Do you have a sensor which can installed down a tube to measure seawater level in a harbour in order to switch a pump on when the tide comes in? The max depth will be 6 metres and we would require a surface mounted digital display box with 2 relay outputs.
The SWL is resistant to seawater corrosion and can lowered into a tube to measure the hydrostatic pressure of seawater. The SRP-N118 can be mounted to the wall to display the seawater depth and has 2 voltage free contact relays which can be configured to switch on/off at designated depths to control the activation of a pump.
