The non-CANbus cameras have a fixed sonde frequency, either 512Hz or
33kHz, which cannot be changed. The Camera body has a collar that indicates
which frequency you are using (see Figure 18). A yellow collar indicates a
33kHz sonde while a white collar indicates either a 512Hz sonde or a no-sonde
camera.

Maxprobe 44mm Camera
The Maxprobe 44mm Camera is a sealed, self-levelling camera with integrated LED
illumination and may include a magnetic sonde emitting an oscillating magnetic field with a
frequency choice of 512Hz (Model No. 1015-1001-0) or 33kHz (Model No. 1015-1002-0).
The lite version of this camera (Model No. 1015-1005-0) has no sonde fitted. The camera is
designed to enter pipelines for the express purpose of undertaking a visual survey.
Figure 19: Maxprobe 44mm Camera
The camera is designed to navigate pipeline from 50mm diameter up to 300mm diameter
and, for the models fitted with a sonde, be traceable up to a depth of 4 meters in optimal
conditions. The spring to the reverse of the main body houses a flexible braid and is
designed in a way to allow the camera to easily traverse 90° bends in 100mm pipework.
The camera is sealed against water ingress and can be submerged to a depth of 5 meters.
