The Seametrics PT2X Pressure & Temperature Sensor is an integrated data logger and pressure/temperature sensor and is designed for monitoring groundwater, well, tank, and tidal levels, as well as for pump and slug testing. This sensor networks with all of the Seametrics Smart Sensor family. IThe PT2X is a microprocessor based digital intelligent sensor designed to measure and record pressure, temperature, and time, using low power, battery operated circuitry.

Pressure is measured with an extremely rugged and stable piezo-electric media-isolated pressure element combined with a 16-bit analog-to-digital converter. This provides extremely accurate and stable pressure input into the microprocessor on the circuit board.

This industry standard digital RS485 interface device records up to 520,000 records of pressure/level, temperature, and time data, operates with low power, and features easy-touse software with powerful features. Constructed with 316 stainless steel or titanium, PTFE, and fluoropolymer, this sensor provides high-accuracy readings in rugged and corrosive field conditions. 

Two replaceable 1.5V AA batteries power the PT2X. (Auxiliary power supplies are available for data intensive applications.) The unit is programmed using Seametrics’ easy-to-use Aqua4plus 2.0 control software. Once programmed the unit will measure and collect data on a variety of time intervals. 

The PT2X can be used with the free Aqua4Plus 2.0 software, or use your own Modbus RTU or SDI-12 software or logging equipment to read measurements, thus tying into your existing systems and databases.
