Product Description
The S12C has a high corrosion resistant ceramic diaphragm and a Stainless Steel 316L or Marine Bronze housing can be chosen to suit the application requirements.
Measure water depth in the ranges starting from 0-10 metres up to 0-100 metres, including absolute non-vented ranges from 1.5 bar up to 10 bar absolute.
In addition to freshwater applications where a stainless steel housing is adequate for most applications, the S12C can be supplied with a Marine Bronze housing for offshore use where NACE certified materials are required or with a marine bronze housing for general use in seawater.
The digital interface of the S12C submersible pressure and temperature probe uses the SDI-12 software communications protocol which was created to provide a common standard for communicating between field located environment monitoring instrumentation and related sensors. The SDI12 interface is low powered and multiple devices can be connected to one cable reducing installation cost.
For water pipe measurements the protective nose cone can be reomoved revealing a 1/4 bsp male thread fitting. The IP68 environmental sealing where the cable exits the sensor is permanently waterproof to the maximum depth rating of the sensor and also provides a convenient flood protection rating if the sensor is used for water pipe monitoring at installations that are below ground and normally dry.
Product Applications
- Water table depth
- Aquifer water depth
- Wellsite water depth

Measuring water depth in feet
Is it possible to take water depth readings in feet?
Engineering units are selectable via SDI-12 interface and ‘feet of water’ can be selected.
Subsea pipeline hydrotesting
We require a temperature and depth sensor with a digital interface for measuring the subsea temperature during hydrotesting of subsea pipelines. The seawater depth is 60 meters and the cable length required is 100 meters long.
The S12C is suitable for use in seawater if you select the Marine Bronze housing material:

- Part No: S12C-G6000-T-C-100-000
- Pressure Range: 60 mWG
- Cable Type: TPE
- Length of Cable (metres): 100
- Housing Material: Marine Bronze (seawater)
- PC logging software and converter: SDI-12 (standard)
Tide gauge & logger for 10m depth range
I want to use this sensor as a tide gauge over a depth range of 10 metres, and I would like a software kit which would allow me to use a PC as a datalogger?
The Marine Bronze version of the S12C is suitable for use with tidal water, and the USB converter & logging software will allow you to log the tide gauge data on a PC.
