The SS series of subsea pressure and level transmitters, which are suitable for continuous submersion in seawater, use a ceramic pressure sensor, which provides excellent corrosion resistance for harsh seawater applications. They are fitted with a choice of subsea-certified connectors and locking sleeves to suit specific customer requirements.

The housing is available in a choice of seawater-compatible materials, including 316L stainless steel, high grade Duplex stainless steel or Marine bronze. Nominal pressures are from 1bar to 400bar.

All sensors in the series provide dual independent, 2-wire, 4-20mA outputs, with no signal loss over long cable lengths. The sensors are calibrated and supplied with a traceable serial number and calibration certificate. Operating (media) temperatures are from -20°C to +60°C in non-freezing media.

The electronics incorporate a microprocessor-based amplifier, with level measurements made possible by RS485 Modbus RTU serial communication. Impress provides a standard software package, which enables the user to re-range, calibrate and adjust some parameters of the device. There is also a facility to data log via the software, which is useful for checking installation and behaviours of the application.
