•
Tighten the threads between parts A & B before tightening the gland on
the cable B & D. Use the correct rubber seal (C) to suit the cable
diameter.
•
Tighten the gland gently using a wrench
– finger-tightened glands are not
tight enough.
When making up the connectors, ensure that the connectors bodies are correctly
threaded, and the cable seal is tight. Incorrectly assembled connectors will allow
water in, which can permanently damage the sensor.
Vented cables
Cables from pressure-based water-level sensors are usually ventilated to allow
for barometric pressure correction. A thin vent tube runs the length of the cable
interior.
The Hydro-Logic
®
Flexi Logger 100 sensor connectors are vented to atmosphere
via a Gore protective membrane. The membrane exposes the sensor vent tube to
atmospheric moisture, while blocking liquid water. The sensor connector has
loose terminal pins which allow barometric pressure to pass from the sensor vent
tube, through both mating connectors and out through the Gore membrane.
There is no need to drill the sensor connectors.
When installing, cut off the vent tube and unused conductors and about 10mm
beyond the end of the outer insulation. Do not crush the end of the vent tube.
Approved sensors
Hydro International have a list of approved sensors which can be supplied with
the Hydro-Logic
®
information.
If you have a sensor in one of the above categories which is not on the Hydro
International list, it may still be possible to use it. Please contact
to discuss support for a specific sensor.
