PT12 Submersible Pressure transducer
For Measuring Pressure/Level & Temperature with Modbus & SDI-12 Interface
The PT12 Pressure/Temperature Sensor has been designed to provide trouble-free submersible operation in liquid environments. This sensor communicates via SDI-12 (v1.3) or Modbus® RTU (RS485)protocol. Pressure/level is measured with an extremely rugged and stable piezo-electric, media isolated pressure element and compensated for temperature using our proprietary calibration methodology. Temperature is measured using an on-board digital chip.
This industry standard SDI-12 device is easy to interface with SDI-12 recorders and can be daisy-chained on one cable up to 200 feet, making it a preferred choice for many environmental professionals with existing SDI-12 systems.

A special version of the PT12 is available, designed to measure barometric pressure in reference to absolute pressure. If you are using an absolute PT12, contact us for details on how our PT12-BV can facilitate obtaining barometrically compensated pressure/level.
The PT12 can be used in a variety of applications including:
Monitoring groundwater, well, tank and tidal levels
Pump testing
Flow monitoring
