SWL Marine Bronze Submersible Level Sensor

Aluminium bronze housing submersible pressure sensor

Click Images to Enlarge

Analogue output sensor for immersing in seawater to determine depth or change in water level by measuring hydrostatic pressure. This sea depth probe has a Marine bronze housing and Ceramic diaphragm for protection from saltwater corrosion. Select fixed ranges from 10 metres (33 feet) up to 100 metres (328 feet) depth in a number of analogue output configurations including low voltage strain gauge, amplified voltage and current loop output. Also suitable for use in brackish and inland tidal water or any other application where there is the risk of corrosion form a saline liquid.

Product Description

The SWL is specially designed for protection against corrosion in salt water. The body of this submersible seawater level sensor is made from Aluminium Bronze which is a copper alloy with a 10% Aluminium composition and a smaller percentage of Manganese, Nickel and Iron.  Aluminium Bronze is a proven long lasting material used extensively by the marine industry to manufacture components which will be permanently immersed in seawater.

For added protection on permanent installations a TPE coated cable can be specified for the electrical connecion which is highly resistant to damage from long term exposure to seawater.

The SWL IP68 saltwater depth sensor has many different types of analogue output signal to match any application including a 4-20mA current loop signal for installations on ships or offshore platforms, or a mV/V strain gauge output for low battery consumption on isolated environmental monitoring instrumentation at sea or around coastal waters.
