Installation 6-13
Figure 6-15 Hints on cable layout (1 represents the protective cover)
Do not bend the standard signal cable in more than a 3.94-inch
(10-cm) radius. Bending it into a smaller radius could break the
cable and, for certain sensors, produce kinks in the cable and
create obstructions in the air compensation hose (resulting in
erroneous depth measurements).
The cables of high-resistance sensors (special models) are coated with an additional
transparent FEP jacket that protects the cables against organic solvents, acids, and
lye. Do not damage (such as cut, penetrate, or crush) or remove this protective jacket
under any circumstances.
Handle high-resistance sensors equipped with additional protective
jacket (cables with FEP jacket) with care. Do not damage or crush
the protective jacket in any way.
The minimum bending radius of cables with protective FEP jackets
is 5.91 inches (15 cm). Bending the cables in a smaller radius may
damage the protective jacket, resulting in sensor malfunction.
Combi Sensor with Integrated Pressure Measurement Cell
To compensate for atmospheric pressure, sensors with integrated pressure
measurement cells have an air hose located inside the cable. Do not buckle or seal
this air hose or clamp the hose into hermetically sealed connection sockets without air
pressure compensation. The pressure cell will not be able to measure flow depth
accurately under these conditions.
Pipe Insertion Sensor
The pipe insertion sensor would be most suitable in applications such as closed pipes
that remain full. To install the sensor, screw it tightly into the 1½-inch nozzle using a
cutting ring and spigot nut. The cutting ring of the sensor will warp during
installation and, therefore, cannot be used again. Therefore, to obtain new cutting
rings, please contact an ADS representative..
Another installation option would involve using a ball valve to
allow for sensor removal without applying pressure or a
retractable fitting to allow sensor removal and replacement under
operational conditions.
