PT2X Pressure Level Sensor


PT2X is ideal for observing flow patterns, testing pumps, and monitoring groundwater, well, tank and tidal levels.

A pressure and temperature sensor with integrated datalogging, this sensor is constructed with 316 stainless steel, fluoropolymer, PTFE—providing highly accurate readings in rugged and corrosive field conditions.


Pressure & Temperature with Datalogging

  • Records pressure and temperature
  • Integrated datalogger collects up to 520,000 records
  • Thermally compensated for volatile conditions
  • Easily connects with other sensors via RS485 network
  • Includes Aqua4Plus and Aqua4Plus Lite control software


  • Measures pressure, temperature, and time
  • Available in absolute, gauge, or sealed gauge
  • Thermally compensated—great where water temperatures vary, such as in streams or industrial tank applications
  • ± 0.05% FSO typical accuracy
  • Low power—2 internal AA batteries
  • External power options (12 VDC) with AA’s acting as backup
  • 316 stainless steel, fluoropolymer, and PTFE construction (titanium optional)
  • Available for both Modbus® and SDI-12 protocols


  • Non-volatile memory—your data will not be lost in the event of a power failure
  • Flexible, multi-phase logging sequences—measure at your specified intervals and save instructions to disk for reuse
  • Pause logging feature—temporarily pause the logging while repositioning or transporting sensor
  • Delayed start feature—state a specific future start time, making it easy to set several sensors to start at the same time

Cabling & Networking

  • Wireless connectivity
  • RS485 network—allows several sensors to be networked together and provides much longer cable leads
  • Field-serviceable connectors—easily remove the connector, route cable through well seals, walls, or conduit, and then replace connector
  • Available cableless or with a variety of cable options, including polyethylene, polyurethane, and FEP


  • Comes with free Aqua4Plus control software to get you up and running immediately
  • View your data in real-time
  • Easy export to spreadsheets and databases
  • Barometric compensation utility for use with absolute sensors
  • Update sensor via firmware while in the field—great for future updates or custom development


  • Wetland monitoring
  • Well, tank, tidal levels
  • River, stream, reservoir gauging
  • Stormwater runoff monitoring
  • Resource administration
  • Pump and slug tests
