Envco – Environmental Equipment

The PT2X is powered internally with two AA batteries or with an auxiliary power supply for data intensive applications. Envco offers alkaline, rechargeable, and other auxiliary power systems. At the rate of four measurements per hour, the unit will run for a year on its internal AA batteries.

FEATURES
• RS485/RS232 interface
• Small diameter
• Pressure, temperature & time
• 130,000+ records / non-volatile
• 316 stainless steel, Viton and Teflon construction
• MODBUS protocol for RTU & PLC applications
• Easy export to spreadsheets and databases

The PT2X comes with powerful, easy-to-use, Windows based Aqua4Plus software, affording the user extensive control, including real time monitoring, flexible programming, easy field calibration, and a delayed start feature. Aqua4Palm is available for Palm based handhelds, allowing the user to create test sessions, examine data, and monitor real time readings with the convenience and portability of a PDA.

APPLICATIONS
Due to its rugged construction, proven reliability, and datalogging capability, the AquiStar PT2X can be used to replace analog sensors with separate dataloggers. Units can be used to monitor groundwater, well, tank and tidal levels, as well as for pump testing and flow monitoring.

The transmitter's end cone is interchangeable with a 1/4" NPT inlet which allows for increased application use and easy hookup.The modular designed AquiStar PT2X can be factory serviced and repaired saving on future upgrade and repair costs.

PSIA = Absolute pressure is zero referenced against a perfect vacuum, so it is equal to gauge pressure plus atmospheric pressure

PSIG = Gauge pressure is zero referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. Negative signs are usually omitted. A gauged sensor must have a vented cable.
