LECTURA DE PROFUNDIDAD DIGITAL PARA LOCALIZAR RECORRIDOS DE LÍNEAS UTILITARIAS SUBTERRANEAS
Los nuevos detectores de metales TW-7700 convierten el rastreo de cañerías
y recorridos de líneas utilitarias
subterráneas en un procedimiento sencillo y simple. Solo tienen una perilla para encender y controlar el volumen.
Eso es todo; no tiene controles adicionales y solo un botón que presionar para lograr la lectura digital de profundidad,
en centímetros o pulgadas.El entrenamiento técnico del operador también se reduce a un mínimo con este rastreador
electrónicamente sofisticado. A medida que el operador camina sobre la línea moviendo el receptor de izquierda a
derecha, puede ver en la pantalla una señal de fuerza en forma de porcentaje digital y en forma de gráfica en barras.
Adicionalmente, tiene flechas que le indican derecha o izquierda
y le avisan cuando está sobre el objetivo.
La señal auditiva da un sonido "pulsante" cuando
el operador está a la derecha de la línea y un sonido "continuo"
cuando el operador esta a la izquierda de la línea. Se escuchará un sonido "pico" cuando esta sobre la línea y en la
pantalla se lee "Over Traget" SOBRE LA LÍNEA.
Apretando el botón se puede leer la profundidad de la línea, en centímetros o pulgadas.

TW-7700The state-of- the-art TW-7700 utilizes advanced digital signal processing for precision locating performance yet is extremely easy to use.
The lightweight receiver is simple to use. The display is a large and easy to read LCD that gives the user all the necessary information to
do the job. A digital keypad allows the user to set the volume level, check the battery level, or activate an LCD backlight. Depth measurement
is done at the push of a button.
The transmitter allows the user to locate in either a conductive or inductive mode. A meter and switch make transmitter set up simple and quick.
In the Fisher tradition, the TW-7700 is affordable, tough, and simple to use while providing maximum performance.

The state-of- the-art TW-8800 utilizes advanced digital signal processing for precision locating performance yet is extremely easy to use.
Three active frequencies provided by the transmitter, and two passive modes for tracing without the transmitter, are provided.
The lightweight multifrequency receiver is simple to use. The display is a
large and easy to read LCD that gives the user all the necessaryinformation to do the job. A digital keypad allows the user to select the desired operating mode, set the volume level, check the battery level,
or activate an LCD backlight.
