panel operates on 12v and supplies the necessary power to the encoder and load
pin.
A backup depth system is available to provide another independent depth
measurement. Depth is measured by a frictionless magnetic pickup mounted in
the measuring head. The pickup consists of magnets imbedded in the measure
wheel coupling and two hall affect devices mounted next to the shaft. This
provides a quadarature type measurement. A small display panel is mounted
inside a wireline unit. The panel is designed to be connected to an external AC or
DC supply or operate off internal batteries for up to 15 hours between charges. In
the event of an external power interruption, the unit automatically switches to
battery power. The system is designed to operate without intervention from the
user. When external power fails, the depth display is maintained by the batteries.
A switch on the front of the panel allows different sizes of wire to be measured
accurately without changing the measuring wheels.
The mechanical measurement is made by connecting a “speedometer” cable to
the hub of the measuring wheel. A “Veedor Root” type counter can be used. Step
down adapters are available to convert from a 4:1 to a 1:1 measurement (adapters
on the wheel and in the counter). The mechanical system cannot be adjusted for
different wire sizes so a wheel with a different sized groove must be installed to
make the mechanical measurement correct.
