PT12-BV Seametrics

Barometric & Vacuum with Modbus & SDI-12 Interface
  • Available as a weatherproof box or 316 stainless steel tube (titanium optional).
  • Provides barometric reference for absolute pressure sensors.
  • Automatically compensates for barometric pressure when attached to a PT12 submersible sensor (SDI-12 only).
  • Measures pressure and temperature.

Description

The PT12-BV barometric pressure sensor comes as a weatherproof box and provides an ideal barometric reference for absolute pressure sensors.

It also offers automatic barometric compensation when used with SDI-12. Simply attach the PT12-BV to a PT12 submersible sensor and receive barometrically compensated pressure readings. No post-processing of data. No vented cable. No desiccant tubes.

Featuring both an SDI12 (v.1.3) interface and a Modbus® RTU interface, the PT12-BV is easy to connect to recorders and existing monitoring networks, making it the preferred choice for many environmental professionals.

Features

Pressure And Level Sensors Type PT12-BV Seametrics
  • Weatherproof box constructed with ABS – IP66/67, fluorocarbon, and Buna N (nitrile rubber).
  • SDI-12 v1.3 interface.
  • Modbus® RTU interface.
  • Barometrically compensate attached absolute sensor for level measurement (SDI-12 only).
  • Operates on low power.

Applications

  • Level measurement: barometrically compensate absolute pressure sensors.
  • Measure vacuum pressure during vapor extraction pilot testing.
  • Supplement aquifer test data in leaky or confined conditions.
  • Accurately measure barometric pressure.

The Seametrics PT12-BV comes as a weatherproof stand-alone box or with an automatic compensation wiring option. The PT12-BV measures pressure, temperature, and supply voltage. The weatherproof box is an ideal barometric reference for absolute pressure sensors. This version features both an SDI-12 interface and a Modbus® RTU interface that makes the product easy to connect to recorders and operates on low power. This makes it a preferred choice for many environmental professionals with existing SDI-12 or Modbus® RTU systems.

With the Compensation Wiring Option , the PT12-BV automatically provides barometric compensation for a single attached absolute PT12 submersible pressure sensor. No post processing of data. No need to use a vented cable or worry about maintaining desiccant tubes. This version features an SDI-12 communication interface, making it ideal for many existing environmental systems.
