Envco – Environmental Equipment

The PT2X-BV is the perfect counterpart to any absolute pressure transducer as it is a Modbus protocol based Barometer that measures local barometric pressure as a reference when a gauged transducer is not practical. Its independent design also makes it ideal for any other applications that requires barometric measurements.
Features

* Measures temperature in addition to barometric and vacuum pressures
* Comes with easy-to-use Aqua4Plus control software
* Aqua4Push Data Upload Utility available for automatic scheduled data collection from multiple sensors with optional FTP upload
* Two versions:
o Weatherproof box
o 316 stainless steel tube (with NPT option available)
* RS485 interface for easy networking with other INW Smart Sensors and with WaveData® Wireless Data Collection Systems

Applications

* Barometrically compensate absolute pressure sensors for level measurement.
* Measure vacuum pressure during vapor extraction pilot testing.
* Supplement aquifer test data in leaky or confined conditions.
