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.
Hydrostatic Level Ranges: 0-10 mH2O (33 ftH2O) up to 0-100 mH2O (328 ftH2O), 0-1.5 bar (15 psi) up to 0-10 bar (150 psi) absolute
Accuracy: 0.25% or 0.1% full scale BSL (11-12 bit resolution)
Output Signal: 4 to 20 mA current loop output and amplified voltage, mV/V uncompensated, 2mV/V ±1% rationalised, 10 mV/V ±1% rationalised and low amplification
Electrical Connection: IP68 sealed with PUR, FEP or TPE coated cable.
Pressure Connection: 1/4 BSP male with protective nose cone
Media Compatibility: Marine bronze CA104 body, Ceramic Alumina Al2O3 diaphragm with NBR, Viton or EPDM O ring seals, PUR, FEP or TPE cable jacket
Diameter: 25 mm (1 inch)
Special Features: salt water compatible marine bronze housing and ceramic diaphragm
Special Options: TPE cable for improved protection from long term exposure to seawater
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.
