Some Econo Light Duty system
features include:
1. The Color and Black and White CCD Video 100% solid state cameras are
small diameter, light weight and highly reliable. They have excellent light sensitivity and low
power consumption.
2. Every
PVC camera housing is pressure
tested beyond its rated depth before it is shipped. There are stainless steel screws in the housing
and a brass connector for the cable connection.
The camera’s light source, eight white LED’S (Light Emitting Diodes) do
not normally burn out or need to be replaced and they consume very little
power. The camera and housing together
weigh less than 4 ounces.
3. The
Camera manual pan and tilt
attachment allows the operator, at any time, to tilt the camera from looking
straight down through looking sideways to looking 90° above
horizontal (upward) by pulling up on the camera cable. This can be done in 4” or larger boreholes,
but this attachment must be used in conjunction with the owner supplied pipe
string or a camera weight.
4. The
Camera Support is designed to attach
to the centralizer or the pipe string or the support clamp. It consists of a 3/4” female, CPVC Pipe
Adapter and 2 stainless steel straps.
5. The
Support Clamp has a 3/4” male CPVC
Pipe Adapter that allows attachment to the camera support or the centralizer
and an acetal plastic split clamp that attaches to the main cable and 2
stainless steel support straps. This
takes the tension off of the camera connector.
6. The
adjustable camera Centralizer and/or
a pipe string (see above) can be attached to the camera support’s female pipe
adapter. Use the centralizer to keep the
camera in the center of 2” to 14” bores.
The nylon straps are adjusted outward so their setting is somewhat
smaller than the borehole. The straps
are on an outer pipe while the pipe adapters are on the inner pipe. This allows free rotation of the camera without
rotation of the nylon straps. Thus,
material is less likely to be loosened from the borehole walls by the straps
when the pipe string is turned to rotate the camera head. The centralizer should be used with the
support clamp or the owner supplied pipe string.
7. The
one meter two connector cable is used to connect the camera to the main cable
when using the tilt-head attachment.
8. The
cable is a three-conductor polyethylene coated cable with footage marked at
one-foot intervals (optionally marked in meters). The copper clad steel ground and power wires
each have an average tensile strength of about 75 pounds. The cable is used to support the camera
through support clamp. To view the
picture from the camera, the operator uses an owner supplied TV Monitor, TV/
9. The
various components are connected to and interact through the System Power
Supply. There is a power on/off switch
on the power supply box. The system can
be powered from a 115 Volts AC 60 Hz source through use of the AC power adapter
or directly from a 12-14 Volts DC power source.
The other connectors on the box include, microphone in, Audio &
Video out jacks. For details on when and
how to use these connectors, please see the, “Operating the System” section of
this manual.
10. Optional
attachments include: Cable protector, 5”
B/W Monitor, 5.6” LCD Color Monitor, Side-Looking Mirror, Compass, Dual-dive
light, Tripod for Monitor, and 300 Watt 12 Volts DC to 115 Volts AC inverter.
