MODEL 5050LL-PTD : Pressure Transducer
The HydroLynx Model 5050LL-PTD Pressure Transducer (PT) combines a submersible probe,
designed specifically for depth and level measurements, with the convenience of an
external signal conditioning circuit mounted in a desiccant box.
The probe's pressure sensing element is isolated from the water by a titanium diaphragm
and the electronics are housed in a titanium body. The PT cable, which is molded
to the body, is a thick wall polyurethane jacketed cable with an integral vent tube
and Kevlar strain relief cord.
The external signal conditioning allows each sensor to have the same calibration
so there is no need to have individual calibration values at the central site computer.
Also, the sensor can be re-calibrated to accommodate the probe's long term drift.
An accurate water level measurement requires a dry ambient air pressure reference
that the desiccant box provides. The PT is supplied with a can of indicating desiccant
that changes from blue to pink when the desiccant bag should be replaced. Both the
can and bag are rechargeable.
