National Contract for Submersible Pressure Sensors

This contract is for the supply of submersible pressure sensors to be used in water level measurement applications associated with surface water, groundwater and tidal water monitoring. There is no maintenance required. The sensors are required to provide standard industry signal outputs such as 2-wire 4-20mA transmitters, and/or digital signal interfacing such as SDI-12, RS232/RS485 using Modbus protocol. The outline performance specificatasks for sensors that can achieve a combined accuracy of better than +/- 0.3...
