external dangerous voltage prompts.
5) Three kinds of signal transmission: direct connection, coupling, and induction.
6) Automatic load adjustment.
7) Display content: frequency setting, battery status, digital display output current and loop resistance, output mode, external power supply, external voltage warning;
8) Output power can be adjusted by four grades: low, medium, high, and full ;
9) The maximum output current is not less than 1A; the maximum output power is not less than 10W;
10) Large capacity lithium battery power supply enables 8 working hours under full load 

The Parameter of the Receiver
The receiver adopts a 3.5-inch 24-bit color LCD display screen which displays signal strength number, amplitude light strip, compass pointing, left and a right arrow pointing, current direction indication in order to indicate signal strength, optical cable positioning, fault detection, optical cable identification, and depth measurement.
1) Wide peak value, valley value, narrow peak value, wide peak value arrow, peak, and valley value as of 5 displaying modes
2) With broadband receiving technology, it can be customized (within 100Hz-200kHz). Available frequency options are 10 types, which cover 50Hz、60 Hz 、LF 、577Hz、8KHz、33 KHz、82KHz、133KHz, current direction signals SS Low, SS High.
3) Digital direct reading depth range: 0 to 15 meters. Accuracy: ±5% within 3 meters and ±10% within 8 meters.
4) Display content: signal strength, signal amplitude light bar, left and right arrow indication, compass direction indication, current direction indication, current phase display, real-time depth indication, intelligent signal phase recognition, and signal gain.
5) Featuring compass direction guide indication function.
6) Featuring intelligent signal recognition phase function.
7) Optional external letter A-shape bracket for precise positioning of cable faults.
8) External coupling clamp can accurately locate the optical cable.
9) Signal identification: Accurate identification of fiber optical cable and electric cable can be carried out from three dimensions: signal amplitude, signal direction, and signal phase.
10) Current direction indication: An unique technology to display the current direction and phase of the tracking signal effectively improves the accuracy of the search path.
11) Signal strength sound indication with adjustable volume.
12) 3.5 inch 24-bit true color LCD display. The brightness of the backlight is adjustable to suit various environments.
13) Powered by a large-volume lithium battery, which can last for 8 hours to operate.
